BOSTON ELEVATED RAILWAY COMPANY - ELEVATED MAINLINE STRUCTURE (MBTA - ORANGE LINE)HAER NO. MA-14
The extant (1986) portion of the original elevated Mainline of the former Boston Elevated Railway Company (BERy) is located on Washington Street, in the South End, Roxbury and Jamaica Plain districts of Boston, Mass. and runs between the South Portal of the Washington Street tunnel and the Forest Hills Station, repair shops, and storage yards (Bents #1215 to #772). The original Mainline of the Boston Elevated Railway ran from Sullivan Square, Charlestown to Dudley Street, Roxbury and was later extended to the Forest Hills Station. The remaining structure consists of six stations. Bent numbers are indexed on plans in the files of the Massachusetts Bay Transportation Authority (MBTA) Engineering Department. Grid Coordinates refer to the Boston South Quad.

The Mainline of the BERy at one time consisted of six sections which traversed the congested areas of Boston and Charlestown to Roxbury and Jamaica Plain. For convenience these sections will be categorized alphabetically, according to their original loca tions, and hereafter will be referred to by Section letter. The main body of this report concerns Section F.
The sections are indexed on plans of the former BERy, MTA and the current MBTA. These plans have been included in this study as Fig. No. HD-1, HD-2, HD-3, HD-4, and HD-5.
This report with the accompanying illustrations was compiled to serve as a mitigatory documentation of this structure in order to comply with the requirements of the Memorandum of Agreement, signed February 1978 by the Advisory Council on Historic Preservation; Urban Mass Transportation Administration; and the Massachusetts State Historic Preservation Officer.
Formerly the Charlestown Division of the Boston Elevated Railway Company (BERy). Constructed in 1898-1901. Sullivan Square Terminal southerly through Charlestown to the North Portal of the subway. Included City Square, Thompson Square, North Station stations and the Charlestown drawbridge over the Charles River (built in 1896-1899 by the Boston Transit Commission). This section was abandoned in 1975 and was demolished in 1976-1977 when the new Orange Line subway was extended to Medford along the Boston and Maine Railroad right of way. Only Tower "C" was saved from demolition and moved to the Seashore Trolley Museum at Kennebunkport, Maine.
Extension of the Charlestown Division line easterly into Everett. Constructed in 1916-1919. Included only one station -- Everett (built by the BERy). Discontinued in 1975 and demolished in 1976-1978.
North Portal to Pleasant Street Station (now Broadway) via the outer tracks of the Tremont Street Tunnel which was adapted to elevated train use in 1901 by the construction of higher platforms. This 1ink was returned to full streetcar use in 1908 with the construction of the Washington Street Tunnel.
Pleasant Street Station, up the incline, over the Boston and Albany and New Haven Railroad right-of-way tracks, and along Castle Street as an elevated structure, to Tower "D" (Bent #1200) on Washington Street. Constructed by the BERy in 1901 to link the Washington Street elevated to the South Portal of the Tremont Street Subway. Abandoned in 1908. Demolished in 1935. Incline portion remained until demolition in 1961.
Elevated structure along Atlantic Avenue from Tower C at North Station to Tower D at Washington Street. Constructed in 1901 and in use until 1938. Demolished in 1942.
North Portal to South Portal via Washington Street Tunnel. Built in 1904-1908 by the Boston Transit Commission. This section will continue in use after demolition of the elevated structure.
South Portal to Forest Hills repair shops. This line was originally known as the Roxbury Division of the BERy. The line is divided for identification purposes into the following sub-sections:
South Portal (Bent #1215) to Tower D at Washington Street. Built in 1908 by the BERy to connect the new subway tunnel to the Washington Street line of the Roxbury Division. Structural system is plate girder bents with longitudinal plate girders.
Tower D at Bent #1200 to Bent #1143 south of Dover Street Station. Bui1t between 1899 and 1901 as part of the BERy Roxbury Division to Dudley Terminal. Plate girder bents with longitudinal truss girders.
Bents #1143 to #1068 along Washington Street. Built between 1899 and 1901 by the BERy. Includes Northampton Street Station. Arched truss bents with longitudinal truss girders.
Bents #1143 through #1100 to the Bartlett Street Yard. Built in 1899 to 1901 by the BERy as part of the original Roxbury Division. Includes the Dudley Terminal and the Guild Street yards and repair shops (discontinued in 1923). Plate girder bents with longitudinal truss girders. Loop around Dudley Station is marked by Bents T-l through T-28.
This section is the beginning of the Forest Hills Division. Construction work began on May 2, 1906 and service began on November 22, 1909. Work included rebuilding the loops and platforms at Dudley Street Station and the construction of Egleston Station. Section F-5 runs as an elevated structure from Bent #1000 to #797 at the Arborway yards. Construction is plate girder bents with plate longitudinal girders. was added on as a suspended structure in 1912. Green Street Station was added on as a suspended structure in 1912.
This section was a specially designed steel framework encased in concrete. Bents #979 to #783 include Forest Hills Station. Built in 1908-1909 by the BERy.
Bents #783 through #772 constitute the Forest Hills train storage yards and the repair shops. This extension was built in 1921. Repair shops built in 1923. Includes Tower "H". This section was demolished in 1984.
Dates of Construction:
Sections F-1 through F-4: 1898 - 1901
Sections F-5 through F-6: 1906 - 1910

Remaining portion of the original BERy elevated Mainline Structure is currently in use as part of the MBTA's Orange Line rapid transit service from Forest Hills to Medford, Mass. The elevated portion (Section F-1 through F-7) serves from the South End through Jamaica Plain. The entire structure is slated for demolition when the new Southwest Corridor segment of the Orange Line rapid transit is completed.
This portion of the Orange Line elevated is historically significant as Boston's first elevated line, built during a period of world-wide interest and experimentation with elevated railways; and as the product of Boston's last privately-owned transit company, the Boston Elevated Railway Company.
Architecturally, it is significant for the quality of its original station architecture, which was designed by the prominent local architect, Alexander Wadsworth Longfellow. Later alterations were carried out under consultation with other leading Boston architects, such as Robert Swain Peabody and Edmund Wheelwright. In general, it represented the most advanced transportation planning of its day and is a good case study, on a small scale, of rapid transit at the turn of the century.

Chapter 1 Introduction and Significance of the Orange Line Elevated
Ever since Boston's earliest days Washington Street has been the main route for transportation between Boston and Roxbury and all other towns in the southwest portion of the larger city. The earliest stagecoach followed by the omnibus and later by horse-drawn and then the electric streetcar all used this route that was to become so heavily travelled that by the 1880's it had become imperative to build an elevated railway to provide rapid transit north and south of Boston. This section of the elevated structure from Dover Street to Forest Hills is the last remnant of a larger system of elevated railroads that served Boston at the turn of the century. Boston was one of the last major American cities to build an elevated rapid transit line.
The system was developed first in New York City and refined in Chicago, where third-rail electric motive power was first used.
Because it was built comparatively late, the Boston Elevated structure could use advanced rapid transit technology borrowed from many different sources. It is today a good case study, on a small scale, of the "State of the Art" of rapid transit at the turn of the century.
The Orange Line is significant not only from the point of view of techno1ogy but it also represented the most advanced transportation planning of its day. The BERy was the first company in the United States to include subways, elevated transit and surface trolleys -- all operating under one management. In contrast to a system with many competing lines and companies (the usual situation in most cities), the public could transfer from one section to another of the BERy without paying more than one fare.
The early history of the Boston Elevated Railway and the Orange Line illustrates how Boston avoided the excesses of both total public control and free-wheeling private enterprise. All major cities building transit systems at that time had such problems in common, but in Boston a balance was struck: private management ran the system but government regulated it and also built the subways.
Although it was a small system, Boston's distinctive topography caused many difficult planning and engineering problems. Narrow curving streets, high density in the downtown area, limited arteries into the center of Boston, the hilly terrain, the Boston Common and Public Garden, and settled residential districts made the task difficult for the Civil Engineer. Contemporary descriptions of the system continually extolled the work. It remains today an impressive undertaking. By studying this system today, we learn on a modest scale about the problems of other transit systems of that era. We can also more fully appreciate the engineering capabilities that built this system.
Chapter 2 History of Public Transportation in Boston
Unti1 the mid 19th century, Boston was a peninsula surrounded by water on three sides and connected to Roxbury on the south by a neck of land. Cambridge to the west and Char1estown to the north, connected to Boston by bridges, were the only other important communities. People lived close to their work and rarely travelled beyond their own communities. Except for private coaches and horses for the well to do, stagecoaches, omnibuses and, later, trains were the only methods of distant travel.
The omnibus, a horse-drawn bus with a rear entrance, was the first form of public transportation running on a regularly scheduled basis. In 1826 the first omnibus line in Boston opened. This ran to Cambridge, and by 1830 there was a similar line to Roxbury. Both were privately operated.
These early omnibus lines used approximately the same routes as at least two of the major branches of Boston's later public transportation system: The Red Line serving Cambridge/Boston and Orange Line serving Roxbury/Boston/Charlestown (HP-1) (For explanation of illustration designations, see Notes, Chapter 2.)
In 1856, the first horse-drawn street cars were introduced from Harvard Square, Cambridge to Bowdoin Square, Boston. Although steam railroads had been operating since the 1830s under charters from the Massachusetts Legislature, their service was limited largely to routes between cities and towns. By the middle of the century, Boston's population had increased greatly and there was a pressing need for rapid transit within the city.
The first such company was the Cambridge/Boston Company (1856), followed by the Metropolitan Railroad Line. This change underscored the evolution of Boston from a compact mercantile city to a larger one fed by the suburbs. Horse railways operating under a public franchise offered a faster and more comfortable ride than the omnibus. Under Massachusetts law, a franchise was a revocable right, granted by a municipality, to operate over public roads; thus the public had some control over the privately operated horse railways.
The Legislature and the Boston City Council subscribed to the then universal belief that free competition among many companies on public streets would provide the best service for the general public. In most large cities, especially New York and Chicago, there were many independent lines spread out over a wide geographical area. In spite of municipal corruption, the traction franchises still ensured reasonably good public service.
In Boston, because of local topography, the situation worked out differently. All traffic from the north and south was funnel led into the downtown along the two main downtown streets: Tremont and Washington. As Boston's population and business district grew, the surrounding towns became bedroom suburbs, and in turn caused the public transportation system to become overloaded.
By 1865 there were four main horse street railways:
- The Middlesex Railroad - serving the North (Charlestown);
- Union Railway - serving the West (Brighton, Cambridge, Somerville, Watertown, and Arlington);
- Metropolitan Railroad - serving the Southwest (Brookline, Dorchester, Roxbury, West Roxbury);
- South Boston Railroad - serving the South (South Boston, Dorchester).
In 1872 and 1881, the Highland Street Railway, serving Roxbury and Dorchester, and the Charles River Railway, serving Cambridge and Boston were established.
The lines were largely independent, and there were few crosstown lines or transfers. In the congested downtown area, the lines had to share a few tracks along Tremont and Washington Streets (HP-2, HP-3). Fragmented service and competing lines were not the answer to Boston's expanding business growth and population.
By 1860, traffic was 50 million riders, and, in 1885, it had climbed to 80 million. All large American cities had similar transportation problems and tried various solutions. In 1873, the cable car was invented in San Francisco and quickly was adopted in New York, Chicago and Washington, D.C. The horse-drawn street car had reached the limits of its effectiveness. It could not travel long distances at a high speed or carry heavy loads of passengers, and the cost of maintaining large stables of many horses was becoming prohibitive.
The cable car was the first practical method of increasing the effectiveness of mass transportation. Although the cable cars worked well in cities with broad straight avenues, they were not feasible on Boston's crowded streets, which had to carry several lines.
In Berlin, in 1881, Werner Siemens put into operation the world's first electric streetcar. This was followed by various attempts by Charles Van Depoele and Leo Daft in the United States to develop a workable electric streetcar.
The rapid development of technology in the 1880s provided a solution. The first practical electric streetcar system was realized by Frank Julian Sprague in Richmond, Virginia in 1887 -- a major step in transit history.
Meanwhile in 1886, Henry Melville Whitney, Eben Jordan and others had purchased a vast amount of land along Beacon Street in Boston and Brookline to develop as real estate. They also chartered the West End Railway to provide street car transportation into Boston. Whitney soon realized that a11 seven of the then competing roads would have to be combined into one economical line. His strong financial backing and his political role as an enlightened Democratic business man gave him the legislative support to create the requisite transit monopoly in Boston and its major suburbs.
Whitney, in less than a year, had organized the seven separate lines into a single integrated transit system using the "division system" of organization employed by major railroad companies. The best executives from the old lines were placed in responsible positions within the new company.
Frank L. Sprague's success with the electric street car in Richmond, Virginia convinced Whitney that electric traction was the solution to the shortcomings of the horse cars. He electrified the Beacon Street Line of the West End Railway in 1887, making Boston the first major city in the world to employ electric streetcars. By 1892, the trolley cars accounted for two thirds of the city use, and, by 1894, more than 90% of the lines were electrified (HD-100).
Contemporary accounts describe the progress of the West End:
Within a single year this company, through the financial genius of its organizers, had accomplished the consolidation of all the great street railway companies of the city, operating 231 miles of track, the largest street railway system in the world.... It is probable that more problems of mechanical engineering and of railway administration have been grappled 'ab initio' by this one company than by any other team of street railway companies in the last fifty years. 
Although the West End provided excellent transit service, there were still prob1ems. Ridership kept increasing, and the number of persons and streetcars going into downtown Boston began to choke the downtown streets again. There were many proponents of an elevated railroad to provide rapid transit. This had been the solution in New York City, where the first elevated railroad powered by steam locomotives was built. Chicago, another city with broad, long avenues, also had a network of elevated railroads beginning in 1892. Most Bostonians did not want the noise and ugliness of elevateds in downtown Boston, but the residents of outlying sections of the city were in favor of an elevated railroad that would shorten travel time into Boston. Charles Cheape has chronicled the complex struggles that went on in Boston as the public sought a solution to the traffic jams in downtown Boston. 
In 1891, the Legislature set up a Rapid Transit Commission to resolve the transit impasse. After many hearings and much research, the Commission made several recommendations for Boston's future transportation system. Three recommendations were especially important:
- North and South Stations should replace the numerous railroad stations then serving Boston;
- An electric streetcar subway should be built under Tremont Street;
- A system of elevated and subway lines should be built to Char1estown, Roxbury, Cambridge, and Boston.
Stat. 1894 Chap. 548 -- An Act that incorporated the Boston Elevated Railway Company (the "Meigs Charter") and authorized numerous transit routes in the Boston Metropolitan area -- was the first regional approach to mass transportation. Later Acts were:
- Stat. 1895 Chap. 440 -- An Act that authorized the construction of subways in the City of Boston;
- Stat. 1896 Chap. 492 -- An Act that placed limits on the West End Railway in its use of the subway;
- Stat. 1897 Chap. 500 -- An Act that authorized the Mass. Railroad Commission to use other systems besides the Meigs. This law also:
- a) Authorized construction of the Cambridge Subway;
- b) Laid out routes of a proposed elevated railway;
- c) Gave the Mayor of Boston authority to review and approve architectural and engineering plans of an elevated railway;
- d) Established a five-cent fare with right of free transfer;
- e) Required that the elevated railway run through a subway in the center of Boston;
- f) Authorized construction of a new rapid transit bridge from Boston to Cambridge across the Charles River;
- g) Authorized construction of a rapid transit tunnel to East Boston under Boston Harbor;
- h) Declared franchise rights of the BERy to be irrevocable.
This was an unusually comprehensive and well thought out law that resolved most of Boston's transportation dilemmas. From this point on, good public policy and sound traction management were to be characteristic of the city's transportation system for many years to come.
After Henry Whitney left the West End Railway in 1893, that company lost its strong direction and failed to take advantage of the new legislation. A competing group of financiers headed by J. P. Morgan bought out the old Meigs franchise through the Boston firm of Kidder Peabody in 1895. The new directors had the requisite backing to finance construction of the "Elevated." They also proved able to overcome the public's objection to the structure. After some maneuvering, the Morgan group bought control of the West End, which, on December 9, 1897, was absorbed by the Morgan run Boston Elevated Railway. The new BERy now had both a financial and legal monopoly over most public transportation in Boston and its suburbs.
The Act of 1897 also resolved the dispute over the location of the Elevated structure. In 1895, the Boston Transit Commission had begun construction on the Tremont Street Subway, which opened on September 1, 1897. The new charter allowed the BERy to use the Tremont Street Subway for its elevated trains. This solution prevented the disfigurement of downtown Boston by elevated tracks while providing for their construction in the outlying suburbs of Roxbury and Charlestown.
The creation of the West End Railway and the BERy had understandably caused many reform minded individuals, led by Louis D. Brandeis, to fear that these giants would abuse their potential monopoly powers. It was a complex dilemma. There was little confidence in the ability of the often corrupt municipal governments to operate public transportation. Therefore the prevailing sentiment favored private enterprise. Yet only a company with near total monopoly powers could operate rapid transit systems effectively. Boston's eventual solution of pub1ic and private control was unique in the United States.
In other major American cities, traction companies managed to wrest total control from the public. By contrast, in Europe, muni cipal governments subsidized and completely controlled public transportation.
In Boston, the public component was the Boston Transit Commission chartered by the State Legislature. The Commission built the subway and leased it to the BERy to be used by its rolling stock. Thus the major capital expenditures for subway construction (more costly than an elevated structure but more desirable for use in the downtown area) would be undertaken by the City of Boston using its lower interest rate on bonds. The BERy, with the approval of, the State and the City, then built the elevated structure and connected it to the subway. With its impressive financial resources, it could build the structure, the stations and the outlying street lines and operate the entire system. The public benefited because the monopoly was partially under control of the electorate. The individual rider benefited more directly from the five-cent fare and the right of free transfer.

Construction of the Elevated Structure 1898-1901
Once the legal problems surrounding the granting of a clear charter to the
Boston Elevated Railway and its franchise to build a third-rail, electrically operated, elevated rapid transit system (using the then new multiple unit cars)
had been resolved, the management of the BERy immediately began planning work for the proposed elevated structure.
George A. Kimball (1850-1912), a respected local civil engineer, was
appointed chief of the Engineering Division to plan, design and construct the
Kimball had served for eleven years as chief engineer for the
City of Somerville and had gone on to distinguish himself as the engineer for
the Metropolitan Sewage Commission.
I n the 1880 I s thi s agency had been pri-
marily responsible for building a vast regional sewage system for metropolitan
Boston -- a major civil engineering feat for its day.
Under the terms of Chap. 500 Acts of 1897, the BERy was fi rst requi red to
submit plans of the route to the Massachusetts Railroad Commission, which at
that time was empowered to supervise all railroads and street railways, for
review and approval.
The plans then had to be approved by the Mayor and Common
Council of the City of Boston.
The main public criteria" were that the structure be light and airy and that
the stations be of superior architectural appearance.
Although New York City
had been constructing and operating elevated railways since 1873 and Chicago

since 1885 (HP-4), Boston was just now accepting this already standard form of
New York's system of steam locomotives pulling wooden railroad
cars had not impressed Bostonians.
The structure of the New York Elevated
(HP-5, HP-6), though elegant and open in the early stage of development, became
less attractive as solid plate girders were used in the later extensions.
combination of noisy, smoky, dirty trains runnning over structures that blocked
out the sunshine on the streets below was something that Bostonians wished at
a 11 costs to avoid.
Moreover, with its sophisticated architectural and civil engineering forms,
the Berlin elevated railway system set a standard of excellence which Bostonians
tried to achieve (HR-14). 
The BERy executives made every effort within
their limited budget to avoid the mistakes of the New York systems and to emulate the successes of the Germans.
The basic design of the elevated structure was quite similar to the one
developed in New York City (HP-7) and later perfected in Chicago.
The prel imi-
nary designs were done under the direction of J.A.L. Waddell, who had been pri-
marily responsible for the design of the Chicago system.
The structural and
civil engineering work was done by the Engineering Department of the Boston
El evated Railway Company.
(Chapter 6...Structural Analysis and Description of
the Elevated Structure discusses in greater detail the engineering aspects of the elevated structure.)
In general, the tracKs were laid 24 feet apart on center except on narrow
streets where they were 12 feet apart (HD-15).

sections spiked to hard pine ties 16 inches on center, which in turn were bolted
to the steel structure.
Every fourth tie was extended out to support a sidewalk
for track maintenance men.
The trackwork was supported on bents consisting of
steel columns supported on heavy concrete foundations.
Heavy cross girders con-
nected the columns and longitudinal gi rders with cross bracing supported the
After a long design review process, the final approval for the system
came on April 29, 1898.
Construction began on the Dudley Station site on January 23, 1899. Property condemnation proceedings had already commenced allowing for demolition
of any structures in the way. Contracts for steelwork along the Roxbu ry Division were awarded primarily to the Pencoyd Bridge Co. of Pencoyd
Pennsylvania, a noted bridge building company, which already had considerable
experience with the then new steel technology of fabrication and construction.
Other steel work was executed by the Carnegie Steel Co. and the Pennsylvania
Terry and Trench Co. of New York City were selected as general
contractors for the steel erection primarily because of their experience in
putting up elevated railroad structures in New York City.
While construction on some parts of the Elevated, in Charlestown and on Pleasant Street and Atlantic Avenue (HP-26, HP-27), was carried on in a normal
fashion during the day, most of the work on the Washington Street segment was
done at ni ght.
While efficiency and speed were considerations, the main reason
was to avoid touching the live wires that fed the trolley cars running along
Washi ngton St reet.
(The lines were either removed from the portion under
construction at night or else the power was cut.)

The BERy specifications stipulated that, wherever there were surface tracks, materials should be delivered to the narrow portions of the streets each
evening after 7pm and that construction could take place only between the hours
of midnight and Sam.
Co 1 umns and gi rders were fabri cated in the 'shops of the
bridge companies doing the work, delivered by railroad car to the nearest
siding and finally hauled to the site by trucks pulled by horse teams (HP-24).

Dover Street (HP-19).
After the cross members were in position, a traveller was
installed to lift succeeding bents into place.

was set into place and the longitudinal girders attached, the traveller pulled
itself forward along the tops of the girders on rollers to the next stop and installed the next section (HP-2l, HP-22).
The work was carried out in five segments (HD-l): a.) The Charlestown Main Division;
b.) The portion over the Charlestown Bridge which itself had been built in 1895 by the Boston Transit Commission;
c.) The conversion of the Tremont Street Subway, which originally consisted
of four tracks for streetcars and was modified by the BERy to allow use
of the high platform third rail trains on the two outside tracks;
d.) Building an inclined connector between the tunnel portal at Pleasant
Street across the Boston and Albany Railroad tracks and Tower D at
Washington St. (HP-9, HP-ll, HD-5);
Boston Elevated Railway Company HAER No. MA-14 Page 28
e.) The construction of the Roxbury Main Line along Washington Street (now called the elevated portion of the Orange Line) to the terminal at
Dud 1 ey St reet.
The line was planned as an elevated rapid transit railway between several stations spaced at long intervals for passengers arriving by surface streetcars.
Since Boston streets were too narrow to allow more than two tracks, the New York
and Chicago system of four-track lines consisting of express trains and local
trains was not used.
Since the BERy also had the unique advantage of
cont ro 11 i ng all 1 oca 1 1 i nes with the ri ght of free transfer, the system of a
limited number of stations spread far apart was feasible.
The Roxbury Division
was planned to service local lines at Dover Street, Northampton and finally
These street car lines served Brookline, Newton, Dorchester, Roxbury,
Jamaica Plain, South Boston, and connected to other companies serving com-
munities to the southwest of Boston as far as Walpole.
Li nes that formerly ran
into downtown Boston either along the streets or, after 1898, through the
Tremont Street Subway were now serviced by the Elevated, thus cutting down the
time of travel.
Construction on the Castle Street/Pleasant Street connector began in the
fall of 1900 just as the work on the Pleasant Street portal and the new viaduct
was mostly done.
Construction photographs show the rapid progress of steel
erection during Oecember 1900 and January 1901.
To accommodate the longer
multiple unit, three car trains inside the Tremont Street Subway, the outer two tracks were converted to third-rail use; and, inside each Subway station, high
wooden platforms were erected to allow direct access to the trains.
Si nce the
Boston Elevated Railway Company HAER No. MA-14 Page 29
Subway had been designed with short trolley cars in mind, some of the radii were too tight, and certain walls and platforms had to be modified to allow clearance
for the new trains.
Most of the conversion work was done in the Subway in the
week prior to the opening of the new elevated line in order to minimize obstruc-
tion to trolley cars uSing the Subway (HP-12, HP-13, and HP-18).
Steel erection on the Washington Street section began on AU9ust 19, 1899,
and, by December 20, 1899, the structure had been erected as far as Sterling
Street -- a remarkably fast performance by today's construction standards.
1980, a modern flat plate girder replaced the existing trussed girder to allow
for the passage of the new Melnea Cass Boulevard under the structure (HP-40,
Project planning was done under what we now call a fast-track method.
soon as planning approvals were obtained, structural design and detail drawings were begun, and contracts were signed with steel companies for the required ton-
nage of steel.
First column foundations were poured.
Erection of the structure
began as soon as possible.
The main line structure was already up while archi-
tectural drawings for the stations were being completed.
A completion date of
December 1900 had originally been scheduled but was delayed a few months.

Dover Street Station was built in 1900 as a center platform type of struc-
Like Northampton Street Station, it was designed to be used by four-car
trains. After the opening, traffic on the elevated line was so heavy that the BERy decided to lengthen the station platforms to accommodate six-car trains
originally and eight-car trains later (HP-30, HP-31, HD-50 through HD-54).

The same plan shows that the center platform and waiting room were
eliminated (HD-58). When work was completed, the platform had been lengthened
to accommodate an eight-car train.
While the new pavilion with waiting room and change booths on the inter-
mediate level with the enlarged station meant a more functional plan capable of moving large numbers of passengers from streetcars to elevated train, the final
architectural configuration of the station that emerged was clearly inferior to
that of the first.
In April 1911, plans were issued for the erection of a temporary Oover
Street Station built of wood that would temporarily replace the regular one
while the complete renovations were under way (HP-32). [2J
Boston Elevated Railway Company HAER No. MA-14 Page 31
Northampton Street was built according to plan and opened in 1901 and remains today as the only station that has undergone little change other than
the lengthening of the platforms to accommodate six-car trains in 1908 (HP-34,
HP-35, HP-36, HP-37, HP-39).
Dudley Station Dudley Station was conceived as the southern terminal of the Main Line.
Storage and repair yards were built at Bartlett Street, and a three-track spur
extended from Dudley station along Washington Street to join them. The terminal
itself was a complex tri-level combination of elevated train platforms and sur-
face and intermediate-level platforms for transfer to street cars. This terminal serviced all the streetcars coming to Dudley Station from Jamaica Plain,
Roxbury, West Roxbury, and parts of Dorchester.
Southbound tra ins from Su 11 i van
Square would arrive at Dudley, go around the loop, and pull into the northbound
platform to unload and load passengers.
These passengers came from streetcars
that rode up the inclines feeding the east and west loops which acted as
passenger platforms (HP-77).
On the surface level, there were other surface
lines bearing passengers.
All these surface lines could take passengers as far
out as Dedham, Westwood and Walpole(HP-41 through HP-50). 
The communities to the southwest of Boston were now more populous, and the
original spine of Washington Street to Roxbury (now called the "Orange Line")
extended beyond the Boston city limits.
By 1900, the BERY decided to build a
separate tunnel under Washington Street to connect the two ends of the Main Line
with a direct link.
Also the Tremont Street Subway could be returned to its
former use as as streetcar subway.
The Acts of 1903, Chap. 534 authorized the
Boston Elevated Railway Company HAER No. MA-14 Page 32
Boston Transit Commission to build the tunnel and lease it back to the SERy, which would in turn furnish the tracks and operating equipment.
In retrospect, this decision seems wise.
In its implementatlon, it repre-
sented another stage in the continuing struggle between the management of the BERy and the reform elements in Boston who feared the monopolistic potential of
such a huge corporation.
While the construction of the tunnel was done by the
Boston Transit Commission, the interiors of the tunnels and the station fur-
nishings were the responsibility of the SERy.
The designs for the interiors and
entrances were carried out under the direction of the noted Boston architect
Robert S. Peabody.
The tracks and related equipment were designed and installed
by the Engineering Department of the BERy under George Kimball.
connection from the South Portal to the main line at Tower 0 (HP-16, HP-17) were
also the responsibility of the BERy's Engineering Division as was the super-
vision of construction.
The design of the tunnel station platforms allowed the
use of eight-car trains along the entire line, and plans were undertaken to
1 engthen the pl at forms at all stations.
During 1903, the BERy decided to extend the elevated structure to Forest
Again approval was sought from the Massachusetts Railroad Commission,
which held the requisite public hearings, and from the Mayor and Board of
Aldermen of the City of Boston.
The approval for the structure with locations
of stations was received on January 4, 1904.
Soon after that date, engineering
drawi ngs were undertaken.

Commission and by the City of Boston, and construction began on May 2, 1906 with
the erection of the first bents at Guild Street (HD-37). 
The same system that had been used earlier on Washington Street -- bents
delivered to the site during the day and set in place by the traveller at night
-- was employed.
Numerous construction photographs and drawings illustrate how
the work progressed and reveal the methods of steel erection and track laying
at that time (HP-78 through HP-90).
Again, progress in steel erection was rapid.
By late August of 1906, the
traveller had reached the Egleston Square station area and, by January of 1907,
the structure was approaching Forest Hills.
At this point, the chronology be-
The BERy annual report of December 31, 1906 notes that the com-
pany had not yet received approval for plans for new stations at Egleston and
Forest Hills nor the changes at Dudley.
Presumably, the management was preoc-

cupied with the extra work on the Washington Street Tunnel and the numerous other projects then starting in Cambridge and East Cambridge.
Robert S. Peabody's daybooks for 1907 indicate that the BERy's committee of
architectural advisors met repeatedly during that year reviewing designs, not
only for Forest Hills Station and the Arborway crossing, but also for the
Causeway across the Charles River to East Cambridge. 
By early 1908, the
designs for all stations had been approved, and work resumed on the elevated
structure crossing the Arborway and on the Forest Hills Station itself.
Peabody, the chief architect to the BERy, appears to have decided to have a
line of single massive piers supporting the main line structure.
At this point,
where the structure crossed the Arborway, the piers would be encased in concrete
and made to look like rough hewn stone.
Peabody and his committee of architec-
tural advisors chose the same solution for the BERy crossing over the Charles River Dam (the Lechmere extension), which was designed at the same time.
The crossing of the Arborway (HP-103) was a particularly sensitive design
problem, since the architects wished their structure to harmonize with both the
landscape design of Frederick Law Olmsted and the nearby Forest Hills Railroad viaduct, a massive granite bridge designed by Shepley, Rutan and Coolidge from
preliminary plans by the landscape architects and constructed approximately ten

The new design for Dudley Station took an already sophisticated multi-level
scheme and enhanced it.
A new southbound platform for trains going to Forest
Hills was constructed over Washington Street along the West Loop of the ter-
The mainline continued out toward Guild Street and along Washington
Street to Egleston Square.
Two new pedestrian bridges connected a new south-
bound platform with the existing terminal.

1900 was lengthened to receive the longer eight-car trains (HP-74).
At the same time, nUmerous changes were made on the surface level.
most interesting additions consisted of the two pavilion-type waiting rooms that
were placed inside the old loops (HP-70).
The trolley loops were also enclosed.
Work on the new platform began in the summer of 1908.
November 22, 1909 was the
opening date for extended service from Forest Hills to Sullivan Square.
know that heavy steel work was still in progress under the southbound platform
after that date.
Progress photos show that, while the new platform and bridges
were almost complete, work on the framing of the new loop enclosures was just
beginning in October of 1909. Work on Dudley Terminal was essentially completed
by the summer of 1910, but final roofing was still being done in September of
that year (HP-61 through HP-68).
Dudley Terminal has always been a busy area, and minor changes have
constantly been made in the interior to improve passenger flow and expedite
movement of transit vehicles.
In 1948 the east pavilion was completely rebuilt
to allow use of the trackless trolleys that were replacing the old electric
streetcars in the Roxbury/Dorchester area.
The center pavilion was removed and
a new roof with factory skyl ights installed.
Gradually the service at the West

In the early 1970's, that loop was completely demolished.

Forest Hills Station was an extension of the Arborway crossing of the main
1 i ne.
Designed by the architect Edmund S. Wheelwright, a member of the advisory
committee, under the direction of R.S. Peabody, it was framed of heavy steel
encased in concrete.
The BERy built an extension of the regular steel bent
construction system, beyond the station, to allow trains to reverse direction over a diamond shaped crossover. This work also included construction of a
spur-track incline out over the present Arborway yards for storing trains.
November 5, 1921, the Forest Hills station structure was extended southward. A
storage yard was built, and the Arborway inclined yard was removed.
By 1923, a
Boston Elevated Railway Company HAER No. MA-14 Page 38
new car repair shop had been built which replaced the smaller shops and storage
yards at the Guild Street yard (HP-104 through HP-ll7). 
Green Street Stat ion
When the BERy submitted its first proposals for the Forest Hills extension
to the Mass. Railroad Commission, the plans included a site for a passenger sta-
tion at Green Street, but that particular location was not utilized at first.
It was only after the extension had been opened that the BERy decided to build
Green Street Station in 1910. The simplest construction method was used: a
suspension system of hanging the lobby from the bottom of the tracks and
building a steel-frame concrete platform with canopy on top of the structure. The station was completed and opened in 1912 and served as a local station for
commuters from the neighboring sections of Jamaica Plain (HP-98, HP-99).
Egleston Square Sub-Station The extension of the Main Line to Forest Hills required the construction of
a sub-station at Egleston Square for the conversion of alternating current
generated at the South Boston Plant to direct current for use in this portion of
the rapid transit system.
The station was designed by Robert S. Peabody and
consisted of a steel framed building to house the sub-station equipment.

Architectural Description of the Stations
The orginal way stations of the Boston Elevated Railway were conceived as
parts of a single theme, designed by a single architect, and constructed over a
short period of time.
They refl ected a much more uni fi ed concept than the
stations that stand today.
Indeed, the winning design submitted by Alexander
Wadsworth Longfellow, Jr. (1854-1934) was often illustrated in trade journals by a single, "typical station" (HP-8). 
The style of each station was "early French Renaissance," combining classi-
cal and Gothic features in true Beaux Arts fashion.
The result, everyone
agreed, was appealling for the "I ightness, symmetry and beauty" of the stations
themselves and of their relationship to the graceful, web-like structure that
weaved over the streets of Boston.
The "typical station" of 19D1 dotted the original line between the Sull ivan
Square and Dudley Street terminal stations.
Subsequent alterations have
obscured the original Longfellow design. Of the "Roxbury Division's" first sta-
tions -- Dover, Northampton and Dudley Street stations -- only Northampton Street
has retained its original character.
It reveals perhaps the most enduring merit
of the original design:
stations of competent but unremarkable design, which
were adapted in every sense to thei r site:
the elevated structure.
The qual i-
ties that are aesthetically noteworthy in the elevated structure -- the sense of
motion, light and air; the expressive, curvilinear grace of the truss-work;
Boston Elevated Railway Company HAER No. MA-14 Page 41
subtle adaptations to the site; rhythmic, elegant arches and carefully crafted details -- are also found in the stations.
DOVER STREET AND NORTHAMPTON STREET STATiONS
Dover Street and Northampton Street Stations were originally "island" stations, perched between two tracks on top of the elevated platform, enclosed
in rectangular huts with Renaissance details.
Northampton Street Station was
approximately 12 1/2 x 40 feet long, and Dover Street station was slightly
Each had a covered platform 160 feet long, and was sheathed in copper
panels and capped by an overhanging copper-paneled ridge roof brindled with
standi ng ri bs.
Standard features were three dormer windows and a central Beaux
Arts cupola flanked by two finials, one over each gable.
On the east and west
elevations, a band of sash windows (configured slightly differently at Dover and Northampton Street Stations) was surmounted by a diamond-paned clerestory and
separated by copper paneled pilasters decorated with a diamond motif.
di amond motif was repeated on the copper panel s just beneath the windows and
pilasters (HD-52 through HD-63).
The stat ions were reached by means of iron stai rways of approxi mate ly 38
steps, covered by a running copper canopy that was ribbed like the station roof.
Each landing was covered by a copper pavilion roof supported on four posts and
decorated with a copper finial.
A wrought iron balustrade enclosing the stair-
way on either side was decorated with scrolls and copper panels.
At the first landing, the passenger entered an arched double door with
diamond-paned lights and semi-circular transom.
The second flight of stairs led
Boston Elevated Rai lway Company HAER No. MA-14 Page 42
directly to the waiting room lobby, where the passenger purchased his ticket at
the ticket office.
He waited for the train inside the waiting room (similar to
HP-38) or outside the station on a canopied platform.
(When he disembarked on
the opposite side of the platform, he descended a connecting exit stairway which
led directly to the street.)
The station interiors were sheathed in oak, with hard pine for the floors
in both the station rooms and platforms.
The furnishings, also designed by
Longfellow, included a ticket office, turnstiles, wooden benches, porters' clo-
sets and rest rooms.
The ticket offices, octagonal or semi-octagonal booths
that stood in front of the entrance stairs, were distinguished by their classi-
cal detailing, elaborate iron work and varied materials.
To either side of the
ticket window were arched, sash or spring-balanced windows.
ticket window were a keystone and scrolled, wrought-iron grille. A thick marble
slab served as the ti cket ledge.
The lower portion of the office was sheathed
in wood and copper, and stood on a base of wood and Tennessee marble.
Station the ticket office was originally crowned by an oak balustrade with
knobbed posts above a paneled architrave.
In the early days of operation of the
trains, passengers first bought a ticket and surrendered it at a turnstile
(HD-61, HD-62, HD-63).
In the center of the room were a pair of back-to-back wooden benches. Beside these were the rest rooms and porters' closets. Oak sheathed the interior
walls and separated the sash windows.
The ceiling, also sheathed in oak, was
patterned in the center panels with the diamond motif. Incandescent and arc
lights illuminated the interior (HP-38).
Boston Elevated Railway Company HAER No. MA-14 Page 43
The platforms were notable for the quality of their engineering details.
Dudley Station, the southern terminal until 1909, was designed to harmonize with the way stations, punctuate the elevated railway with a strong design, and
meet the requirements of its function as a turn-around, transfer station and
junction of several surface lines.
Its complex vehicular circulation was
explained in a Boston Elevated Railway Company publication:
The rapid-transit track passed through the center of
the station, with a loading and unloading platform on
Surface cars reached the same level as that
of the rapid-transit platforms by easy inclines, a loop
track being provided on either side of the station so
that transfers between surface cars and rapid-transit
trains could be readily made.
Through cars ran through
the lower level of the station and the upper level was
reached by an adequate number of sta i rways. 
The elevated platforms to either side of the station were covered by copper
canopies which flanked the station below the clerestory and extended north on
the east and west sides.
The central, rapid-transit entrance on the north end
was arched and flanked by stairways which led to the surface level.
surmounted the station's ridge roof; and a finial stood on each gable (HD-64
th rough HD-69).
Boston Elevated Railway Company HAER No. MA-14 Page 44
To either side of this entrance were enclosed waiting rooms. each 18 feet
square and surrounded by paired, sash windows with diamond-paned upper sashes
(HD-70 through HD-73).
The exterior elevation was framed by a row of copper panels
and pilasters embellished with the diamond-triangle motif.
Set in the north-
easterly and northwesterly corners of the station, these waiting rooms were entered
via the elevated loading platforms under the station's main roof.
featured a ribbed mansard roof and an entrance decorated with classical ornament, a
tympanum with a paneled roundel, a scrolled arch, and a finial.
The interior was
paved with terrazzo.
The central loading platform was spacious, elegant and richly furnished. In addition to the two enclosed waiting rooms, it housed a magazine and tobacco
stand (HP-49), storage rooms, a ticket office, public toilets, built-in wooden
seats and, to either side of the platforms, wrought iron stairways leading to
the central waiting room, just below track level.
An oak ceiling was carried on a series of open steel trusses gracefully
arched and supported below the clerestory on copper brackets.
The a rch theme
was continued in the station walls, which were open to the unloading platforms
outs i de the stat i on vi a an arcade cons i st i ng of uncovered steel columns and
copper-paneled arches springing from copper brackets.
The a rches we re

these were rectangular paneled spandrels with a triangle/semi-circle motif, and
a clerestory of diamond-paned sash windows (HP-50, MA-14-36).

was an octagonal room, approximately 160 feet in diameter.
it featured an oak dado with stone mouldings, buff brick walls, a maple floor
and a coffered oak ceiling.
In 1909 Dudley Street Station was altered to provide for separation of
loading and unloading traffic, and for the accommodation of eight-car trains. The east and west loops were rebuilt, each containing a polygonal waiting room

loading and unloading platforms were built, accessible by new covered bridges
with stairway connections (HP-68 through HP-74, HD-73, HD-74).
A reinforced concrete bus loop was built in 1948 to accommodate the
trackless trolley (MA-14-32, MA-14-33).
Egleston Station, built in 1909, was the first station in which the plat-
forms, galleries and stair landings were designed for reinforced concrete

The des i gn
was a simplified, unembellished version of the original Longfellow station; a
rectangular structure, 44' x 22' with a half copper ribbed roof, windows,
pilasters and copper panels (HD-81, HP-94, HP-95).
More decorative emphasis was
given to the platform, which was positioned above the station on the second
1 eve 1.
It featured a ribbed copper canopy supported on iron columns and a
gallery with arched, sash windows and keystones, which the passenger entered via
a waiting room stairway (HP-96, HD-81).
The waiting room contained an alcove on
the west side, wooden benches, and an octagonal ticket office which was sheathed
in copper, finished in white ash, and detailed similarly to the original ticket
The floors of the waiting room, platform and gallery were of rein-
forced concrete (HD-82, HD-83).
In 1916, an enclosed footbridge with a patterned ceiling was constructed to
connect the original station to a surface car station (HD-84, HD-85).
GREEN STREET STATION
References to the original construction of Green Street are scarce.
However, there have been few major changes made to the exterior since it was
built in 1912.
Its design marks a clear departure from the Longfellow stations.
The east and west elevations were devoted almost totally to large, plate glass
windows. Above these were copper spandrels decorated with an unusual circle-
I appet mot if.
The window-spandrel composition was unified by a copper string-
course and paneled pilasters decorated with the circle-lappet motif.
stringcourse was a clerestory of smaller plate glass windows separated by
recessed pilasters (HD-89).
Most of the station's interior was sheathed in bead
Boston Elevated Railway Company HAER No. MA-14 Page 47
ash, including the ticket office, which featured an ash grille in the ticket
wi ndow and a center fence wi th an ash handrai 1 (HD-87, HD-88).
In 1976, the
interior was completely rebuilt after it was badly damaged by a fire.
FOREST HILLS STATION
More is known about Forest Hills Station, including the name of its designer, Edmund March Wheelwright, an important local architect who also
designed Park Street Station.
Not only was this station widely publicized at
the time of its construction, but it has been vi rtually unaltered since its
erection in 1909.
Built as a terminus, it markedly differed in design and
construction from earlier stations.
Wheelwright intended it to harmonize with
the Arborway, part of the Boston park system designed by Frederick Law Olmsted.
Wheelwright was also clearly influenced by the stations of the Vienna Stadtbahn
designed by Otto Wagner in the 1890's, particularly the Gumpendorfer Strasse,
Josephstadter Strasse, and Alser Strasse stations on the Gurtel1inie. 
A massive structure of elegant proportions, it was constructed of rein-
forced concrete and embellished with copper details.
Trains approached the
station on a reinforced concrete viaduct which carried a double-track line
High concrete balustrades minimized noise.
Support i ng the
viaduct was a single row of massive steel posts encased in concrete and sup-
ported on foundations 11'6" square and 12' deep.
The ma in frami ng was of deck
construction with steel plate cross and longitudinal girders.
All t i mbe r wo rk ,
including ties, guard rails and feeder box, was of hard pine.
Boston Elevated Railway Company HAER No. MA-14 Page 48
The exterior of the station consisted of two concrete pavilions joined by a
long, double pl atform which was supported on a massive arcade of reinforced
(HP-113, HP-114) concrete piers.
Spanning the arches were two tiers of large,
double-hung glass and wood windows, the upper tier adjusted in shape to the cur-
vature of the arch.
The north pavilion was supported on two concrete posts and
a massive central pier.
Trains entered an arched portal, which was framed by
copper pil asters and keystone.
Recessed copper pilasters, panels, and crenela-
tions embellished the cornice (HD-93 through HD-96).
Inside the pavilion were
wait i ng rooms.
The track was open to the sky; the platforms on either side were
covered by copper canopies supported on posts, braces and diaphragm arches.
south pavilion was similar to the north pavilion except for its roof, which was
hipped instead of flat. 
Despite its scale and material, the overall effect
is light and graceful.
The station is admi rably adapted, not only to its site
but to the elevated system as a whole (HD-97, HD-98, HD-99).

Orange Line Structural Analysis and Description of the Elevated Structure
Section F-l thru F-7
The Orange Line south elevated structure rises from the South
Portal of the Washington Street Tunnel, and then runs along
Washington Street to its terminus at Forest Hills.
majority of the elevated structure consists of one of three variants of a "regular elevated railway deck type" 
structural bay constructed of sections built up of riveted
assemblages of rolled structural steel.
The rolled sub-
components are all standard sections with the exception of
the channels used as column flanges.
These were "speci ally
rolled ... with rounded corners, thus allowing abundance of wheel room and nothing to catch the hubs." 
Generally the structural action of these bays is as follows.
Tracks carry the train loads through their supporting ties,
to the longitudinal trusses or girders.
members frame into the top girders of transverse bents.
transverse girders frame into two columns, supported by
concrete foundations, resting on solid rock, compacted earth
or pile clusters, depending on subsoil conditions. 
Boston Elevated Railway Company HAER No. MA-14 Page 51
The longitudinal members occur in pairs, generally under the
two tracks, and the members of the pair are braced together
laterally by a system of transverse and/or diagonal members
in the horizontal plane.
They are fu rther stabi 1 i zed by a
system of "sway frames" cons i st i ng of crossed members runni ng
from the top chord of one truss or gi rder to the bottom chord
of its mate.
The longitudinal system is supported by an
expans i on pocket at the end of every thi rd span. Between these points rigid connections were used. Late r analysis revealed this to be one of the few des i gn faults in the
The designers considered the longitudinal system to
act as a seri es of s impl e spans, but the ri gi d connections
made them approximate three span continuous beams.

There are three principal variations upon the "standard" bay
The first consists of both longitudinal and
transverse girders constructed from plate girders.
second consists of transverse girder bents and longitudinal
The third consists of longitudinal trusses sup-
ported by "arched truss-bents ("type F")".
These three carry
the bulk of the elevated system.
There are many very mi nor
variations along the right-of-way to accomodate local con-
ditions and more substantial variations at a few special

reasons for use which are principally a function of street
Variations in the supporting structure occur to support the
additional functions required at stations and in response to
special structural requi rements.
Examples of the latter
include the special bent transverse girders composed of

For purposes of discussing specifics of the structure, the
right-of-way has been divided into a series of segments
starting in the north and proceeding southward; these are
defined by the section:

Oescription by Segments
South Portal to Tower 0 (Bents #1215-#1200)
The initial segment of the elevated system, after it emerges
from the Washington Street Tunnel, and up to the point where it crosses the current location of the Massachusetts
Turnpike (formerly the B&A R.R.) does not run co1inear1y with
a street on grade.
It does, however, cross some minor

In addition, the
spans are short in this segment and the longitudinal members
are framed with girders.

MA-14-28 Dudley Station was the original terminus of the system. The HP-41
line terminated in a loop of fairly tight radius, necessi-
tating considerable additional lateral bracing and support.
Around the tight curve, non-prismatic transverse girders were
employed to create the necessary banking.
Even so, thi s
curve was the scene of a major derailment in 1910, shown in
photographs HP-59 and HP-60.
In addition, platform and station
supports, as well as support for the elevated surface line
loops complicate the appearance of the structure here.
In the areas of the station where "a minimum elevation of the
tracks was desired, with the standard head-room below for
street cars and where it was necessary to prevent drippings,

a more util itarian aspect than did the original portion north

In addition to solid web plate girder
transverse bents, longitudinal members are now structured as
sol id web members.
Knee braces have been redesigned with a
single hole, giving the whole structure a heavier appearance.
In certain areas, Washington Street dips markedly, and extra
high bents were designed to maintain the rail grade.

misalignment is not so great as in the northern portion.
Individual girders are adjusted to accomodate the varying
load position. usually by varying the size and location of flange cover plates and web stiffeners, but occasionally by
means of cantilevered outriggers.
Standard track support framing is employed at Egleston
Station, with the exception of one span where upset girders,
with floor beams and stringers, were used to gain headroom
over the passenger access ways.
This section of Washington Street from Egleston Station to
Green Street Station becomes very regular. and the track sup-
port structure is also very regular.
Typical bays occur
throughout the section, modified only by the occasional arch-
chord longitudinal gi rders as described above.
Green Street station was added to the system in 1912 after
the main design was complete.
As a result, the principal
MA-14-64 track support structure is unchanged through the station.

(6) Green Street to Forest Hill Terminal
Proceeding South from Green Street, the typical framing con-
tinues until the Arborway is approached.
This is the final
terminal on the system and its design varies greatly from the
rest of the 1 ine.
The support structure is steel encased in
concrete, with single pylon-like columns carrying both longitudinal supports by means of a "Tee" shaped double can-
ti levered head.
Each pylon actually contains a cluster of
four steel columns, laced transversely.
support is encased in concrete with a long arched soffit
spanning the center line between the columns.
Within the station, two-span transverse bents support longi-

encased in the concrete outer structure of the station.

girders and upset through-type girders.
