to service cars assigned to the and routes. Westchester Yard The Westchester Yard, also known as the Pelham Yard, is located in the Bronx and has 45 layup tracks. The yard maintains and stores the R62As used on the , as well as Maintenance of Way diesel trains for both the A Division and B Division. It is connected to the IRT Pelham Line in both directions between Westchester Square–East Tremont Avenue and Middletown Road stations. There is a four-track inspection shed for electric trains and a two-track diesel repair shop. Pelham Yard also has a car wash used by the entire A Division. 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 sped up 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 the yard to store 358 additional subway cars. With the additional storage 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 be completed in 1950. B Division yards The B Division's yards are the 207th Street, Concourse, Coney Island, East New York, Jamaica and Pitkin maintenance yards, plus five other non-maintenance storage yards. The six maintenance shops are responsible for performing daily subway car maintenance and inspection of 3,523 subway cars. The 207th Street and Concourse yards are shared with the A Division and are listed in Yards in both divisions. 174th Street Yard The 174th Street Yard is an underground rail yard on the IND Eighth Avenue Line that is used to store trains. The yard has five tracks to the east of the two mainline passenger service tracks. The yard
