+
+
+
+<p>Some time before the appointment of the Board of Engineers which
+supervised the designing and construction of the New York Tunnel
+Extension of the Pennsylvania Railroad, the late A.&nbsp;J. Cassatt, then
+President of the Company, said to the writer that for many years
+he had been unable to reconcile himself to the idea that a railroad
+system like the Pennsylvania should be prevented from entering the
+most important and populous city in the country by a river less than
+one mile wide. The result of this thought was the tunnel extension
+project now nearly completed; but it is only in recent years that new
+conditions have rendered such a solution of the problem practicable as
+well as desirable.</p>
+
+<p>Previously a tunnel designed for steam railroad traffic, to enter
+New York City near Christopher Street, was partly constructed, but
+the work was abandoned for financial reasons. Then plans for a great
+suspension bridge, to enable all the railroads reaching the west shore
+<span class='pagenum'><a name="Page_2" id="Page_2">[2]</a></span>of the North River to enter the city at the foot of 23d Street, were
+carefully worked out by the North River Bridge Company. The Pennsylvania
+Railroad Company gave this project its support by agreeing
+to pay its <i>pro rata</i> share for the use of the bridge; but the other
+railroads declined to participate, and the execution of this plan was
+not undertaken.</p>
+
+<p>New operating conditions, resulting from the application of electric
+traction to the movement of heavy railroad trains, which had been
+used initially in tunnels by the Baltimore and Ohio Railroad and was
+subsequently studied and adopted by railroads in Europe, made it
+possible to avoid the difficulty of ventilation connected with steam
+traction in tunnels, and permitted the use of grades practically prohibitive
+with the steam locomotive. The practicability of the tunnel
+extension project finally adopted was thus assured.</p>
+
+<p>The acquisition of the control of the Long Island Railroad by the
+Pennsylvania Railroad Company, which occurred in 1900, introduced
+new and important elements into the transportation problem, from a
+freight as well as a passenger standpoint. Previously, the plans considered
+had for their only object the establishment of a convenient
+terminus in New York, to avoid the delays and difficulties involved
+in the necessity of transporting passengers and freight across the
+North River. When the Long Island Railroad became practically a
+part of the Pennsylvania System, it was possible and desirable to extend
+the project so as to provide, not only for a great prospective local traffic
+from all parts of Long Island, but also for through passenger and
+freight traffic to the New England States, and to and from all points
+on the Pennsylvania System, thus avoiding the long ferriage from
+Jersey City around the harbor to the Harlem River.</p>
+
+<p>This paper has for its subject the New York Tunnel Extension
+project, and is intended merely as an introduction to the detailed
+accounts of the construction of the various divisions of the line to
+be given in succeeding papers prepared by the engineers who actively
+carried out the work. The project, however, forms the most important
+part of the comprehensive scheme adopted by the Pennsylvania Railroad
+Company for conducting its traffic into and through New York
+City, and a brief description of this general plan is therefore necessary
+in order that the relations of the tunnel line to the other parts of the
+<span class='pagenum'><a name="Page_3" id="Page_3">[3]</a></span>transportation project may be clearly understood.</p>
+
+
+<p class="sectionh">General Plan for Traffic Facilities at New York.</p>
+
+<p>The component elements of the general plan outlined by the late
+A.&nbsp;J. Cassatt, President, in his open letter to the Board of Rapid
+Transit Railroad Commissioners of the City of New York, dated
+January 18th, 1906, are indicated on <a href="#fig_1">Fig. 1</a>, and may be briefly summarized
+as follows:</p>
+
+<p><i>1.</i>&mdash;The Pennsylvania Tunnel and Terminal Railroad, generally
+referred to as the New York Tunnel Extension of the Pennsylvania
+Railroad. This line begins near Newark, N.&nbsp;J., crosses the Hackensack
+Meadows, and passes through Bergen Hill and under the North River,
+the Borough of Manhattan, and the East River to the large terminal
+yard, known as Sunnyside Yard, in Long Island City, Borough of
+Queens, New York. The line will be more fully described elsewhere.</p>
+
+<p><i>2.</i>&mdash;The electrification of the Long Island Railroad within the city
+limits.</p>
+
+<p><i>3.</i>&mdash;The Pennsylvania freight terminal yard and piers at Greenville,
+N.&nbsp;J., connecting by ferry with the Bay Ridge terminal of the Long
+Island Railroad.</p>
+
+<p><i>4.</i>&mdash;The Bay Ridge Improvement of the Long Island Railroad from
+East New York to Bay Ridge.</p>
+
+<p><i>5.</i>&mdash;Yards for increasing the freight facilities in the Boroughs of
+Brooklyn and Queens.</p>
+
+<p><i>6.</i>&mdash;The Atlantic Avenue Improvement in Brooklyn, involving the
+removal of the steam railroad surface tracks and the extensive improvement
+of the passenger and freight station at Flatbush Avenue.</p>
+
+<p><i>7.</i>&mdash;The New York Connecting Railroad, extending through a part
+of the Borough of Queens and crossing the East River by a bridge at
+Ward's and Randall's Islands to Port Morris, N.&nbsp;Y.</p>
+
+<p><i>8.</i>&mdash;The Glendale Cut-Off of the Long Island Railroad.</p>
+
+<p><i>9.</i>&mdash;New piers and docks in Newtown Creek at its confluence with
+the East River.</p>
+
+<p><i>10.</i>&mdash;Electrification of the United Railroads of New Jersey Division
+from Newark to Jersey City.</p>
+
+<p>The parts sustained by these elements in the work of transportation
+and distribution are briefly as follows:</p>
+
+<p>The New York Tunnel Extension is essentially a passenger line,
+although the Company has not only the legal powers but also the<span class='pagenum'><a name="Page_4" id="Page_4">[4]</a></span>
+facilities for making it a through route for freight if desired. It will
+transport passengers to and from the centrally located station at 33d
+Street and Seventh Avenue in New York City, joining the Long Island
+System at Sunnyside Yard, and, by means of the New York Connecting
+Railroad, it will form a link in the through traffic line, connecting
+the whole Pennsylvania System with the New England States. This
+line has been designed for the safe and expeditious handling of a large
+volume of traffic. The requirements include handling the heaviest
+through express trains south and west from the main line as well as
+the frequent and lighter local-service trains. For through service the
+locomotive principle of operation has been adhered to, that is, electric
+locomotives will take up the work of the steam locomotives at the interchange
+yard at Harrison, N.&nbsp;J., and, for excursion and suburban
+service to nearby towns, provision will be made for electric locomotives,
+or by operation of special self-propelled motor cars in trains, the project
+being planned to give the greatest flexibility in method of operation to
+meet the growing demand in the best way.</p>
+
+<p>The New York Connecting Railroad has important functions both
+for freight and passenger service. When constructed it will be about
+12 miles long, and will form a part of the line to the New England
+States for through passenger and freight service, and also carry local
+freight to and from Sunnyside Yard and Brooklyn, and all points on
+Long Island. By means of this line it will be possible to make the
+Brooklyn station at Flatbush Avenue a station on the through System
+for New England as well as the Western States.</p>

+
+<p>The initial equipment of the Western Division of the Long Island
+Railroad for electric traction has been made in advance of the opening of
+the tunnel line in order to take care of the requirements of the Atlantic
+Avenue improvement. This improvement involved the elimination
+of grade crossings within the City of Brooklyn and the conversion of
+the railroad line which was previously on the surface of the streets to
+part subway and part elevated line from the Flatbush Avenue Terminal
+to East New York Station, a distance of 5-1/4 miles. One of the requirements
+of this improvement was that the motive power should be
+changed to some form of power not involving combustion. This led
+to the adoption of electricity, and, in order to meet operating necessities,
+involved the electrification of connecting lines beyond the improvement
+proper, so that local service could be handled to the end of the<span class='pagenum'><a name="Page_6" id="Page_6">[6]</a></span>
+runs without changing the motive power. The extent of the electrification
+thus required was found to be about 100 single-track miles.
+This extensive electrification work was undertaken and completed in
+the summer of 1905, upon the completion of the Atlantic Avenue
+improvement proper, and since that time has been in successful operation.
+On the near approach of the construction of the New York
+Terminal improvement, plans for additional electrification on the Long
+Island Railroad were made, and the work is now in progress on the
+extensive additions required to couple up the tunnel extension with
+the various lines centering at the Long Island City terminus.</p>
+
+<p>The Bay Ridge Improvement of the Long Island Railroad comprises
+the readjustment of the right of way and the establishment of new
+grades in order to do away with grade crossings from the freight
+terminal at Bay Ridge to a junction with the New York Connecting
+Railroad at East New York, a distance of 10.4 miles. It also provides
+for the re-location of the line and the elimination of grade crossings
+on the branch running to Manhattan Beach, a distance of 3.7 miles.
+The work is being executed without interrupting traffic, and in all
+about 75 grade crossings will be abolished. This improvement became
+necessary in order to provide for the rapid extension of population into
+the suburban districts and for the present and future requirements of
+the section, to establish municipal conveniences and facilities, and
+to open additional streets across the right of way. To accomplish
+these ends, the line has been built in cuts and on embankments, there
+being about 6.4 miles of the former, 3.3 miles of the latter, and a
+tunnel, 3,500 ft. long, where the line crosses the Atlantic Avenue
+improvement.</p>
+
+<p>The Atlantic Avenue improvement, as mentioned above, involved
+the removal of the railroad tracks from the street surface for a distance
+of about 5-1/4 miles. This was done by constructing a series of elevated
+and subway structures, there being about 2.1 miles of the former, 2.4
+miles of the latter, and 0.8 mile of approaches, eliminating more than
+90 grade crossings. In the light of recent developments, it may be of
+interest to note that one of the reasons for establishing a combination
+elevated and subway line was that, at the time the improvement was
+projected, no underground railroad in the country, of similar length
+and carrying a heavy volume of local traffic, was operated by electricity,
+and public sentiment was against the operation of the entire length of<span class='pagenum'><a name="Page_7" id="Page_7">[7]</a></span>
+the line underground by steam power. This improvement also provided
+for depressing the entire Flatbush Avenue station and a freight
+yard. As the work progressed, the original plans for the station were
+greatly enlarged, the remodeled station covering about 61 city lots.</p>
+
+<p>The main point of passenger distribution is the New York station.
+Other important stations will be Flatbush Avenue, Brooklyn; Jamaica,
+Long Island, where the changes to and from electric motive power will
+be made; and Newark, N.&nbsp;J. Many other places, including the seaside
+resorts on Long Island and in New Jersey, will feel the benefits
+of the direct tunnel railroad into and through New York City. The
+Glendale Cut-Off will materially shorten the route and running time
+from New York through the tunnels to Rockaway Beach.</p>
+
+<p>The plans contemplate that passengers to and from the lower part
+of Manhattan will be carried by the steam line between Newark and
+Jersey City and cross the North River by ferry or the Cortlandt Street
+tunnels of the Hudson Company. Eventually, the old main line will
+be electrified and supersede the steam service between Newark and
+Jersey City.</p>
+
+<p>The Greenville Yard is the most important point for the receipt,
+transmission, and distribution of freight. From this point freight can
+be transported, without breaking bulk, by a comparatively short car-ferry
+to the Long Island Railroad terminus at Bay Ridge, and thus a
+very large part of the Pennsylvania Railroad Company's floatage in
+New York Harbor and the East River will be abolished, the floatage
+distance being reduced in the case of the New England freight from
+about 12 to 3 miles. This traffic will be routed from Bay Ridge <i>via</i>
+the Long Island Railroad to a connection with and thence over the
+New York Connecting Railroad to the New York, New Haven and
+Hartford Railroad at Port Morris, N.&nbsp;Y.</p>
+
+<p>As the facilities for the handling of freight in the Boroughs of
+Brooklyn and Queens had become insufficient for taking care of the
+prospective traffic, eleven new local delivery yards, having a combined
+area of about 2,153 city lots, have been established, and three existing
+yards are to be improved and enlarged so as to give a combined area
+of about 687 city lots. Of these new yards, the Bay Ridge freight
+terminal, containing about 790 city lots, is the largest; its functions
+have been described above. There is a freight terminal at East New
+York 200 ft. wide and a mile long, containing about 566 city lots,<span class='pagenum'><a name="Page_8" id="Page_8">[8]</a></span>
+which will be the distributing point of freight for the entire East New
+York section. This yard is depressed, and will be crossed by six viaducts
+carrying city streets. The North Shore freight yard, containing
+109 city lots, is connected with the Montauk Division by an overhead
+construction, known as the Montauk Freight Cut-Off, whereby all
+freight traffic to Jamaica may be kept out of the way of the Jamaica
+passenger traffic from the tunnels.</p>
+
+<p>It may be of interest to indicate briefly how much has already
+been accomplished in the execution of this general plan, and what still
+remains to be done for its completion.</p>
+
+<p>The larger part of the electrification of the Long Island Railroad
+and the elimination of grade crossings within the built-up city limits,
+the Atlantic Avenue improvement, and the yard and piers at Greenville,
+have been completed. The Sunnyside Yard and the Glendale Cut-Off
+will be completed during the next twelve months. On the Tunnel and
+Terminal Railroad the embankment and bridge work across the Hackensack
+Meadows and all the tunnels and excavation from the west side
+of Bergen Hill to Long Island City, except a short section near the
+eastern end of the line, have been completed. The New York station and
+other buildings and facilities connected therewith are well advanced.
+The laying of the track, the electrification of the line, and the installation
+of the signaling and lighting systems are under way. It is
+anticipated that the line will be ready for operation in the spring of
+1910.</p>
+
+<p>Report has been made to the Public Service Commission that a
+large part of the right of way for the New York Connecting Railroad
+has been obtained, and more than $3,000,000 has been spent by this
+railroad. The piers and docks at Newtown Creek and the electrification
+of the line from Newark to Jersey City are not yet actively under
+way.</p>
+
+
+<p class="sectionh">Estimated Cost of the Improvements.</p>
+
+<p>As appears from the foregoing statement, only parts of the improvements
+contemplated in the general scheme have been completed, others
+are in progress, and others have not yet been commenced. It is therefore
+impossible at the present time to make a close estimate of the
+total expenditure involved in the execution of the entire scheme. The
+following estimate of the cost of the Pennsylvania Railroad Company's<span class='pagenum'><a name="Page_9" id="Page_9">[9]</a></span>
+improvements in the New York District when fully completed is based
+on the best information now available:</p>

+<p class="sectionh">Corporate Organization and Franchise Conditions.</p>
+
+<p>As the tunnel extension lies partly in the State of New Jersey and
+partly in the State of New York, it was necessary to charter two companies,
+each covering the territory within the State to which it
+belonged. The New Jersey corporation was entitled the Pennsylvania,
+New Jersey and New York Railroad Company, and the New York
+corporation, the Pennsylvania, New York and Long Island Railroad
+Company. These organizations were completed early in 1902. Subsequently,
+after the tunnels had been joined under the North River, the
+companies were consolidated, on June 26th, 1907, and thereby formed
+the present company under the name of the Pennsylvania Tunnel and
+Terminal Railroad Company, a corporation of both States.</p>
+
+<p>Mr. Cassatt, President of the Pennsylvania, New York and Long
+Island Railroad Company, made application in its behalf for a franchise
+to extend the lines of the Pennsylvania Railroad by tunnels
+under the North River to a passenger station to be erected in New<span class='pagenum'><a name="Page_10" id="Page_10">[10]</a></span>
+York City and thence under the East River to a connection with the
+Long Island Railroad, on May 5th, 1902.</p>
+
+<p>The franchise for that part of the tunnel line which is within
+the State of New York, that is, from the boundary line between New
+York and New Jersey, in the Hudson River, to the eastern terminus
+at Sunnyside Yard, Long Island, is contained in the certificate issued
+by the Board of Rapid Transit Railroad Commissioners of the City
+of New York on October 9th, 1902.</p>
+
+<p>The essential features of the franchise have been summarized substantially
+as follows in the report of the Committee of the Board of
+Rapid Transit Railroad Commissioners of the City of New York,
+dated June 14th, 1902:</p>
+
+<p><i>First.</i>&mdash;A grant by the city in perpetuity of rights, subject, however,
+to a periodic readjustment of payments at intervals of twenty-five

+support safely any structures superimposed or which may hereafter be
+superimposed thereon by the city or under public authority.</p>
+
+<p><i>Sixteenth.</i>&mdash;The company to have the right to convey or mortgage
+the franchise, but every grantee, whether directly or under a mortgage,
+to assume the obligations already assumed by the Railroad Company
+and the Railroad Company not to be relieved of such obligations by
+the grant.</p>
+
+<p>This franchise was passed by the Board of Aldermen on December
+16th and approved by the Mayor on December 23d, 1902.</p>
+
+<p>Subsequently, an agreement, dated June 21st, 1907, was entered
+into by the City of New York, the Tunnel Company, and the Long
+Island Railroad Company covering the construction of the Sunnyside
+Yard, which forms the eastern terminus of the line.<span class='pagenum'><a name="Page_14" id="Page_14">[14]</a></span></p>
+
+<p>In pursuance of this agreement, the map or plan of the City of
+New York was changed by discontinuing or closing portions of fifty
+streets or avenues, and by changing the grades of sixteen streets or
+avenues, in the Borough of Queens, and the portions of streets and
+avenues thus discontinued and closed, most of which were not opened
+for public use, were sold to the Railroad Companies. The agreement,
+however, reserved to the City permanent and perpetual underground
+rights and easements to maintain in a reasonable manner, not inconsistent
+with the construction and operation of the railroad facilities
+of the Companies, its existing sewers, drains, and other sub-surface
+structures in, under, and through the lands within the lines of the
+discontinued portions of each of such streets and avenues, including
+the right to repair, rebuild, and enlarge the same, and to construct in a
+reasonable manner, not inconsistent with the construction and operation
+of the railroad facilities of the Companies, such additional sewers
+or drains in, under, or through the lands as may be hereafter required
+by the City, together with the right to enter upon the premises from
+time to time as may be necessary for the purpose of inspecting, repairing,
+constructing, or rebuilding the sub-surface structures.</p>
+
+<p>The agreement required the Companies to construct at their expense,
+four viaducts or bridges over their tracks and terminal development,
+three with roadways 42 ft. wide, one with a roadway 60 ft. wide,
+and each to have two sidewalks 10 ft. wide, the work to include the
+paving of the roadways and sidewalks.</p>
+
+<p>The Companies are further required to pay one-half the cost of the
+construction of the foundations, abutments, piers, superstructures, and
+approach of an additional viaduct or bridge over the Sunnyside Yard,
+to have a roadway not more than 60 ft. wide and two sidewalks each
+10 ft. wide, and to grant the City of New York a perpetual easement
+for the continuance of the same in the location upon which it shall be
+constructed.</p>
+
+<p>The agreement further provides that the Companies shall not injure
+the sewers or other substructures now existing or hereafter constructed
+under the streets and avenues, and, in case of injury, that they shall
+repair them or pay the cost thereof; that the viaducts shall be completed
+within the shortest time consistent with their safe and proper
+construction, and that during their construction temporary streets shall
+be provided for the accommodation of traffic.<span class='pagenum'><a name="Page_15" id="Page_15">[15]</a></span></p>
+
+<p>The Companies are required to bear all the expense of changes of
+grade in the streets and avenues, except those made necessary by the
+construction of the viaduct or bridge to be paid for in part by the
+City; to indemnify the City against all liability for any and all damages
+which may accrue on account of any street which may be closed
+or the grades of which may be changed in pursuance of the agreement;
+to assume all liabilities by reason of the construction or operation of
+the railroads, or the construction of the viaducts, and to save the city
+harmless from any liability whatever, to either persons or property, by
+reason of the construction or operation of the railroads or the construction
+of the viaducts.</p>
+
+<p>The Companies are also required to indemnify the City against and
+pay the cost of all alterations which may be required to the sewerage or
+drainage system or to any sub-surface structures and pipes laid in the
+streets or avenues on account of the construction and operation of the
+terminal, passenger yard, or freight yard of the Companies, or on
+account of the changes in grades or street system.</p>
+
+<p>The Companies are authorized, if they deem it necessary to the construction
+or to the efficient operation of the terminal passenger yard or
+freight yard, to depress, at their expense, any pipes or other sub-surface
+structures now under the surface of any of the portions of the streets
+or avenues discontinued or closed, or to elevate and carry the same
+upon any of the viaducts or bridges, the plans of such depression or
+elevation to be approved by the Board of Estimate and Apportionment.</p>
+
+<p>All works within, upon, or over the public streets and avenues are
+subject to the supervision and inspection of the proper municipal officer
+or officers, under such regulations as he or they may determine and be
+authorized by law to impose; and the plans for the construction of
+viaducts or bridges are to be approved by the Board of Estimate and
+Apportionment.</p>
+
+<p>The Companies are required to cede to the City of New York
+perpetual easements for the right to continue and maintain the viaducts
+or bridges over the streets and avenues, sufficient for their control by
+the City for the purpose of police regulation and other control contemplated
+by the City ordinances for the case of streets or highways;
+reserving, however, the right to construct and maintain, at their own
+expense, such connections between the viaducts or bridges and their<span class='pagenum'><a name="Page_16" id="Page_16">[16]</a></span>
+property as shall not interfere with the use of the viaducts or bridges
+for street purposes.</p>
+
+<p>The Companies are also required to cede to the City, grade and
+curb, portions of five existing or proposed streets or avenues, and to
+pave portions of two other avenues.</p>

+as heretofore stated, constitute the Pennsylvania Tunnel and Terminal
+Railroad Company.</p>
+
+
+<p class="sectionh">Engineering Organization.</p>
+
+<p>Mr. Rea, Vice-President, has general charge of all matters involved
+in the designing and execution of the project.</p>
+
+<p><i>The Board of Engineers.</i>&mdash;Before the beginning of the work, the
+Management appointed a Board of Engineers which was instructed
+to examine into the New York Tunnel Extension project; to pass upon
+the practicability of the undertaking; to determine upon the best plans
+for carrying it out; to make a careful estimate of its cost; and, if the
+work was undertaken, to exercise general supervision over its
+construction.</p>
+
+<p>President Cassatt's letter appointing the Board contains the following
+further instructions:</p>
+
+<p>"You are requested to procure all additional information that may
+be needed, sparing neither time nor any necessary expense in doing
+so, for I am sure it is not necessary for me to say that, in view of the
+magnitude and great cost of the proposed construction, and of the<span class='pagenum'><a name="Page_17" id="Page_17">[17]</a></span>
+novel engineering questions involved, your studies should be thorough
+and exhaustive, and should be based upon absolute knowledge of the
+conditions."</p>
+
+<p>The Board was organized on January 11th, 1902, when it held
+its first session, and continued in the performance of its duties until
+April 30th, 1909, when it was dissolved, its work having been completed.</p>
+
+<p>The Board held regular and special sessions to receive progress
+reports from the Chief Engineers in direct charge of construction, and
+to consider questions relating to the plans and details of the work
+submitted by its members or referred to it by the Management. It
+then reported its conclusions to the Vice-President for approval before
+the work was undertaken.</p>
+
+<p>The Management earnestly impressed upon the Board throughout
+the whole period of its labors, that the Tunnel Extension and facilities
+were to be designed and constructed without regarding cost as a
+governing factor, the main considerations being safety, durability,
+and proper accommodation of the traffic. No expenditure tending to
+insure these conditions was to be avoided.</p>
+
+<p>The Board, when organized, was composed as follows: Col. Charles
+W. Raymond, Corps of Engineers, U.&nbsp;S. Army, Chairman; Messrs.
+Gustav Lindenthal, Charles M. Jacobs, Alfred Noble, and William H.
+Brown.</p>
+
+<p>Mr. George Gibbs was appointed a member of the Board on April
+9th, 1902. Mr. Lindenthal resigned on December 15th, 1903, and Mr.
+Brown resigned on March 1st, 1906. Mr. Rea and all the members of
+the Board are members of the American Society of Civil Engineers,
+and Mr. Noble is a Past-President of the Society.</p>
+
+<p>Mr. William R. Mead, of the firm of McKim, Mead, and White,
+Architects for the Terminal Station, was associated with the Board
+for the consideration of architectural subjects.</p>
+
+<p>Mr. Robert H. Groff, Secretary of the Company, was also Secretary
+of the Board until his resignation on January 31st, 1907. Mr. William
+Couper was Acting-Secretary from April 15th, 1907, to April 30th,
+1909.</p>
+
+<p>S. Johannesson, Assoc. M. Am. Soc. C.&nbsp;E., was Engineer Assistant
+to the Chairman from December 1st, 1905, to April 30th, 1909.</p>
+
+<p><i>Division of the Work.</i>&mdash;For the purposes of actual construction, the
+line was divided into four parts: the Meadows Division, the North<span class='pagenum'><a name="Page_18" id="Page_18">[18]</a></span>
+River Division, the Terminal Station, and the East River Division. A
+chief engineer appointed by the Management had charge of the construction
+of each Division. The chief engineers exercised full authority
+in the organization of the working forces, and in the general conduct
+and management of the work of construction on their respective Divisions,
+in accordance with the plans for such work approved by the
+Board of Engineers and the Management.</p>
+
+<p>Architects were employed to design the Terminal Station building
+and superintend its erection; and structural engineers to design and
+erect steel structures and facilities, and carry on the work under the
+direction of a Chief Engineer of the Company.</p>
+
+<p>Committees, consisting principally of officers of the Pennsylvania
+Railroad Company, co-operating with the regular engineering organization,
+were appointed to consider the operating features of the project,
+so that the experience of the Pennsylvania Railroad Company's organization
+might be utilized in the work.</p>

+
+<p>The following summary description of the various divisions of the
+line is intended to give a comprehensive idea of the general features
+of the project. Full details will be given in succeeding papers. The
+line and its respective divisions are shown on <a href="#plate1">Plate I</a>.</p>
+
+<p><i>Meadows Division.</i>&mdash;Chief Engineer until March 1st, 1906, Mr.
+William H. Brown, Chief Engineer, Pennsylvania Railroad Company,
+when he retired from active service with the latter Company; since
+March 1st, 1906, Mr. Alexander C. Shand, Chief Engineer, Pennsylvania
+Railroad Company.</p>
+
+<p>This Division consists of an "interchange yard" at Harrison, near
+Newark, N.&nbsp;J., adjoining the tracks of the present New York Division
+of the Pennsylvania Railroad, and a double-track railroad across the
+Hackensack Meadows to the west side of Bergen Hill, a distance of
+6.04 miles. The construction is embankment and bridge work, including
+bridges across the Pennsylvania, Erie, and Lackawanna Railroads,
+and the Hackensack River.</p>
+
+<p><i>North River Division.</i>&mdash;Chief Engineer, Mr. Charles M. Jacobs.</p>
+
+<p>This Division commences at the west side of Bergen Hill and
+passes through the hill in two single-track rock tunnels to a large permanent
+shaft at Weehawken, near the west shore of the North River,<span class='pagenum'><a name="Page_19" id="Page_19">[19]</a></span>
+and thence eastward a distance of 224 ft. to the Weehawken shield-chamber.
+It then passes under the river through two cast-iron, concrete-lined,
+single-track tunnels, with outside diameters of 23 ft., to
+a point under 32d Street, near Eleventh Avenue, in New York City,
+and thence through two single-track tunnels of varying cross-section,
+partly constructed in cut-and-cover, to the east side of Tenth Avenue.
+It then passes into the Station Yard and terminates at the east building
+line of Ninth Avenue. The work included the Station Yard excavation
+and walls from Tenth Avenue to Ninth Avenue, and the retaining
+walls and temporary underpinning of Ninth Avenue. The aggregate
+length of the line in this Division is 2.76 miles.</p>
+
+<p><i>New York Station and Approaches.</i>&mdash;Mr. George Gibbs, Chief Engineer
+of Electric Traction and Station Construction.</p>
+
+<p>The Station and its approaches extend from the east line of Tenth
+Avenue eastward to points in 32d Street and 33d Street, respectively,
+292 ft. and 502 ft. east of the west line of Seventh Avenue. This
+Division included the construction of subways and bridges for the
+support of 31st and 33d Streets and Seventh, Eighth, and Ninth Avenues,
+the Station building between Seventh and Eighth Avenues, the
+foundations for the post office to be erected west of Eighth Avenue, the
+service power-house in 31st Street between Seventh and Eighth Avenues,
+the power-house in Long Island City, the traction system, tracks,
+signals, and miscellaneous facilities required in the physical construction
+of the entire terminal railroad ready for operation. Messrs.
+McKim, Mead, and White were the architects for the Station and
+Messrs. Westinghouse, Church, Kerr and Company executed the structural
+engineering work, both in the station and for the support of the
+streets, as well as the construction of the subways.</p>
+
+<p>The station is of steel skeleton construction with masonry curtain
+walls, all supported by a system of columns extending to a rock foundation.
+This building covers two city blocks and one intersecting street,
+and has an area of about 8 acres. It is 774 ft. long, 433 ft. wide, with
+an average height above the street of 69 ft., and a maximum of 153 ft.
+The main waiting-room is 277 ft. long, 103 ft. wide and 150 ft. high.
+The Concourse is 340 ft. long and 210 ft. wide.</p>
+
+<p>The level of the track system below the street surface varies from
+39 to 58 ft., and is from 7 to 10 ft. below mean high water in the
+harbor, thereby necessitating the establishment of an elaborate system<span class='pagenum'><a name="Page_20" id="Page_20">[20]</a></span>
+of drainage over the entire station yard area. Access to the street is
+gained by elevators and stairways.</p>
+
+<p>To accelerate the loading and unloading of the trains, high platforms
+will be constructed in the station on a level with the floors of
+the cars, in order to avoid the use of car steps and increase the traffic
+capacity of the station.</p>
+
+<p>There will be 21 standing-tracks at the station, and 11 passenger
+platforms, providing 21,500 ft. of platform adjacent to passenger trains.
+Within the station area, which from Tenth Avenue to the normal
+tunnel sections east of Seventh Avenue comprises 28 acres, there will
+be a total of about 16 miles of track.</p>
+
+<p>The service plant for the installation of machinery for lighting,
+heating, and ventilating the station, and for operating the interlocking
+system, is located in an independent building south of the station.</p>
+
+<p>The Power-House to supply the electrical energy for the operation
+of the tunnel line and the Long Island Railroad is situated on property
+in Queens Borough adjoining the present Long Island Railroad Station
+near the East River, and was constructed under the Chief Engineer
+of Electric Traction and Station Construction. As at present designed,
+the dimensions of the structure are 200 ft. by 262 ft., outside measurement.
+It can accommodate six generating units of 5,500 kw., the
+standard adopted for future work, and two of 2,500 kw. for lighting
+the tunnels. The ultimate capacity of this station when extended will
+be about 105,000 kw.</p>
+
+<p><i>East River Division.</i>&mdash;Chief Engineer, Mr. Alfred Noble.</p>
+
+<p>This Division begins at the eastern limits of the New York Station
+at a point in 32d Street, 292 ft. east of the west line of Seventh Avenue,
+and at a point in 33d Street, 502 ft. east of the west line of Seventh
+Avenue, and also includes the excavation work and retaining walls for
+the station site and yard, to the track level, westward to Ninth Avenue.
+It extends eastward from the station under 32d and 33d Streets through
+tunnels partly three-track and partly so-called twin tunnels to Second
+Avenue; thence the line curves to the left under private property to
+permanent shafts a few feet east of First Avenue. Four single-track,
+cast-iron, concrete-lined tunnels, with outside diameters of 23 ft., pass
+under the East River, and, after passing through permanent shafts
+near the bulkhead line, reach the surface in Long Island City from
+3,000 to 4,200 ft. east of the East River. The tunnel portals are in<span class='pagenum'><a name="Page_21" id="Page_21">[21]</a></span>
+Sunnyside Yard, which extends to Woodside, the easterly end of the
+Division, and the Yard grading with its buildings and a number of
+City viaducts crossing it were executed under this Division. The
+total length of the Division is 4.48 miles.</p>
+
+<p>The total length of the entire line is 13.66 miles. There are 6.78
+miles of single-track tube tunnels, and the average length of the tunnels
+between portals is 5.56 miles.</p>

+
+<p class="sectionh">General Considerations.</p>
+
+<p>Details have been omitted from the foregoing description, as they
+can be treated better and more fully by the constructing engineers in
+succeeding papers. There are, however, some general considerations
+involved in the designing of the work, which may, perhaps, be referred
+to more conveniently in this introductory paper, and these will now
+receive attention.</p>
+
+<p>In all parts of the work problems were encountered requiring for
+their solution large expenditures and much engineering skill; but many
+of these difficulties had been frequently met in previous engineering
+experience, and the methods of overcoming them were well understood.
+Thus, in the Meadows Division, a long and heavy embankment, part
+of which was on submerged meadow land, and many bridge foundations
+had to be constructed; in the Bergen Hill tunnels, very tough
+trap rock was encountered; in the tunnels under the city, the work was
+much complicated and its cost increased greatly by the necessity of
+caring for sewers, water and gas pipes, and the foundations of adjacent
+buildings; and many troublesome problems were met in the construction
+of the tunnels connecting the East River tunnels with the Sunnyside
+Yard.</p>
+
+<p>The novel features of the project, however, were the great tunnels
+extending the line under the North and East Rivers. Tunnels of the
+kind contemplated, to be used for heavy and rapid railroad traffic, had
+never been constructed through materials similar to those forming the
+beds of the North and East Rivers. Questions arising in connection
+with the design and method of construction of the tunnels will be
+considered later. Here they are referred to only in their relation to
+the location and grades of the line, in which connection the conditions
+controlling their establishment were the most important elements.</p>
+
+<p><i>Location and Grades.</i>&mdash;It was desirable to make the tunnels between<span class='pagenum'><a name="Page_22" id="Page_22">[22]</a></span>
+the bulkhead lines of the rivers as straight as possible, and it was
+necessary to place them at sufficient depth below the dredging plane
+of the War Department (which in the North and East Rivers is 40
+and 26 ft. below mean low water, respectively) to insure them against
+possible injury from heavy anchors or sunken vessels. Furthermore,
+they had to pass under the piers and bulkheads of Manhattan at a
+depth sufficient to make it certain that they would not affect the
+stability of those structures. Another consideration influencing the
+establishment of the depth of the tunnels below the bottoms of the
+rivers became important as soon as the method of construction by
+shields with compressed air was adopted, namely, the necessity of
+providing sufficient cover to guard, as far as possible, against blow-outs
+during construction.</p>
+
+<p>The tunnels under the city, connecting the sub-river tunnels with
+the Terminal Station, were located so as to give as favorable grades
+as possible. The provision of the franchise requiring the tops of the
+tunnels to be at least 19 ft. below the Street surface, which had been
+suggested by the Company to permit of future subways, had no effect
+on their location, as other conditions required them to be at a greater
+depth.</p>
+
+<p>The line extending westward from Bergen Hill had to be established
+so as to give ample head-room at the numerous bridges over
+the railroads and highways which it crosses.</p>
+
+<p>Eastward from the East River tunnels, the grades were established
+so as to rise as uniformly as possible to the level of the Sunnyside Yard.</p>
+
+<p>The general features of the line, as finally adopted and constructed,
+are as follows:</p>
+
+<p>The maximum grade west of the Terminal Station occurs on the
+New York side of the North River, and is 2% in the west-bound and
+1.93% in the east-bound tunnels. The ruling grades (for the ascending
+traffic) being 1.32% in the west-bound and 1.93% in the east-bound
+tunnels. In the tunnels east of the Terminal Station the ruling grade
+is 1.5% for both east-bound and west-bound traffic. There is, however,
+descending with the traffic, a short section on a grade of 1.9 per cent.
+These grades would be objectionable with steam locomotives under a
+heavy traffic, but the development of the electric locomotive has rendered
+possible the operation of grades which would have formerly been
+considered prohibitive.<span class='pagenum'><a name="Page_23" id="Page_23">[23]</a></span></p>
+
+<p>From the junction with the Pennsylvania Railroad, near Harrison,
+N.&nbsp;J., to Woodside, Long Island, a distance of 13.66 miles, there is an
+average of 1.5 curves per mile; the line having a total curvature of
+230 degrees. The maximum curvature is 2 degrees.</p>

+
+<p><i>Method of Construction of Sub-River Tunnels.</i>&mdash;The character of
+the material through which the tunnels were to be constructed differed
+greatly in the two rivers. The bed of the North River, at the level
+of the tunnels, consists of silt composed principally of clay, sand, and
+water, while that of the East River is formed of a great variety of
+materials, such as quicksand, sand, boulders, gravel, clay, and bed-rock.
+When the method of construction had to be decided there were no
+thoroughly satisfactory precedents to follow in the case of either river,
+although the Gas Tunnel under the East River, the partly constructed
+Hudson Tunnels under the North River, the St. Clair Tunnel under
+the St. Clair River, the Blackwall and several other tunnels under the
+Thames River at London, supplied much useful information. The
+smaller tunnels for a lighter traffic, since so successfully constructed
+under the North and East Rivers, had not then been completed. Under
+these circumstances, it was the desire of the Management that the
+Board should receive and consider proposed methods of construction
+from all available sources; and during the first year of its labors much
+of its time was devoted to the examination and discussion of projects
+submitted for its consideration by engineers and practical builders,
+some of these projects having decided merit. Most of the methods
+proposed involved temporary structures, or the use of floating plant,
+in the navigable channels of the river. This was objectionable in view
+of the resulting obstruction to the enormous river traffic. After full
+consideration of the subject, it was decided to adopt the shield method
+with compressed air for the construction of the tunnels under both
+rivers, this being the only method recommended by the Chief Engineers,
+and having the great advantage of conducting all operations below
+the bottom of the river, thus avoiding obstruction of the channel.</p>
+
+<p>Experience has shown, as was anticipated, that it is much more
+difficult to construct tunnels in such material as occurs in the East
+River and on the New Jersey side of the North River, than in more
+homogeneous material such as is found in the greater part of the
+North River. During the progress of construction under the East
+River, there were frequent blow-outs through fissures opened in the<span class='pagenum'><a name="Page_24" id="Page_24">[24]</a></span>
+river-bed, and the bottom of the river over the tunnel had to be
+blanketed continuously with clay, to check the flow of the escaping air.</p>
+
+<p>In view of the serious difficulties which it was thought might be
+encountered in the application of the shield method to the East River
+work, other methods for the execution of this part of the project
+received special consideration, one of the methods considered being the
+freezing process. It was proposed to drive a small pilot tunnel and
+freeze the ground for a sufficient distance around it by circulating
+brine through a system of pipes established in the tunnel. The pilot
+tunnel was then to be removed and the full-sized tunnel was to be
+excavated in the frozen material and its lining placed in position. By
+this means, it was intended to avoid the danger incident to the use of
+compressed air in material of greatly varying character. This method
+contained too many elements of uncertainty to justify its adoption; but
+as the Management considered it desirable to have, if possible, an
+alternative method, an extended experiment was made with the freezing
+process. A pilot tunnel, 7 ft. 6 in. in diameter, was driven in the bed
+of the East River for a distance of 160 ft., circulating pipes were
+established in it, and brine at a very low temperature was passed
+through the pipes until the ground was frozen for a distance of about
+11.5 ft. around the tunnel. Observations to determine the rate of cooling
+and other important points connected with the process were carefully
+made. When it was found that the construction of the tunnels was
+progressing satisfactorily by the shield method, and that so much time
+was required to freeze the material that the freezing process could not
+be used to advantage in this particular case, the experiment was discontinued.</p>
+
+<p><i>Design of the Sub-River Tunnels.</i>&mdash;The sub-river tunnels consist of
+a circular cast-iron shell, of the segmental, bolted type, having an outside
+diameter of 23 ft., lined with concrete having a normal thickness
+of 2 ft. from the outside of the shell. Through each plate of the shell
+there is a small hole, closed with a screw plug, through which grout
+may be forced into the surrounding material. Each tunnel contains
+a single track. A concrete bench, the upper surface of which is 1 ft.
+below the axis of the tunnel, is placed on each side of the track, the
+distance between benches being 11 ft. 8 in. These benches contain
+ducts for carrying electric cables. The main reason for adopting single-track
+tunnels instead of a larger tunnel containing two tracks was to<span class='pagenum'><a name="Page_25" id="Page_25">[25]</a></span>
+avoid the danger of accidents due to the obstruction of both tracks
+by derailment or otherwise. The tunnels are made just large enough
+to allow the passage of a train with perfect safety, as it was believed
+that with such an arrangement thorough ventilation would be secured
+by the motion of the trains. Experience seems to justify this assumption,
+but, in order to assure thorough ventilation under unusual conditions,
+such as the stoppage of trains in the tunnels, a complete
+ventilating plant will be provided for each tunnel. The rapidity and
+safety of construction were increased by making the tunnel as small
+as possible, one of the difficulties in the shield method of construction
+being the difference in hydrostatic pressure between the top and bottom
+of the shield, which increases with the diameter of the tunnel.</p>
+
+<p>The concrete lining was introduced to insure the permanency of
+the structure, strengthen it from outward pressure and guard it against
+injury from accidents which might occur in the tunnel. The side
+concrete benches were suggested by Mr. Cassatt, President, to confine
+the trains to the center of the tunnels in case of derailment, and to
+furnish sidewalks on each side of the trains so as to obviate the necessity
+of walking on the track.</p>
+
+<p>Refuge niches are constructed in the side benches of the tunnels.
+Manholes, splicing chambers, pump chambers, and other features for
+the handling of the electric cables and drainage, are established at
+intervals.</p>
+
+<p>At points where unusual stresses were anticipated, as for instance
+where the tunnels pass from rock to soft ground, the shell was composed
+of steel instead of cast-iron plates. In the North River tunnels
+the concrete lining in the invert and in the arch was reinforced by
+longitudinal steel bars, but these were not introduced in the East River
+tunnels.</p>
+
+<p>Other details connected with the structures, including the drainage,
+lighting, ventilation, signaling, and electrification systems, will be
+given in succeeding papers.</p>
+
+<p><i>Stability of the Sub-River Tunnels.</i>&mdash;One of the most important
+questions connected with the design of these tunnels was their probable
+stability under the long-continued action of a heavy and rapid railroad
+traffic. The tunnels are lighter than the materials which they displace
+even when the weight of the heavy live load is included. In the East
+River the character of the material seemed to justify the conclusion<span class='pagenum'><a name="Page_26" id="Page_26">[26]</a></span>
+that the tunnels would not be displaced even under the action of the
+live load. In the North River, however, the tunnels are enveloped by
+a soft silt and it was at first apprehended that some system of supports
+would be advisable to carry the heavy traffic and insure the tunnels
+against displacement under its action. To meet this contingency, which
+was then believed to be a very serious one, it was proposed to sink cast-iron
+screw-piles through the bottom of each tunnel into and through
+the underlying silt until satisfactory bearing material was reached.
+The pile supports were worked out in sufficient detail to be embraced
+in the contract for the construction of these tunnels, with provision,
+however, for omitting them should it be determined subsequently that
+their use was undesirable. The contract plans contained provisions for
+sliding joints where the piles pass through the tunnel floor, so that the
+live load might be carried directly to the pile heads by a system of
+girders, and also for attaching the piles directly to the tunnel, the two
+plans being alternatives.</p>
+
+<p>Investigations, made during the progress of the work to determine
+the physical character of the silt and its action on the tunnels, suggested
+the possibility that the use of pile supports might be inadvisable.
+This view was confirmed by actual experience in the operation
+of the tunnels of the Hudson Companies between Hoboken, N.&nbsp;J., and
+Morton Street, Manhattan, which were opened to traffic in February,
+1908. The stability of these tunnels under traffic gave further assurance
+that supports were unnecessary under the North River tunnels of
+the Pennsylvania Railroad Company, and they were therefore dispensed
+with.</p>
+
+<p><i>Cross-Passages Between the Tunnels.</i>&mdash;The Bergen Hill tunnels,
+the land portions of the North River tunnels and the tunnels under
+Manhattan are connected by cross-passages at intervals varying from
+50 to 300 ft. As it was the desire of the Management to provide every
+arrangement possible to insure the safety of its passengers and employees
+and also to provide for the convenience of inspection, the question
+of establishing cross-passages between the tunnels under the rivers
+was given most careful consideration. The conclusion was finally
+reached that such passages as it was possible to construct between these
+tunnels might increase instead of diminish the danger in case of
+accident. No more cross-passages have therefore been constructed in
+the sub-river sections, except in the East River, where there is a cross-passage<span class='pagenum'><a name="Page_27" id="Page_27">[27]</a></span>
+and pump chamber combined between each pair of tunnels
+about 750 ft. from the Manhattan bulkhead line.</p>
+
+
+<p class="sectionh">Probable Results of the Improvements.</p>
+
+<p>In preceding pages reference has been made to the general objects
+of the improvements included in the project of the Pennsylvania Railroad
+Company for the New York District. While it is impossible, in
+this introductory paper, to analyze fully the transportation problem at
+New York, it seems desirable to indicate briefly some of the more
+obvious effects which the improvements may be expected to produce
+upon the distribution and handling of traffic.</p>
+
+<p>New York City owes its position as the business metropolis of the
+country mainly to its magnificent harbor and the extensive waterfronts
+on its deep, wide rivers, which furnish unrivaled facilities, at a short
+distance from the sea, for foreign and domestic water-borne commerce,
+its foreign commerce being about half the total for the whole country.
+The water-transportation facilities of the port and its tributaries, therefore,
+have always been guarded with jealous care, not only by the local
+commercial interests but also by the General Government.</p>
+
+<p>During recent years, however, the population of the metropolitan
+district has increased so enormously that New York is now the greatest
+terminal passenger and freight traffic center in the country; and in
+manufactures it ranks first among American cities. The new commercial
+interests thus created are of at least equal importance with
+those of the water-borne commerce, although their existence and development
+are largely the result of the water facilities of the port.</p>
+
+<p>The local passenger and freight traffic of the Pennsylvania and of
+other railroads reaching the west shore of the North River is conducted
+by car-floats and ferry-boats which deliver their loads at piers on the
+Manhattan waterfront and elsewhere in the harbor. These boats
+obstruct and endanger the free navigation of the channels and occupy
+space along the waterfront greatly needed for the accommodation of the
+long-distance water-borne commerce, especially on the North River.</p>
+
+<p>In the East River the importance of ferry-boats as a means of
+traffic distribution has already been greatly reduced by the construction
+of bridges and tunnels which provide for the greater part of the passenger
+and vehicular traffic. The North River, however, by reason of its
+greater width and the comparative slowness of its currents, is by far<span class='pagenum'><a name="Page_28" id="Page_28">[28]</a></span>
+the more important waterway for the use of ocean-going vessels of the
+larger classes. In this river the conditions for the construction of
+bridges, within the limits of commercial convenience, seem to be
+practically prohibitory. Tunnels, for the transportation of passengers
+and the diversion of the freight traffic from the inner waters of the
+harbor, are apparently the only available means of relief.</p>
+
+<p>When the new line is in operation, a very large part of the New
+York passenger traffic of the Pennsylvania Railroad will be carried
+to the New York Station at Seventh Avenue and 33d Street and the
+rest will go to Cortlandt Street through the Hudson Company's tunnels.
+Thus a large portion of the Pennsylvania passenger ferry traffic, which
+amounts to more than 91,000 passengers daily, will be practically
+eliminated from the water-transportation problem. In addition, a large
+part of the Long Island Railroad's passengers will use the station at
+Seventh Avenue and 33d Street, and its ferry traffic will be reduced
+accordingly.</p>
+
+<p>The new arrangements for the transfer of freight from Greenville
+to Bay Ridge will relieve the inner waters of the harbor of a large
+volume of obstructive car-float traffic. There appears to be no reason
+why this traffic should not be eventually conducted through tunnels
+under the outer harbor, should future transportation conditions justify
+the enormous cost of such structures.</p>
+
+<p>It is to be remarked that while these new arrangements greatly
+reduce the passenger and freight water transportation, they have no
+effect on the large vehicular traffic across the North River which must
+continue to be conducted by ferries until it can be otherwise provided
+for. As long as these conditions exist, ferry-boats must be used in
+large numbers and continue to obstruct the North River. This difficulty
+probably cannot be overcome by the construction of bridges, as
+in the case of the East River, but it does not seem too much to expect
+that, eventually, tunnels to provide for the vehicular traffic, like the
+Blackwall tunnel under the Thames, will be established under the
+North River.</p>
+
+<p>It would be interesting to estimate the increase in railroad traffic
+capacity resulting from these improvements, but the data required for
+this purpose are not available. Some idea of the increase in passenger
+traffic capacity resulting from the establishment of the tunnel line
+may be obtained by comparing the proposed daily train-movements for<span class='pagenum'><a name="Page_29" id="Page_29">[29]</a></span>
+the new station with the train-movements at other important railroad
+stations. The daily train-movements of six such stations are given
+in the following table:</p>

+</div>
+
+<p>The freight capacity of the Pennsylvania System at New York
+has been greatly enlarged by the construction of the Greenville Yard
+and the facilities connected therewith, but it is impossible to estimate
+the amount of this increase. However, it is worthy of remark that,
+during the period from 1900 to 1906, the freight traffic density on the
+directly-operated lines of the Pennsylvania Railroad Company increased
+from 3,268,330 to 4,742,081 ton-miles per mile of road, a
+growth of nearly 50 per cent. Doubtless the improved freight facilities
+of the New York District had a large influence in the development
+of this increase.</p>
+
+<p>One of the most interesting points connected with this development
+of traffic facilities is its influence on the relative distribution of population
+in the different parts of the metropolitan district. In 1907 the
+population per acre of the different divisions of Greater New York
+was reported as follows: Manhattan, 157; Brooklyn, 29; Bronx, 14;
+Queens, 3; Richmond, 2. The effect of new lines connecting some of
+these districts, and sections of New Jersey not far from the North
+River, with the business center of the city will undoubtedly be to
+increase greatly their population-density. It does not seem probable
+that the population-density of Manhattan will be sensibly reduced by
+these improvements, for they stimulate the increase of population, and
+apparently no increase of transportation facilities can keep up with
+the growth of the city. The population of a great commercial city
+must be congested near the business center. This is a necessary condition
+of its existence. All that can be done to meet this condition is to<span class='pagenum'><a name="Page_30" id="Page_30">[30]</a></span>
+provide all possible facilities for moving the people into and out of the
+business districts and within its limits.</p>
+
+<p>During recent years the business population of the lower part of
+the Borough of Manhattan has become greatly congested. Very high
+buildings, providing business accommodations for large numbers of
+people, have been constructed, and these people must move to and from
+their working places at about the same times, that is, at the "rush
+hours" in the morning and afternoon, at the beginning and ending of
+the working day. Every effort has been made to provide for this
+immense and rapidly increasing local passenger traffic, by the construction
+of surface, elevated, and subterranean railways; but the demand
+for transportation has increased much faster than the facilities can
+be provided, and it is evident that the limit of down-town passenger
+traffic facilities has been very nearly reached.</p>
+
+<p>Apparently, the only remedy for these conditions is the movement
+of business and the people transacting it up-town or to the Boroughs
+of Brooklyn and Queens, which are now readily accessible by tunnels
+and subways. This movement, of course, is resisted by the great real
+estate and money interests centered in the lower part of the city,
+but, notwithstanding this resistance, the improvement has commenced
+and has rapidly advanced. The great retail houses are being established
+above 23d Street; the banks and brokers' offices are rapidly
+appearing around the new business center of the city. The facilities
+afforded by the telephone and the subway for communication with the
+money center have doubtless greatly promoted this up-town movement.</p>
+
+<p>When the Pennsylvania Tunnel Extension is in operation, the
+easiest and quickest way for the passenger to reach the city from
+Newark will bring him into the Pennsylvania Station at Seventh
+Avenue and 33d Street. The schedule fast time from Newark to the
+New York Cortlandt Street Station is now 25 min. This may be
+reduced to about 18 min. by the use of the Hudson Company's tunnels,
+and while this involves inconvenience in changing transportation at
+Jersey City, yet it brings the traveler three blocks nearer Broadway.
+The time from Newark to the Pennsylvania Station will be about
+17 min., and the trip will be made without change of transportation,
+so that, undoubtedly, by far the greater part of the Pennsylvania's
+passenger traffic desiring to reach the shopping and hotel center of the
+city will go to the new up-town station.<span class='pagenum'><a name="Page_31" id="Page_31">[31]</a></span></p>
+
+<p>The effect of the Tunnel Extension in increasing the volume and
+rapidity of the up-town movement and the real estate values will be
+very great; indeed, its influence is already apparent, although the line
+is not yet opened for traffic. With the extension of the present subway
+down town on the west side with direct connections to Brooklyn, and
+up town from 42d Street to the Bronx, with connections to permit
+convenient transfers between these two straightaway subways&mdash;one on
+the east side and the other on the west side of Manhattan&mdash;the Pennsylvania
+Station will become a great center for receiving and distributing
+passenger traffic between all the Boroughs of the City and outlying
+points. The new post office to be established adjacent to the Terminal
+Station will also greatly assist in accelerating the up-town movement.</p>
+
+<p>In concluding this account of the New York Tunnel Extension
+project, the writer desires to pay a tribute of admiration and respect
+to the memory of the late A.&nbsp;J. Cassatt, President of the Pennsylvania
+Railroad Company, to whom the conception, design, and execution
+of the project are mainly due. His education and experience as
+a civil engineer, his thorough knowledge of all the details of railroad
+construction, operation, and management, gained by long and varied
+service, the directness, clearness, and strength of his mind, and his
+great executive ability, placed him at the head of the railroad men of
+the country. In the consideration of great problems, whether of transportation,
+finance, commerce, or political economy, he was almost unequaled,
+owing to the breadth, originality, and decisiveness of his
+character; yet his manner to his subordinates was so direct and simple
+that he seemed unconscious of his own superiority. Great as it is,
+the New York plan of improvement is only one item in a far-reaching
+scheme of development which became the policy of the Pennsylvania
+Railroad Company through Mr. Cassatt's advice and influence, yet his
+strongest interest was doubtless centered in the New York works. It
+is the sincere regret of all connected with the design and execution
+of the project that he did not live to see its completion.</p>

+THE NEW YORK TUNNEL EXTENSION OF THE PENNSYLVANIA RAILROAD.
+
+BY CHARLES W. RAYMOND, M. AM. SOC. C. E.[A]
+
+
+
+
+Some time before the appointment of the Board of Engineers which
+supervised the designing and construction of the New York Tunnel
+Extension of the Pennsylvania Railroad, the late A. J. Cassatt, then
+President of the Company, said to the writer that for many years he had
+been unable to reconcile himself to the idea that a railroad system like
+the Pennsylvania should be prevented from entering the most important
+and populous city in the country by a river less than one mile wide. The
+result of this thought was the tunnel extension project now nearly
+completed; but it is only in recent years that new conditions have
+rendered such a solution of the problem practicable as well as
+desirable.
+
+Previously a tunnel designed for steam railroad traffic, to enter New
+York City near Christopher Street, was partly constructed, but the work
+was abandoned for financial reasons. Then plans for a great suspension
+bridge, to enable all the railroads reaching the west shore of the North
+River to enter the city at the foot of 23d Street, were carefully
+worked out by the North River Bridge Company. The Pennsylvania Railroad
+Company gave this project its support by agreeing to pay its _pro rata_
+share for the use of the bridge; but the other railroads declined to
+participate, and the execution of this plan was not undertaken.
+
+New operating conditions, resulting from the application of electric
+traction to the movement of heavy railroad trains, which had been used
+initially in tunnels by the Baltimore and Ohio Railroad and was
+subsequently studied and adopted by railroads in Europe, made it
+possible to avoid the difficulty of ventilation connected with steam
+traction in tunnels, and permitted the use of grades practically
+prohibitive with the steam locomotive. The practicability of the tunnel
+extension project finally adopted was thus assured.
+
+The acquisition of the control of the Long Island Railroad by the
+Pennsylvania Railroad Company, which occurred in 1900, introduced new
+and important elements into the transportation problem, from a freight
+as well as a passenger standpoint. Previously, the plans considered had
+for their only object the establishment of a convenient terminus in New
+York, to avoid the delays and difficulties involved in the necessity of
+transporting passengers and freight across the North River. When the
+Long Island Railroad became practically a part of the Pennsylvania
+System, it was possible and desirable to extend the project so as to
+provide, not only for a great prospective local traffic from all parts
+of Long Island, but also for through passenger and freight traffic to
+the New England States, and to and from all points on the Pennsylvania
+System, thus avoiding the long ferriage from Jersey City around the
+harbor to the Harlem River.
+
+This paper has for its subject the New York Tunnel Extension project,
+and is intended merely as an introduction to the detailed accounts of
+the construction of the various divisions of the line to be given in
+succeeding papers prepared by the engineers who actively carried out the
+work. The project, however, forms the most important part of the
+comprehensive scheme adopted by the Pennsylvania Railroad Company for
+conducting its traffic into and through New York City, and a brief
+description of this general plan is therefore necessary in order that
+the relations of the tunnel line to the other parts of the
+transportation project may be clearly understood.
+
+
+GENERAL PLAN FOR TRAFFIC FACILITIES AT NEW YORK.
+
+The component elements of the general plan outlined by the late A. J.
+Cassatt, President, in his open letter to the Board of Rapid Transit
+Railroad Commissioners of the City of New York, dated January 18th,
+1906, are indicated on Fig. 1, and may be briefly summarized as follows:
+
+_1._--The Pennsylvania Tunnel and Terminal Railroad, generally referred
+to as the New York Tunnel Extension of the Pennsylvania Railroad. This
+line begins near Newark, N. J., crosses the Hackensack Meadows, and
+passes through Bergen Hill and under the North River, the Borough of
+Manhattan, and the East River to the large terminal yard, known as
+Sunnyside Yard, in Long Island City, Borough of Queens, New York. The
+line will be more fully described elsewhere.
+
+_2._--The electrification of the Long Island Railroad within the city
+limits.
+
+_3._--The Pennsylvania freight terminal yard and piers at Greenville,
+N. J., connecting by ferry with the Bay Ridge terminal of the Long
+Island Railroad.
+
+_4._--The Bay Ridge Improvement of the Long Island Railroad from East
+New York to Bay Ridge.
+
+_5._--Yards for increasing the freight facilities in the Boroughs of
+Brooklyn and Queens.
+
+_6._--The Atlantic Avenue Improvement in Brooklyn, involving the removal
+of the steam railroad surface tracks and the extensive improvement of
+the passenger and freight station at Flatbush Avenue.
+
+_7._--The New York Connecting Railroad, extending through a part of the
+Borough of Queens and crossing the East River by a bridge at Ward's and
+Randall's Islands to Port Morris, N. Y.
+
+_8._--The Glendale Cut-Off of the Long Island Railroad.
+
+_9._--New piers and docks in Newtown Creek at its confluence with the
+East River.
+
+_10._--Electrification of the United Railroads of New Jersey Division
+from Newark to Jersey City.
+
+The parts sustained by these elements in the work of transportation and
+distribution are briefly as follows:
+
+The New York Tunnel Extension is essentially a passenger line, although
+the Company has not only the legal powers but also the facilities for
+making it a through route for freight if desired. It will transport
+passengers to and from the centrally located station at 33d Street and
+Seventh Avenue in New York City, joining the Long Island System at
+Sunnyside Yard, and, by means of the New York Connecting Railroad, it
+will form a link in the through traffic line, connecting the whole
+Pennsylvania System with the New England States. This line has been
+designed for the safe and expeditious handling of a large volume of
+traffic. The requirements include handling the heaviest through express
+trains south and west from the main line as well as the frequent and
+lighter local-service trains. For through service the locomotive
+principle of operation has been adhered to, that is, electric
+locomotives will take up the work of the steam locomotives at the
+interchange yard at Harrison, N. J., and, for excursion and suburban
+service to nearby towns, provision will be made for electric
+locomotives, or by operation of special self-propelled motor cars in
+trains, the project being planned to give the greatest flexibility in
+method of operation to meet the growing demand in the best way.
+
+The New York Connecting Railroad has important functions both for
+freight and passenger service. When constructed it will be about 12
+miles long, and will form a part of the line to the New England States
+for through passenger and freight service, and also carry local freight
+to and from Sunnyside Yard and Brooklyn, and all points on Long Island.
+By means of this line it will be possible to make the Brooklyn station
+at Flatbush Avenue a station on the through System for New England as
+well as the Western States.

+MAP OF THE PENNSYLVANIA R. R. CO'S NEW YORK TUNNEL EXTENSION AND
+CONNECTIONS.]
+
+The initial equipment of the Western Division of the Long Island
+Railroad for electric traction has been made in advance of the opening
+of the tunnel line in order to take care of the requirements of the
+Atlantic Avenue improvement. This improvement involved the elimination
+of grade crossings within the City of Brooklyn and the conversion of the
+railroad line which was previously on the surface of the streets to part
+subway and part elevated line from the Flatbush Avenue Terminal to East
+New York Station, a distance of 5-1/4 miles. One of the requirements of
+this improvement was that the motive power should be changed to some
+form of power not involving combustion. This led to the adoption of
+electricity, and, in order to meet operating necessities, involved the
+electrification of connecting lines beyond the improvement proper, so
+that local service could be handled to the end of the runs without
+changing the motive power. The extent of the electrification thus
+required was found to be about 100 single-track miles. This extensive
+electrification work was undertaken and completed in the summer of 1905,
+upon the completion of the Atlantic Avenue improvement proper, and since
+that time has been in successful operation. On the near approach of the
+construction of the New York Terminal improvement, plans for additional
+electrification on the Long Island Railroad were made, and the work is
+now in progress on the extensive additions required to couple up the
+tunnel extension with the various lines centering at the Long Island
+City terminus.
+
+The Bay Ridge Improvement of the Long Island Railroad comprises the
+readjustment of the right of way and the establishment of new grades in
+order to do away with grade crossings from the freight terminal at Bay
+Ridge to a junction with the New York Connecting Railroad at East New
+York, a distance of 10.4 miles. It also provides for the re-location of
+the line and the elimination of grade crossings on the branch running to
+Manhattan Beach, a distance of 3.7 miles. The work is being executed
+without interrupting traffic, and in all about 75 grade crossings will
+be abolished. This improvement became necessary in order to provide for
+the rapid extension of population into the suburban districts and for
+the present and future requirements of the section, to establish
+municipal conveniences and facilities, and to open additional streets
+across the right of way. To accomplish these ends, the line has been
+built in cuts and on embankments, there being about 6.4 miles of the
+former, 3.3 miles of the latter, and a tunnel, 3,500 ft. long, where the
+line crosses the Atlantic Avenue improvement.
+
+The Atlantic Avenue improvement, as mentioned above, involved the
+removal of the railroad tracks from the street surface for a distance of
+about 5-1/4 miles. This was done by constructing a series of elevated
+and subway structures, there being about 2.1 miles of the former, 2.4
+miles of the latter, and 0.8 mile of approaches, eliminating more than
+90 grade crossings. In the light of recent developments, it may be of
+interest to note that one of the reasons for establishing a combination
+elevated and subway line was that, at the time the improvement was
+projected, no underground railroad in the country, of similar length and
+carrying a heavy volume of local traffic, was operated by electricity,
+and public sentiment was against the operation of the entire length of
+the line underground by steam power. This improvement also provided for
+depressing the entire Flatbush Avenue station and a freight yard. As the
+work progressed, the original plans for the station were greatly
+enlarged, the remodeled station covering about 61 city lots.
+
+The main point of passenger distribution is the New York station. Other
+important stations will be Flatbush Avenue, Brooklyn; Jamaica, Long
+Island, where the changes to and from electric motive power will be
+made; and Newark, N. J. Many other places, including the seaside resorts
+on Long Island and in New Jersey, will feel the benefits of the direct
+tunnel railroad into and through New York City. The Glendale Cut-Off
+will materially shorten the route and running time from New York through
+the tunnels to Rockaway Beach.
+
+The plans contemplate that passengers to and from the lower part of
+Manhattan will be carried by the steam line between Newark and Jersey
+City and cross the North River by ferry or the Cortlandt Street tunnels
+of the Hudson Company. Eventually, the old main line will be electrified
+and supersede the steam service between Newark and Jersey City.
+
+The Greenville Yard is the most important point for the receipt,
+transmission, and distribution of freight. From this point freight can
+be transported, without breaking bulk, by a comparatively short
+car-ferry to the Long Island Railroad terminus at Bay Ridge, and thus a
+very large part of the Pennsylvania Railroad Company's floatage in New
+York Harbor and the East River will be abolished, the floatage distance
+being reduced in the case of the New England freight from about 12 to 3
+miles. This traffic will be routed from Bay Ridge _via_ the Long Island
+Railroad to a connection with and thence over the New York Connecting
+Railroad to the New York, New Haven and Hartford Railroad at Port
+Morris, N. Y.
+
+As the facilities for the handling of freight in the Boroughs of
+Brooklyn and Queens had become insufficient for taking care of the
+prospective traffic, eleven new local delivery yards, having a combined
+area of about 2,153 city lots, have been established, and three existing
+yards are to be improved and enlarged so as to give a combined area of
+about 687 city lots. Of these new yards, the Bay Ridge freight terminal,
+containing about 790 city lots, is the largest; its functions have been
+described above. There is a freight terminal at East New York 200 ft.
+wide and a mile long, containing about 566 city lots, which will be the
+distributing point of freight for the entire East New York section. This
+yard is depressed, and will be crossed by six viaducts carrying city
+streets. The North Shore freight yard, containing 109 city lots, is
+connected with the Montauk Division by an overhead construction, known
+as the Montauk Freight Cut-Off, whereby all freight traffic to Jamaica
+may be kept out of the way of the Jamaica passenger traffic from the
+tunnels.
+
+It may be of interest to indicate briefly how much has already been
+accomplished in the execution of this general plan, and what still
+remains to be done for its completion.
+
+The larger part of the electrification of the Long Island Railroad and
+the elimination of grade crossings within the built-up city limits, the
+Atlantic Avenue improvement, and the yard and piers at Greenville, have
+been completed. The Sunnyside Yard and the Glendale Cut-Off will be
+completed during the next twelve months. On the Tunnel and Terminal
+Railroad the embankment and bridge work across the Hackensack Meadows
+and all the tunnels and excavation from the west side of Bergen Hill to
+Long Island City, except a short section near the eastern end of the
+line, have been completed. The New York station and other buildings and
+facilities connected therewith are well advanced. The laying of the
+track, the electrification of the line, and the installation of the
+signaling and lighting systems are under way. It is anticipated that the
+line will be ready for operation in the spring of 1910.
+
+Report has been made to the Public Service Commission that a large part
+of the right of way for the New York Connecting Railroad has been
+obtained, and more than $3,000,000 has been spent by this railroad. The
+piers and docks at Newtown Creek and the electrification of the line
+from Newark to Jersey City are not yet actively under way.
+
+
+ESTIMATED COST OF THE IMPROVEMENTS.
+
+As appears from the foregoing statement, only parts of the improvements
+contemplated in the general scheme have been completed, others are in
+progress, and others have not yet been commenced. It is therefore
+impossible at the present time to make a close estimate of the total
+expenditure involved in the execution of the entire scheme. The
+following estimate of the cost of the Pennsylvania Railroad Company's
+improvements in the New York District when fully completed is based on
+the best information now available:
+
+New York Tunnel Extension and Station, including
+Interchange Yards at Harrison,
+N. J., and Sunnyside, L. I., P. T. & T.
+R. R. Co. $100,000,000
+
+Long Island Railroad electrification, Bay
+Ridge and Atlantic Avenue improvements,
+Glendale Cut-Off, freight yards,
+and new equipment 35,000,000
+
+New York Connecting Railroad, to be built
+jointly by the Pennsylvania R. R. Co.
+and the New York, New Haven and
+Hartford R. R. Co., about 14,000,000
+
+Pennsylvania Railroad improvements in the
+State of New Jersey, electrification of
+line from Jersey City to Park Place,
+Newark, Greenville freight line and terminal
+on New York Bay 10,000,000
+ ------------
+ Total $159,000,000
+
+
+CORPORATE ORGANIZATION AND FRANCHISE CONDITIONS.
+
+As the tunnel extension lies partly in the State of New Jersey and
+partly in the State of New York, it was necessary to charter two
+companies, each covering the territory within the State to which it
+belonged. The New Jersey corporation was entitled the Pennsylvania, New
+Jersey and New York Railroad Company, and the New York corporation, the
+Pennsylvania, New York and Long Island Railroad Company. These
+organizations were completed early in 1902. Subsequently, after the
+tunnels had been joined under the North River, the companies were
+consolidated, on June 26th, 1907, and thereby formed the present company
+under the name of the Pennsylvania Tunnel and Terminal Railroad Company,
+a corporation of both States.
+
+Mr. Cassatt, President of the Pennsylvania, New York and Long Island
+Railroad Company, made application in its behalf for a franchise to
+extend the lines of the Pennsylvania Railroad by tunnels under the North
+River to a passenger station to be erected in New York City and thence
+under the East River to a connection with the Long Island Railroad, on
+May 5th, 1902.
+
+The franchise for that part of the tunnel line which is within the State
+of New York, that is, from the boundary line between New York and New
+Jersey, in the Hudson River, to the eastern terminus at Sunnyside Yard,
+Long Island, is contained in the certificate issued by the Board of
+Rapid Transit Railroad Commissioners of the City of New York on October
+9th, 1902.
+
+The essential features of the franchise have been summarized
+substantially as follows in the report of the Committee of the Board of
+Rapid Transit Railroad Commissioners of the City of New York, dated June
+14th, 1902:
+
+_First._--A grant by the city in perpetuity of rights, subject, however,
+to a periodic readjustment of payments at intervals of twenty-five
+years, as follows:
+
+ (_a_) To construct and operate a railroad of two tracks from the
+ boundary between New York and New Jersey under the Hudson River
+ opposite the westerly foot of Thirty-first Street, Borough of
+ Manhattan, thence running under the Hudson River and Thirty-first
+ Street to the East River and under the East River to a terminus in
+ Queens Borough. The Company is permitted on notice within ten years
+ to give up the right to these two tracks.
+
+ (_b_) A like right for a railroad of two tracks beginning near the
+ same point under the Hudson River, thence running under
+ Thirty-second Street to the East River, and under that river to the
+ terminus in Queens Borough, with a right for two additional tracks
+ in Thirty-second Street, west of Ninth Avenue, and one additional
+ track between Seventh and Fifth Avenues in Manhattan.
+
+ (_c_) A like right for a railroad of two tracks beginning at the
+ station terminal site at Thirty-third Street and Seventh Avenue and
+ thence running under Thirty-third Street and the East River to the
+ terminal in Queens Borough, with a right for one additional track
+ on Thirty-third Street, between Seventh and Fifth Avenues.
+
+ (_d_) A right to maintain a terminal station occupying the four
+ blocks bounded by Thirty-first Street, Seventh Avenue, Thirty-third
+ Street and Ninth Avenue, the lots on the east side of Seventh
+ Avenue between Thirty-first and Thirty-third Streets, and the
+ underground portions of Thirty-first and Thirty-third Streets,
+ between Seventh and Eighth Avenues and between Eighth and Ninth
+ Avenues, the Company having itself acquired the land included in
+ such four blocks and lots on the east side of Seventh Avenue.
+
+ (_e_) To occupy for such terminal facilities all of Thirty-second
+ Street lying between the westerly side of Seventh Avenue and the
+ easterly side of Eighth Avenue, and between the westerly side of
+ Eighth Avenue and the easterly side of Ninth Avenue. As soon as the
+ statutory right of the city authorities to make the conveyance
+ shall be put beyond doubt the Railroad Company is obliged to buy
+ such two portions of Thirty-second Street, which will then become
+ completely dedicated to the purposes of their station. (These
+ portions of Thirty-second Street were subsequently purchased by the
+ Railroad Company.)
+
+ (_f_) To have along such routes the necessary facilities for the
+ operation of passenger and freight trains, including telegraph
+ wires and the various wires and cables for the distribution of
+ power, heat, and light.
+
+_Second._--The requirement of the consent of the Mayor, the Board of
+Aldermen, the Board of Estimate and Apportionment, and the other
+authorities of the city having control of the streets.
+
+_Third._--The obligation of the Pennsylvania Company to begin
+construction within three months after obtaining the necessary consents
+and complete the railroad within five years after construction shall
+begin, except the route under Thirty-first Street, for the completion of
+which the company is allowed ten years after the completion of the
+remainder of the railroad.
+
+_Fourth._--Payments by the Pennsylvania Company for the first
+twenty-five years, as follows: A rental of $200 per annum for the right
+to occupy land under the Hudson and East Rivers outside of pier lines. A
+rental for ground within pier lines and for underground portions of
+streets in Manhattan Borough, at fifty cents per linear foot of single
+track per annum, for the first ten years, and during the next fifteen
+years one dollar per annum per linear foot. A rental for ground within
+pier lines and for underground portions of streets in Queens Borough at
+one-half the rates payable for Manhattan Borough. A rental for
+underground portions of Thirty-first and Thirty-third Streets, between
+Seventh and Eighth Avenues, and between Eighth and Ninth Avenues (such
+portions extending almost up to the surface, except under the south
+sidewalk of Thirty-first Street and north sidewalk of Thirty-third
+Street) at $14,000 per annum for the first ten years, and at $28,000 per
+annum for the next fifteen years.
+
+For the portions of Thirty-second Street, between Seventh and Eighth
+Avenues, and between Eighth and Ninth Avenues, when the statutory power
+of the city to make a sale shall be put beyond doubt, the city is to
+sell and the Railroad Company is required to buy such portions for the
+sum of $788,600. The rentals for river and track rights begin at the
+date of operation. For the underground spaces under Thirty-first and
+Thirty-third Streets, used for station extension, the rentals begin at
+the commencement of construction, or when the company entered thereon.
+
+Such annual payments may be summarized as follows:
+
++===============================================+=========================+
+| | First 10 | Next 15 |
+| | years. | years. |
+|-----------------------------------------------+------------+------------+
+|For river rights | $200.00 | $200.00 |
+|For tunnel rights in Manhattan Borough, being | | |
+| 44,341 ft. (partly estimated) of single track | 22,170.00 | 44,341.00 |
+|For tunnel rights in Queens Borough, being | | |
+| 8,100 ft. (partly estimated) of single track | 2,025.00 | 4,050.00 |
+|For street rights on Thirty-first and | | |
+| Thirty-third Streets, north and south of | | |
+| terminal | 14,000.00 | 28,000.00 |
++-----------------------------------------------+------------+------------+
+| In all, per annum | $38,395.00 | $76,591.00 |
++===============================================+============+============+
+
+If the route under Thirty-first Street be availed of, these amounts will
+be increased by $16,652.50 for the first ten years, and by $33,305 for
+the next fifteen years.
+
+The amounts to be paid are to be readjusted at the end of twenty-five
+years; and thereafter at intervals of twenty-five years. If the city and
+the Railroad Company shall not agree upon the readjusted rates, they are
+to be determined by the Supreme Court of this State.
+
+_Fifth._--The railroad to be entirely in tunnel except where it
+approaches the surface at its eastern terminal near Thomson Avenue, in
+Queens Borough. The uppermost part of the tunnel is to be at least
+nineteen feet below the surface of the street; but this limitation does
+not apply to the portions of Thirty-first and Thirty-third Streets
+opposite the terminal station between Seventh and Ninth Avenues, where
+the Company may occupy the underground portions of the street under the
+roadway to within thirty inches of the surface, and under the sidewalks
+on Thirty-first and Thirty-third Streets opposite to the station to
+within five feet of the surface, the company to properly care for
+sewers, water, gas and other pipes and underground structures lawfully
+in the street.
+
+_Sixth._--The company to make good all damage done to property of the
+city by its construction work or operations, and to abutting owners all
+damage done through any fault or negligence of the company, or of any
+contractor or sub-contractor engaged upon its work of construction or
+operation. The Tunnel Company to keep Thirty-first and Thirty-third
+Streets opposite the station well paved with smooth pavement and in
+thoroughly good condition.
+
+_Seventh._--Tunnel excavations to be done without disturbing the surface
+of the street, except in the portions of Thirty-first and Thirty-third
+Streets, and Seventh, Eighth and Ninth Avenues in front of the terminal
+station, and except in Queens Borough, with the power to the Rapid
+Transit Board, wherever conditions elsewhere make surface excavation
+necessary for efficient construction, to grant the right for such
+excavation, subject to conditions to be then prescribed by the Board.
+The tracks are to be constructed of the most approved plan so as to
+avoid noise or tremor. All plans for, and the method of doing, the work
+are made subject to the approval of the Rapid Transit Board.
+
+_Eighth._--The motive power to be electricity, or such other power not
+involving combustion as may be approved by the Board.
+
+_Ninth._--The company to have no power to carry on merely local traffic,
+except with the approval of the Board and for additional consideration
+to be paid the city. Traffic is defined as local which begins and ends
+in the city within five miles of the terminal station on Seventh and
+Ninth Avenues.
+
+_Tenth._--The railroad to be diligently and skillfully operated, with
+due regard to the convenience of the traveling public.
+
+_Eleventh._--The city to have a lien upon the franchise and real
+property of the company to secure the payment of rental.
+
+_Twelfth._--The rights of the city to be enforceable by action, for
+specific performance, or mandamus, or otherwise.
+
+_Thirteenth._--The company not to oppose the construction of any rapid
+transit railroad along or across the same routes which do not actually
+interfere with the authorized structures of the company.
+
+_Fourteenth._--The city to have an ample right of inspection of the
+railroad, and to enter upon it for examination, supervision, or care of
+city property, or for other purposes.
+
+_Fifteenth._--The company to be bound to maintain and strengthen all
+parts of its railways under streets or avenues so that the same shall
+support safely any structures superimposed or which may hereafter be
+superimposed thereon by the city or under public authority.
+
+_Sixteenth._--The company to have the right to convey or mortgage the
+franchise, but every grantee, whether directly or under a mortgage, to
+assume the obligations already assumed by the Railroad Company and the
+Railroad Company not to be relieved of such obligations by the grant.
+
+This franchise was passed by the Board of Aldermen on December 16th and
+approved by the Mayor on December 23d, 1902.
+
+Subsequently, an agreement, dated June 21st, 1907, was entered into by
+the City of New York, the Tunnel Company, and the Long Island Railroad
+Company covering the construction of the Sunnyside Yard, which forms the
+eastern terminus of the line.
+
+In pursuance of this agreement, the map or plan of the City of New York
+was changed by discontinuing or closing portions of fifty streets or
+avenues, and by changing the grades of sixteen streets or avenues, in
+the Borough of Queens, and the portions of streets and avenues thus
+discontinued and closed, most of which were not opened for public use,
+were sold to the Railroad Companies. The agreement, however, reserved to
+the City permanent and perpetual underground rights and easements to
+maintain in a reasonable manner, not inconsistent with the construction
+and operation of the railroad facilities of the Companies, its existing
+sewers, drains, and other sub-surface structures in, under, and through
+the lands within the lines of the discontinued portions of each of such
+streets and avenues, including the right to repair, rebuild, and enlarge
+the same, and to construct in a reasonable manner, not inconsistent with
+the construction and operation of the railroad facilities of the
+Companies, such additional sewers or drains in, under, or through the
+lands as may be hereafter required by the City, together with the right
+to enter upon the premises from time to time as may be necessary for the
+purpose of inspecting, repairing, constructing, or rebuilding the
+sub-surface structures.
+
+The agreement required the Companies to construct at their expense, four
+viaducts or bridges over their tracks and terminal development, three
+with roadways 42 ft. wide, one with a roadway 60 ft. wide, and each to
+have two sidewalks 10 ft. wide, the work to include the paving of the
+roadways and sidewalks.
+
+The Companies are further required to pay one-half the cost of the
+construction of the foundations, abutments, piers, superstructures, and
+approach of an additional viaduct or bridge over the Sunnyside Yard, to
+have a roadway not more than 60 ft. wide and two sidewalks each 10 ft.
+wide, and to grant the City of New York a perpetual easement for the
+continuance of the same in the location upon which it shall be
+constructed.
+
+The agreement further provides that the Companies shall not injure the
+sewers or other substructures now existing or hereafter constructed
+under the streets and avenues, and, in case of injury, that they shall
+repair them or pay the cost thereof; that the viaducts shall be
+completed within the shortest time consistent with their safe and proper
+construction, and that during their construction temporary streets shall
+be provided for the accommodation of traffic.
+
+The Companies are required to bear all the expense of changes of grade
+in the streets and avenues, except those made necessary by the
+construction of the viaduct or bridge to be paid for in part by the
+City; to indemnify the City against all liability for any and all
+damages which may accrue on account of any street which may be closed or
+the grades of which may be changed in pursuance of the agreement; to
+assume all liabilities by reason of the construction or operation of the
+railroads, or the construction of the viaducts, and to save the city
+harmless from any liability whatever, to either persons or property, by
+reason of the construction or operation of the railroads or the
+construction of the viaducts.
+
+The Companies are also required to indemnify the City against and pay
+the cost of all alterations which may be required to the sewerage or
+drainage system or to any sub-surface structures and pipes laid in the
+streets or avenues on account of the construction and operation of the
+terminal, passenger yard, or freight yard of the Companies, or on
+account of the changes in grades or street system.
+
+The Companies are authorized, if they deem it necessary to the
+construction or to the efficient operation of the terminal passenger
+yard or freight yard, to depress, at their expense, any pipes or other
+sub-surface structures now under the surface of any of the portions of
+the streets or avenues discontinued or closed, or to elevate and carry
+the same upon any of the viaducts or bridges, the plans of such
+depression or elevation to be approved by the Board of Estimate and
+Apportionment.
+
+All works within, upon, or over the public streets and avenues are
+subject to the supervision and inspection of the proper municipal
+officer or officers, under such regulations as he or they may determine
+and be authorized by law to impose; and the plans for the construction
+of viaducts or bridges are to be approved by the Board of Estimate and
+Apportionment.
+
+The Companies are required to cede to the City of New York perpetual
+easements for the right to continue and maintain the viaducts or bridges
+over the streets and avenues, sufficient for their control by the City
+for the purpose of police regulation and other control contemplated by
+the City ordinances for the case of streets or highways; reserving,
+however, the right to construct and maintain, at their own expense, such
+connections between the viaducts or bridges and their property as shall
+not interfere with the use of the viaducts or bridges for street
+purposes.
+
+The Companies are also required to cede to the City, grade and curb,
+portions of five existing or proposed streets or avenues, and to pave
+portions of two other avenues.
+
+Mr. A. J. Cassatt, President of the Pennsylvania Railroad Company, was
+President of the Companies constituting the New York Tunnel Extension
+until his death on December 28th, 1906, and Mr. James McCrea, President
+of the Pennsylvania Railroad Company, was elected his successor, and is
+now President of the Pennsylvania Tunnel and Terminal Railroad Company.
+
+Mr. Samuel Rea, Second Vice-President of the Pennsylvania Railroad
+Company, has served as Vice-President since the incorporation of the
+enterprise.
+
+Mr. A. J. County has been Assistant to the President since June 26th,
+1907, and prior thereto and from the incorporation of the tunnel
+enterprise served as Secretary of the Pennsylvania, New Jersey and New
+York Railroad Company and as Assistant Secretary of the Pennsylvania,
+New York and Long Island Railroad Company, which, as heretofore stated,
+constitute the Pennsylvania Tunnel and Terminal Railroad Company.
+
+
+ENGINEERING ORGANIZATION.
+
+Mr. Rea, Vice-President, has general charge of all matters involved in
+the designing and execution of the project.
+
+_The Board of Engineers._--Before the beginning of the work, the
+Management appointed a Board of Engineers which was instructed to
+examine into the New York Tunnel Extension project; to pass upon the
+practicability of the undertaking; to determine upon the best plans for
+carrying it out; to make a careful estimate of its cost; and, if the
+work was undertaken, to exercise general supervision over its
+construction.
+
+President Cassatt's letter appointing the Board contains the following
+further instructions:
+
+"You are requested to procure all additional information that may be
+needed, sparing neither time nor any necessary expense in doing so, for
+I am sure it is not necessary for me to say that, in view of the
+magnitude and great cost of the proposed construction, and of the novel
+engineering questions involved, your studies should be thorough and
+exhaustive, and should be based upon absolute knowledge of the
+conditions."
+
+The Board was organized on January 11th, 1902, when it held its first
+session, and continued in the performance of its duties until April
+30th, 1909, when it was dissolved, its work having been completed.
+
+The Board held regular and special sessions to receive progress reports
+from the Chief Engineers in direct charge of construction, and to
+consider questions relating to the plans and details of the work
+submitted by its members or referred to it by the Management. It then
+reported its conclusions to the Vice-President for approval before the
+work was undertaken.
+
+The Management earnestly impressed upon the Board throughout the whole
+period of its labors, that the Tunnel Extension and facilities were to
+be designed and constructed without regarding cost as a governing
+factor, the main considerations being safety, durability, and proper
+accommodation of the traffic. No expenditure tending to insure these
+conditions was to be avoided.
+
+The Board, when organized, was composed as follows: Col. Charles W.
+Raymond, Corps of Engineers, U. S. Army, Chairman; Messrs. Gustav
+Lindenthal, Charles M. Jacobs, Alfred Noble, and William H. Brown.
+
+Mr. George Gibbs was appointed a member of the Board on April 9th, 1902.
+Mr. Lindenthal resigned on December 15th, 1903, and Mr. Brown resigned
+on March 1st, 1906. Mr. Rea and all the members of the Board are members
+of the American Society of Civil Engineers, and Mr. Noble is a
+Past-President of the Society.
+
+Mr. William R. Mead, of the firm of McKim, Mead, and White, Architects
+for the Terminal Station, was associated with the Board for the
+consideration of architectural subjects.
+
+Mr. Robert H. Groff, Secretary of the Company, was also Secretary of the
+Board until his resignation on January 31st, 1907. Mr. William Couper
+was Acting-Secretary from April 15th, 1907, to April 30th, 1909.
+
+S. Johannesson, Assoc. M. Am. Soc. C. E., was Engineer Assistant to the
+Chairman from December 1st, 1905, to April 30th, 1909.
+
+_Division of the Work._--For the purposes of actual construction, the
+line was divided into four parts: the Meadows Division, the North River
+Division, the Terminal Station, and the East River Division. A chief
+engineer appointed by the Management had charge of the construction of
+each Division. The chief engineers exercised full authority in the
+organization of the working forces, and in the general conduct and
+management of the work of construction on their respective Divisions, in
+accordance with the plans for such work approved by the Board of
+Engineers and the Management.
+
+Architects were employed to design the Terminal Station building and
+superintend its erection; and structural engineers to design and erect
+steel structures and facilities, and carry on the work under the
+direction of a Chief Engineer of the Company.
+
+Committees, consisting principally of officers of the Pennsylvania
+Railroad Company, co-operating with the regular engineering
+organization, were appointed to consider the operating features of the
+project, so that the experience of the Pennsylvania Railroad Company's
+organization might be utilized in the work.

+
+
+DESCRIPTION OF THE LINE.
+
+The following summary description of the various divisions of the line
+is intended to give a comprehensive idea of the general features of the
+project. Full details will be given in succeeding papers. The line and
+its respective divisions are shown on Plate I.
+
+_Meadows Division._--Chief Engineer until March 1st, 1906, Mr. William
+H. Brown, Chief Engineer, Pennsylvania Railroad Company, when he retired
+from active service with the latter Company; since March 1st, 1906, Mr.
+Alexander C. Shand, Chief Engineer, Pennsylvania Railroad Company.
+
+This Division consists of an "interchange yard" at Harrison, near
+Newark, N. J., adjoining the tracks of the present New York Division of
+the Pennsylvania Railroad, and a double-track railroad across the
+Hackensack Meadows to the west side of Bergen Hill, a distance of 6.04
+miles. The construction is embankment and bridge work, including bridges
+across the Pennsylvania, Erie, and Lackawanna Railroads, and the
+Hackensack River.
+
+_North River Division._--Chief Engineer, Mr. Charles M. Jacobs.
+
+This Division commences at the west side of Bergen Hill and passes
+through the hill in two single-track rock tunnels to a large permanent
+shaft at Weehawken, near the west shore of the North River, and thence
+eastward a distance of 224 ft. to the Weehawken shield-chamber. It then
+passes under the river through two cast-iron, concrete-lined,
+single-track tunnels, with outside diameters of 23 ft., to a point under
+32d Street, near Eleventh Avenue, in New York City, and thence through
+two single-track tunnels of varying cross-section, partly constructed in
+cut-and-cover, to the east side of Tenth Avenue. It then passes into the
+Station Yard and terminates at the east building line of Ninth Avenue.
+The work included the Station Yard excavation and walls from Tenth
+Avenue to Ninth Avenue, and the retaining walls and temporary
+underpinning of Ninth Avenue. The aggregate length of the line in this
+Division is 2.76 miles.
+
+_New York Station and Approaches._--Mr. George Gibbs, Chief Engineer of
+Electric Traction and Station Construction.
+
+The Station and its approaches extend from the east line of Tenth Avenue
+eastward to points in 32d Street and 33d Street, respectively, 292 ft.
+and 502 ft. east of the west line of Seventh Avenue. This Division
+included the construction of subways and bridges for the support of 31st
+and 33d Streets and Seventh, Eighth, and Ninth Avenues, the Station
+building between Seventh and Eighth Avenues, the foundations for the
+post office to be erected west of Eighth Avenue, the service power-house
+in 31st Street between Seventh and Eighth Avenues, the power-house in
+Long Island City, the traction system, tracks, signals, and
+miscellaneous facilities required in the physical construction of the
+entire terminal railroad ready for operation. Messrs. McKim, Mead, and
+White were the architects for the Station and Messrs. Westinghouse,
+Church, Kerr and Company executed the structural engineering work, both
+in the station and for the support of the streets, as well as the
+construction of the subways.
+
+The station is of steel skeleton construction with masonry curtain
+walls, all supported by a system of columns extending to a rock
+foundation. This building covers two city blocks and one intersecting
+street, and has an area of about 8 acres. It is 774 ft. long, 433 ft.
+wide, with an average height above the street of 69 ft., and a maximum
+of 153 ft. The main waiting-room is 277 ft. long, 103 ft. wide and 150
+ft. high. The Concourse is 340 ft. long and 210 ft. wide.
+
+The level of the track system below the street surface varies from 39 to
+58 ft., and is from 7 to 10 ft. below mean high water in the harbor,
+thereby necessitating the establishment of an elaborate system of
+drainage over the entire station yard area. Access to the street is
+gained by elevators and stairways.
+
+To accelerate the loading and unloading of the trains, high platforms
+will be constructed in the station on a level with the floors of the
+cars, in order to avoid the use of car steps and increase the traffic
+capacity of the station.
+
+There will be 21 standing-tracks at the station, and 11 passenger
+platforms, providing 21,500 ft. of platform adjacent to passenger
+trains. Within the station area, which from Tenth Avenue to the normal
+tunnel sections east of Seventh Avenue comprises 28 acres, there will be
+a total of about 16 miles of track.
+
+The service plant for the installation of machinery for lighting,
+heating, and ventilating the station, and for operating the interlocking
+system, is located in an independent building south of the station.
+
+The Power-House to supply the electrical energy for the operation of the
+tunnel line and the Long Island Railroad is situated on property in
+Queens Borough adjoining the present Long Island Railroad Station near
+the East River, and was constructed under the Chief Engineer of Electric
+Traction and Station Construction. As at present designed, the
+dimensions of the structure are 200 ft. by 262 ft., outside measurement.
+It can accommodate six generating units of 5,500 kw., the standard
+adopted for future work, and two of 2,500 kw. for lighting the tunnels.
+The ultimate capacity of this station when extended will be about
+105,000 kw.
+
+_East River Division._--Chief Engineer, Mr. Alfred Noble.
+
+This Division begins at the eastern limits of the New York Station at a
+point in 32d Street, 292 ft. east of the west line of Seventh Avenue,
+and at a point in 33d Street, 502 ft. east of the west line of Seventh
+Avenue, and also includes the excavation work and retaining walls for
+the station site and yard, to the track level, westward to Ninth Avenue.
+It extends eastward from the station under 32d and 33d Streets through
+tunnels partly three-track and partly so-called twin tunnels to Second
+Avenue; thence the line curves to the left under private property to
+permanent shafts a few feet east of First Avenue. Four single-track,
+cast-iron, concrete-lined tunnels, with outside diameters of 23 ft.,
+pass under the East River, and, after passing through permanent shafts
+near the bulkhead line, reach the surface in Long Island City from 3,000
+to 4,200 ft. east of the East River. The tunnel portals are in
+Sunnyside Yard, which extends to Woodside, the easterly end of the
+Division, and the Yard grading with its buildings and a number of City
+viaducts crossing it were executed under this Division. The total length
+of the Division is 4.48 miles.
+
+The total length of the entire line is 13.66 miles. There are 6.78 miles
+of single-track tube tunnels, and the average length of the tunnels
+between portals is 5.56 miles.

+
+
+GENERAL CONSIDERATIONS.
+
+Details have been omitted from the foregoing description, as they can be
+treated better and more fully by the constructing engineers in
+succeeding papers. There are, however, some general considerations
+involved in the designing of the work, which may, perhaps, be referred
+to more conveniently in this introductory paper, and these will now
+receive attention.
+
+In all parts of the work problems were encountered requiring for their
+solution large expenditures and much engineering skill; but many of
+these difficulties had been frequently met in previous engineering
+experience, and the methods of overcoming them were well understood.
+Thus, in the Meadows Division, a long and heavy embankment, part of
+which was on submerged meadow land, and many bridge foundations had to
+be constructed; in the Bergen Hill tunnels, very tough trap rock was
+encountered; in the tunnels under the city, the work was much
+complicated and its cost increased greatly by the necessity of caring
+for sewers, water and gas pipes, and the foundations of adjacent
+buildings; and many troublesome problems were met in the construction of
+the tunnels connecting the East River tunnels with the Sunnyside Yard.
+
+The novel features of the project, however, were the great tunnels
+extending the line under the North and East Rivers. Tunnels of the kind
+contemplated, to be used for heavy and rapid railroad traffic, had never
+been constructed through materials similar to those forming the beds of
+the North and East Rivers. Questions arising in connection with the
+design and method of construction of the tunnels will be considered
+later. Here they are referred to only in their relation to the location
+and grades of the line, in which connection the conditions controlling
+their establishment were the most important elements.
+
+_Location and Grades._--It was desirable to make the tunnels between
+the bulkhead lines of the rivers as straight as possible, and it was
+necessary to place them at sufficient depth below the dredging plane of
+the War Department (which in the North and East Rivers is 40 and 26 ft.
+below mean low water, respectively) to insure them against possible
+injury from heavy anchors or sunken vessels. Furthermore, they had to
+pass under the piers and bulkheads of Manhattan at a depth sufficient to
+make it certain that they would not affect the stability of those
+structures. Another consideration influencing the establishment of the
+depth of the tunnels below the bottoms of the rivers became important as
+soon as the method of construction by shields with compressed air was
+adopted, namely, the necessity of providing sufficient cover to guard,
+as far as possible, against blow-outs during construction.
+
+The tunnels under the city, connecting the sub-river tunnels with the
+Terminal Station, were located so as to give as favorable grades as
+possible. The provision of the franchise requiring the tops of the
+tunnels to be at least 19 ft. below the Street surface, which had been
+suggested by the Company to permit of future subways, had no effect on
+their location, as other conditions required them to be at a greater
+depth.
+
+The line extending westward from Bergen Hill had to be established so as
+to give ample head-room at the numerous bridges over the railroads and
+highways which it crosses.
+
+Eastward from the East River tunnels, the grades were established so as
+to rise as uniformly as possible to the level of the Sunnyside Yard.
+
+The general features of the line, as finally adopted and constructed,
+are as follows:
+
+The maximum grade west of the Terminal Station occurs on the New York
+side of the North River, and is 2% in the west-bound and 1.93% in the
+east-bound tunnels. The ruling grades (for the ascending traffic) being
+1.32% in the west-bound and 1.93% in the east-bound tunnels. In the
+tunnels east of the Terminal Station the ruling grade is 1.5% for both
+east-bound and west-bound traffic. There is, however, descending with
+the traffic, a short section on a grade of 1.9 per cent. These grades
+would be objectionable with steam locomotives under a heavy traffic, but
+the development of the electric locomotive has rendered possible the
+operation of grades which would have formerly been considered
+prohibitive.
+
+From the junction with the Pennsylvania Railroad, near Harrison, N. J.,
+to Woodside, Long Island, a distance of 13.66 miles, there is an average
+of 1.5 curves per mile; the line having a total curvature of 230
+degrees. The maximum curvature is 2 degrees.
+

+Sunnyside Yard]
+
+_Method of Construction of Sub-River Tunnels._--The character of the
+material through which the tunnels were to be constructed differed
+greatly in the two rivers. The bed of the North River, at the level of
+the tunnels, consists of silt composed principally of clay, sand, and
+water, while that of the East River is formed of a great variety of
+materials, such as quicksand, sand, boulders, gravel, clay, and
+bed-rock. When the method of construction had to be decided there were
+no thoroughly satisfactory precedents to follow in the case of either
+river, although the Gas Tunnel under the East River, the partly
+constructed Hudson Tunnels under the North River, the St. Clair Tunnel
+under the St. Clair River, the Blackwall and several other tunnels under
+the Thames River at London, supplied much useful information. The
+smaller tunnels for a lighter traffic, since so successfully constructed
+under the North and East Rivers, had not then been completed. Under
+these circumstances, it was the desire of the Management that the Board
+should receive and consider proposed methods of construction from all
+available sources; and during the first year of its labors much of its
+time was devoted to the examination and discussion of projects submitted
+for its consideration by engineers and practical builders, some of these
+projects having decided merit. Most of the methods proposed involved
+temporary structures, or the use of floating plant, in the navigable
+channels of the river. This was objectionable in view of the resulting
+obstruction to the enormous river traffic. After full consideration of
+the subject, it was decided to adopt the shield method with compressed
+air for the construction of the tunnels under both rivers, this being
+the only method recommended by the Chief Engineers, and having the great
+advantage of conducting all operations below the bottom of the river,
+thus avoiding obstruction of the channel.
+
+Experience has shown, as was anticipated, that it is much more difficult
+to construct tunnels in such material as occurs in the East River and on
+the New Jersey side of the North River, than in more homogeneous
+material such as is found in the greater part of the North River. During
+the progress of construction under the East River, there were frequent
+blow-outs through fissures opened in the river-bed, and the bottom of
+the river over the tunnel had to be blanketed continuously with clay, to
+check the flow of the escaping air.
+
+In view of the serious difficulties which it was thought might be
+encountered in the application of the shield method to the East River
+work, other methods for the execution of this part of the project
+received special consideration, one of the methods considered being the
+freezing process. It was proposed to drive a small pilot tunnel and
+freeze the ground for a sufficient distance around it by circulating
+brine through a system of pipes established in the tunnel. The pilot
+tunnel was then to be removed and the full-sized tunnel was to be
+excavated in the frozen material and its lining placed in position. By
+this means, it was intended to avoid the danger incident to the use of
+compressed air in material of greatly varying character. This method
+contained too many elements of uncertainty to justify its adoption; but
+as the Management considered it desirable to have, if possible, an
+alternative method, an extended experiment was made with the freezing
+process. A pilot tunnel, 7 ft. 6 in. in diameter, was driven in the bed
+of the East River for a distance of 160 ft., circulating pipes were
+established in it, and brine at a very low temperature was passed
+through the pipes until the ground was frozen for a distance of about
+11.5 ft. around the tunnel. Observations to determine the rate of
+cooling and other important points connected with the process were
+carefully made. When it was found that the construction of the tunnels
+was progressing satisfactorily by the shield method, and that so much
+time was required to freeze the material that the freezing process could
+not be used to advantage in this particular case, the experiment was
+discontinued.
+
+_Design of the Sub-River Tunnels._--The sub-river tunnels consist of a
+circular cast-iron shell, of the segmental, bolted type, having an
+outside diameter of 23 ft., lined with concrete having a normal
+thickness of 2 ft. from the outside of the shell. Through each plate of
+the shell there is a small hole, closed with a screw plug, through which
+grout may be forced into the surrounding material. Each tunnel contains
+a single track. A concrete bench, the upper surface of which is 1 ft.
+below the axis of the tunnel, is placed on each side of the track, the
+distance between benches being 11 ft. 8 in. These benches contain ducts
+for carrying electric cables. The main reason for adopting single-track
+tunnels instead of a larger tunnel containing two tracks was to avoid
+the danger of accidents due to the obstruction of both tracks by
+derailment or otherwise. The tunnels are made just large enough to allow
+the passage of a train with perfect safety, as it was believed that with
+such an arrangement thorough ventilation would be secured by the motion
+of the trains. Experience seems to justify this assumption, but, in
+order to assure thorough ventilation under unusual conditions, such as
+the stoppage of trains in the tunnels, a complete ventilating plant will
+be provided for each tunnel. The rapidity and safety of construction
+were increased by making the tunnel as small as possible, one of the
+difficulties in the shield method of construction being the difference
+in hydrostatic pressure between the top and bottom of the shield, which
+increases with the diameter of the tunnel.
+
+The concrete lining was introduced to insure the permanency of the
+structure, strengthen it from outward pressure and guard it against
+injury from accidents which might occur in the tunnel. The side concrete
+benches were suggested by Mr. Cassatt, President, to confine the trains
+to the center of the tunnels in case of derailment, and to furnish
+sidewalks on each side of the trains so as to obviate the necessity of
+walking on the track.
+
+Refuge niches are constructed in the side benches of the tunnels.
+Manholes, splicing chambers, pump chambers, and other features for the
+handling of the electric cables and drainage, are established at
+intervals.
+
+At points where unusual stresses were anticipated, as for instance where
+the tunnels pass from rock to soft ground, the shell was composed of
+steel instead of cast-iron plates. In the North River tunnels the
+concrete lining in the invert and in the arch was reinforced by
+longitudinal steel bars, but these were not introduced in the East River
+tunnels.
+
+Other details connected with the structures, including the drainage,
+lighting, ventilation, signaling, and electrification systems, will be
+given in succeeding papers.
+
+_Stability of the Sub-River Tunnels._--One of the most important
+questions connected with the design of these tunnels was their probable
+stability under the long-continued action of a heavy and rapid railroad
+traffic. The tunnels are lighter than the materials which they displace
+even when the weight of the heavy live load is included. In the East
+River the character of the material seemed to justify the conclusion
+that the tunnels would not be displaced even under the action of the
+live load. In the North River, however, the tunnels are enveloped by a
+soft silt and it was at first apprehended that some system of supports
+would be advisable to carry the heavy traffic and insure the tunnels
+against displacement under its action. To meet this contingency, which
+was then believed to be a very serious one, it was proposed to sink
+cast-iron screw-piles through the bottom of each tunnel into and through
+the underlying silt until satisfactory bearing material was reached. The
+pile supports were worked out in sufficient detail to be embraced in the
+contract for the construction of these tunnels, with provision, however,
+for omitting them should it be determined subsequently that their use
+was undesirable. The contract plans contained provisions for sliding
+joints where the piles pass through the tunnel floor, so that the live
+load might be carried directly to the pile heads by a system of girders,
+and also for attaching the piles directly to the tunnel, the two plans
+being alternatives.
+
+Investigations, made during the progress of the work to determine the
+physical character of the silt and its action on the tunnels, suggested
+the possibility that the use of pile supports might be inadvisable. This
+view was confirmed by actual experience in the operation of the tunnels
+of the Hudson Companies between Hoboken, N. J., and Morton Street,
+Manhattan, which were opened to traffic in February, 1908. The stability
+of these tunnels under traffic gave further assurance that supports were
+unnecessary under the North River tunnels of the Pennsylvania Railroad
+Company, and they were therefore dispensed with.
+
+_Cross-Passages Between the Tunnels._--The Bergen Hill tunnels, the land
+portions of the North River tunnels and the tunnels under Manhattan are
+connected by cross-passages at intervals varying from 50 to 300 ft. As
+it was the desire of the Management to provide every arrangement
+possible to insure the safety of its passengers and employees and also
+to provide for the convenience of inspection, the question of
+establishing cross-passages between the tunnels under the rivers was
+given most careful consideration. The conclusion was finally reached
+that such passages as it was possible to construct between these tunnels
+might increase instead of diminish the danger in case of accident. No
+more cross-passages have therefore been constructed in the sub-river
+sections, except in the East River, where there is a cross-passage and
+pump chamber combined between each pair of tunnels about 750 ft. from
+the Manhattan bulkhead line.
+
+
+PROBABLE RESULTS OF THE IMPROVEMENTS.
+
+In preceding pages reference has been made to the general objects of the
+improvements included in the project of the Pennsylvania Railroad
+Company for the New York District. While it is impossible, in this
+introductory paper, to analyze fully the transportation problem at New
+York, it seems desirable to indicate briefly some of the more obvious
+effects which the improvements may be expected to produce upon the
+distribution and handling of traffic.
+
+New York City owes its position as the business metropolis of the
+country mainly to its magnificent harbor and the extensive waterfronts
+on its deep, wide rivers, which furnish unrivaled facilities, at a short
+distance from the sea, for foreign and domestic water-borne commerce,
+its foreign commerce being about half the total for the whole country.
+The water-transportation facilities of the port and its tributaries,
+therefore, have always been guarded with jealous care, not only by the
+local commercial interests but also by the General Government.
+
+During recent years, however, the population of the metropolitan
+district has increased so enormously that New York is now the greatest
+terminal passenger and freight traffic center in the country; and in
+manufactures it ranks first among American cities. The new commercial
+interests thus created are of at least equal importance with those of
+the water-borne commerce, although their existence and development are
+largely the result of the water facilities of the port.
+
+The local passenger and freight traffic of the Pennsylvania and of other
+railroads reaching the west shore of the North River is conducted by
+car-floats and ferry-boats which deliver their loads at piers on the
+Manhattan waterfront and elsewhere in the harbor. These boats obstruct
+and endanger the free navigation of the channels and occupy space along
+the waterfront greatly needed for the accommodation of the long-distance
+water-borne commerce, especially on the North River.
+
+In the East River the importance of ferry-boats as a means of traffic
+distribution has already been greatly reduced by the construction of
+bridges and tunnels which provide for the greater part of the passenger
+and vehicular traffic. The North River, however, by reason of its
+greater width and the comparative slowness of its currents, is by far
+the more important waterway for the use of ocean-going vessels of the
+larger classes. In this river the conditions for the construction of
+bridges, within the limits of commercial convenience, seem to be
+practically prohibitory. Tunnels, for the transportation of passengers
+and the diversion of the freight traffic from the inner waters of the
+harbor, are apparently the only available means of relief.
+
+When the new line is in operation, a very large part of the New York
+passenger traffic of the Pennsylvania Railroad will be carried to the
+New York Station at Seventh Avenue and 33d Street and the rest will go
+to Cortlandt Street through the Hudson Company's tunnels. Thus a large
+portion of the Pennsylvania passenger ferry traffic, which amounts to
+more than 91,000 passengers daily, will be practically eliminated from
+the water-transportation problem. In addition, a large part of the Long
+Island Railroad's passengers will use the station at Seventh Avenue and
+33d Street, and its ferry traffic will be reduced accordingly.
+
+The new arrangements for the transfer of freight from Greenville to Bay
+Ridge will relieve the inner waters of the harbor of a large volume of
+obstructive car-float traffic. There appears to be no reason why this
+traffic should not be eventually conducted through tunnels under the
+outer harbor, should future transportation conditions justify the
+enormous cost of such structures.
+
+It is to be remarked that while these new arrangements greatly reduce
+the passenger and freight water transportation, they have no effect on
+the large vehicular traffic across the North River which must continue
+to be conducted by ferries until it can be otherwise provided for. As
+long as these conditions exist, ferry-boats must be used in large
+numbers and continue to obstruct the North River. This difficulty
+probably cannot be overcome by the construction of bridges, as in the
+case of the East River, but it does not seem too much to expect that,
+eventually, tunnels to provide for the vehicular traffic, like the
+Blackwall tunnel under the Thames, will be established under the North
+River.
+
+It would be interesting to estimate the increase in railroad traffic
+capacity resulting from these improvements, but the data required for
+this purpose are not available. Some idea of the increase in passenger
+traffic capacity resulting from the establishment of the tunnel line may
+be obtained by comparing the proposed daily train-movements for the new
+station with the train-movements at other important railroad stations.
+The daily train-movements of six such stations are given in the
+following table:

+
+ FOOTNOTES:
+
+ [Footnote B: Proposed train service when Station is opened, the
+ ultimate capacity of the Station being in excess of 1,000 trains per
+ day.]
+
+The freight capacity of the Pennsylvania System at New York has been
+greatly enlarged by the construction of the Greenville Yard and the
+facilities connected therewith, but it is impossible to estimate the
+amount of this increase. However, it is worthy of remark that, during
+the period from 1900 to 1906, the freight traffic density on the
+directly-operated lines of the Pennsylvania Railroad Company increased
+from 3,268,330 to 4,742,081 ton-miles per mile of road, a growth of
+nearly 50 per cent. Doubtless the improved freight facilities of the New
+York District had a large influence in the development of this increase.
+
+One of the most interesting points connected with this development of
+traffic facilities is its influence on the relative distribution of
+population in the different parts of the metropolitan district. In 1907
+the population per acre of the different divisions of Greater New York
+was reported as follows: Manhattan, 157; Brooklyn, 29; Bronx, 14;
+Queens, 3; Richmond, 2. The effect of new lines connecting some of these
+districts, and sections of New Jersey not far from the North River, with
+the business center of the city will undoubtedly be to increase greatly
+their population-density. It does not seem probable that the
+population-density of Manhattan will be sensibly reduced by these
+improvements, for they stimulate the increase of population, and
+apparently no increase of transportation facilities can keep up with the
+growth of the city. The population of a great commercial city must be
+congested near the business center. This is a necessary condition of its
+existence. All that can be done to meet this condition is to provide
+all possible facilities for moving the people into and out of the
+business districts and within its limits.
+
+During recent years the business population of the lower part of the
+Borough of Manhattan has become greatly congested. Very high buildings,
+providing business accommodations for large numbers of people, have been
+constructed, and these people must move to and from their working places
+at about the same times, that is, at the "rush hours" in the morning and
+afternoon, at the beginning and ending of the working day. Every effort
+has been made to provide for this immense and rapidly increasing local
+passenger traffic, by the construction of surface, elevated, and
+subterranean railways; but the demand for transportation has increased
+much faster than the facilities can be provided, and it is evident that
+the limit of down-town passenger traffic facilities has been very nearly
+reached.
+
+Apparently, the only remedy for these conditions is the movement of
+business and the people transacting it up-town or to the Boroughs of
+Brooklyn and Queens, which are now readily accessible by tunnels and
+subways. This movement, of course, is resisted by the great real estate
+and money interests centered in the lower part of the city, but,
+notwithstanding this resistance, the improvement has commenced and has
+rapidly advanced. The great retail houses are being established above
+23d Street; the banks and brokers' offices are rapidly appearing around
+the new business center of the city. The facilities afforded by the
+telephone and the subway for communication with the money center have
+doubtless greatly promoted this up-town movement.
+
+When the Pennsylvania Tunnel Extension is in operation, the easiest and
+quickest way for the passenger to reach the city from Newark will bring
+him into the Pennsylvania Station at Seventh Avenue and 33d Street. The
+schedule fast time from Newark to the New York Cortlandt Street Station
+is now 25 min. This may be reduced to about 18 min. by the use of the
+Hudson Company's tunnels, and while this involves inconvenience in
+changing transportation at Jersey City, yet it brings the traveler three
+blocks nearer Broadway. The time from Newark to the Pennsylvania Station
+will be about 17 min., and the trip will be made without change of
+transportation, so that, undoubtedly, by far the greater part of the
+Pennsylvania's passenger traffic desiring to reach the shopping and
+hotel center of the city will go to the new up-town station.
+
+The effect of the Tunnel Extension in increasing the volume and rapidity
+of the up-town movement and the real estate values will be very great;
+indeed, its influence is already apparent, although the line is not yet
+opened for traffic. With the extension of the present subway down town
+on the west side with direct connections to Brooklyn, and up town from
+42d Street to the Bronx, with connections to permit convenient transfers
+between these two straightaway subways--one on the east side and the
+other on the west side of Manhattan--the Pennsylvania Station will
+become a great center for receiving and distributing passenger traffic
+between all the Boroughs of the City and outlying points. The new post
+office to be established adjacent to the Terminal Station will also
+greatly assist in accelerating the up-town movement.
+
+In concluding this account of the New York Tunnel Extension project, the
+writer desires to pay a tribute of admiration and respect to the memory
+of the late A. J. Cassatt, President of the Pennsylvania Railroad
+Company, to whom the conception, design, and execution of the project
+are mainly due. His education and experience as a civil engineer, his
+thorough knowledge of all the details of railroad construction,
+operation, and management, gained by long and varied service, the
+directness, clearness, and strength of his mind, and his great executive
+ability, placed him at the head of the railroad men of the country. In
+the consideration of great problems, whether of transportation, finance,
+commerce, or political economy, he was almost unequaled, owing to the
+breadth, originality, and decisiveness of his character; yet his manner
+to his subordinates was so direct and simple that he seemed unconscious
+of his own superiority. Great as it is, the New York plan of improvement
+is only one item in a far-reaching scheme of development which became
+the policy of the Pennsylvania Railroad Company through Mr. Cassatt's
+advice and influence, yet his strongest interest was doubtless centered
+in the New York works. It is the sincere regret of all connected with
+the design and execution of the project that he did not live to see its
+completion.

+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:

+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work

+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.

+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and

+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+

+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from. If you
+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS', WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5. Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.

+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.

+page at http://pglaf.org
+
+For additional contact information:
+ Dr. Gregory B. Newby
+ Chief Executive and Director
+ gbnewby@pglaf.org
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card
+donations. To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
