In making the plans for this section (Section H) the Commission deemed it desirable to locate the subway in the BOSTON TRANSIT COMMISSION . center of Dorchest er avenue in order to avoid rebuilding a r n r n la ge i te cepti g sewer at considerable expense . This loca tion brought one of the sidewalls of the subway directly under the surface tracks of the Boston Elevated Railway Company an n r f d i c eased the di ficult y and cost of construction . An arrangem ent was made between the contractor and the Com pany by which the Company agreed to relocate its tracks r n ns r n r n n an for du i g the co t uctio of that po tio of the sect io , d such purpose the Commission granted a temporary location on .

A contract was executed with the Company for the use of that

was n r 14 1 15 . ope ed to public use Ap il , 9 It is hoped that the tunnel can be opened for public travel as f ar as the South Station in about six months .

E nlargement ofP ark S treet S tation .

In connection with the construction of the Dorchester tun e] the Commission was authorized to enlarge the Park street

A description of the interior finish of the Washingt on station is as follows : The ceilings and upper part of the walls of

n r the station including the lobby are of white ceme t plaste . The lower part of the walls are of white polished terrazzo with a border of white and red ceramic tile and red terrazzo at the top between the white terrazzo and the plaster and also at the bottom between the white terrazzo and the granolithic

r rr base . A border of red and white ce amic tile is also ca ied

r n n n n r r u n in a ou d the advertisi g pa els . The i te io col m s the lobby are encased with concrete having a granolithic finish those on the platform level of the station are finished with

rr rr n te azzo and ceramic tile to co espo d with the walls . See P 1 late .

At a n -fil n n r or this st tio two double e i cli ed elevato s, escala r one for r n to s , of the cleat typ e , each platfo m , have bee

ns a r n r i t lled and tested . These escalators ca ry the passe ge s r r r r f om the platfo m level to the level of the su face of the st eet . The escalator from the platform for eastbound trains has a 3 0 BOSTON TRANSIT COMMISSION . vertical lift of about 34 feet and lands the passengers at the Chaunc r a and it in r r y st eet sidew lk level, adjacent to , p ope ty r r taken for the pu pose . The escalator from the platfo m for westbound trains has a vertical lift of about 35 feet 34 inches and lands the passengers at the Hawley street sidewalk

n i in r r f r a d n t r . level , adjace t to , p ope ty taken o the pu pose The reason for taking private property for the location of these escalators was because of the narrow and congested

r in n sidewalks and st eets the vici ity . E scalator T ests: Besides various electrical and temperature tests of the electric motors the escalators were subjected to an ffi ienc n r m u r haunc e c y test u de the maxi m cont act load . The C y street escalator was subjected to a full load test by carrying passengers at the rate of p er hour at 140 pounds p er p as n f r r r se ger or th ee consecutive hou s . This escalato is located near one of the stairways of the station and the m en em ployed in the test could ride up on the escalator and readily walk down the stairs to ride up again and repeat this trip c on l r n m t inuous y du i g the test . With 336 en it w as possible to keep the escalator continuously loaded with approxim ately

rr r its full sp ecified load . The total load ca ied du ing the test

r m n n for r rs was at the ate of e at pou ds th ee hou ,

r or pounds p er hour . This exceeded the cont act r r n In m u r equi eme t by about p er cent . the maxi m hou the r rr r men or n s escalato ca ied at the ate of , pou d , which exceeds the contract requirement by about p er t 2 cent . In he maximum 0 minutes it carried at the rate of

m en or n r r n co pou ds p e hou , exceedi g the n r r n r n tract equi eme t by about p e ce t . D r n r n r n r u i g this test , eadi gs we e obtai ed f om which the efficiency of the escalator at the contract load was determined

2 r n . n r r n to be 7 p e ce t , which exceeds the co t act gua a tee. by

r ffi i nc n r r 10 p e cent . The e c e y is co side ed as the atio between the horsepower used in lifting the m en and the horsepower received over the feed wires at the control apparatus . As the Hawley street escalator is not located near a stair ’ r a r r way , it was imp actic l to make a th ee hou s full load test by a r on h n r r method simila to the e used at C au cy st eet . The moto In field was tested under its maximum rated load . the the escalator was tested under a light load for a period of eight

The East Boston Tunnel Ext ension is built of reinforced

It begins at a point in the original East Boston Tunnel abo ut 90 feet west from the westerly line of Washington street and n n r C r r r n r exte ds u de ou t st eet , Scollay squa e, Bowdoi squa e , Green and Cambridge streets and comes to the surface by an incline in the middle of Cambridge street between Chambers r r A st eet and No th Russell street . t this place Cambridge street has been widened about 46 feet to provide a roadway on n n P each side of the i cli e . See late 9 . At the beginning of the East Boston Tunnel Ext ension near W n r h r nn r ashingt o st eet , t e g ade of the old tu el was lowe ed , the Court street station abandoned and a new station built in Scollay square below the old station of the Tremont Street

During the year the work on Section G has comprised the general construction of the Scollay Under station and the con r n nn n st uctio of the tu el to the east of the station . The statio has been completed with the exception of some of the terrazzo finish on the walls and white cement plaster finish on the upper

Structu es on the surface covering the stairway exit and the escalator exit in the middle of Court street in front of the Crawford House and a structure over the entrance stairway on Hanover r n r st eet are yet to be co structed . The pa t of Section G west of the station was substantially completed at the date of the

r r last annual report . Easterly f om the station the wo k has involved the lowering of the grade of the East Boston Tunnel between Cornhill and the westerly end of the Ames Building . This has required the removal of the old invert and very c onsiderable portions of the old tunnel walls and the building

n r n n w r of a ew inve t a d e walls , togethe with the use of heavy steel girders to support the roof and portions of the walls of the

r n old structure that were not removed . Such po tio s of the work as could be built while maintaining the use of the Court n street station for t raffic were built first . This i cluded some of the column foundations and the setting of the steel girders n r at the westerly end of the old Court street statio . The wo k entailed the removal of a large amount of concrete masonry and the careful supporting of the old structure . It became n n r 15 necessary to discontinue the use of this statio o Novembe ,
