than its current terminus at East 180th Street on the IRT White Plains Road Line. Improvements On June 6, 1946, the New York City Board of Transportation announced that a contract for the installation of signal equipment that would allow express service to run on the Pelham Line was jointly awarded to the Emerson–Garden Electric Company and L. K. Comstock & Company Incorporated for $129,516. The signals were to be installed between Third Avenue–138th Street and Parkchester. Beginning October 14, 1946, weekday rush and Saturday morning rush peak direction express service started, with Pelham Bay trains using the middle track between East 177th Street and Third Avenue–138th Street. This express service saved eight minutes between Third Avenue and East 177th Street. During this time, 6 trains that ran local in the Bronx when express trains operated began to terminate at East 177 Street to make room for express trains to Pelham Bay Park. Express service did not start until this date because of the increase in ridership from the huge Parkchester housing complex at East 177th Street. On November 8, 1947, Union Switch and Signal Company was awarded a contract for $819,375 for block signaling on the Pelham Line. This would have allowed an extension of express service from Parkchester to Pelham Bay Park. The Westchester Yard was expanded between 1946 and 1949 and the scope of the project included a new signal tower, signal installations, and the elimination of the grade crossings between the yard and the Pelham Line north of the Westchester Square station. All of these projects would allow for quicker main line service and train movements in and out of the yard. The grade separation allowed trains to enter Westchester Yard without crossing the express track or the downtown local track and it allowed for the possibility of the extension of express service to Pelham Bay Park, which would save four more minutes. The increased capacity of the yard allowed for storage of 358 additional subway cars. With the additional space, it would no longer be required to lay up trains on the middle track of the line between East 177th Street and Pelham Bay Park, and it would allow for full day express service. The construction of substations would improve voltage conditions and allow for longer trains to be operated on the line. The work was projected to cost $6,387,000 and it was projected to
