The
A Division's yards consist of the 239th Street, 240th Street, Corona, East 180th Street, Jerome, Livonia, and Westchester maintenance yards, plus three other non-maintenance storage yards. A total of 2892 cars are assigned to the seven maintenance yards. Cars in the A Division may be loaned to other yards if necessary maintenance prevents access.
137th Street Yard The
137th Street Yard is an underground
rail yard located between
145th Street and
137th Street–City College on the
IRT Broadway–Seventh Avenue Line, the latter of which is the yard's namesake. The yard is used to store some trains outside of rush hours. Each track can hold two full-length trains, so a total of 10 trains can be stored there at any given time. Because the tracks are on a 1% downgrade in the southbound direction, each of the layup tracks are equipped with a derail to protect the main line from a runaway train in the event a train placed on any one the storage tracks is not properly secured.

Opened in 1916, it is one of the oldest yards in the system. Ten cars are inspected each day as part of preventative scheduled maintenance. A wheel truing machine was installed here to minimize damage to rail cars and tracks caused by flat wheels. This shop was also used as a facility to retrofit all R26s, R28s, R29s, R33s (except single unit Worlds Fair cars) and R36s (both Mainline and Worlds Fair types) married pairs IRT type cars with the installation of new Stone-Safety 10 ton Air Conditioning systems between 1976 and 1981. Also, during this period, all cars assigned to the were inspected and maintained at the East 180th Street Yard shared with the . It re-opened as an inspection and maintenance facility for the in 1982. A car wash operates at this yard facility to serve cars assigned to the 2, in addition to cars assigned to the , , and 5 routes. The yard consists of a seven-track inspection shop and 38 layup tracks. The layup tracks are arranged on two levels; the only other yard in the system to share this trait is the East New York Yard.

The inspection shed went into service on May 1, 1911. The yard and shops are entirely on an elevated structure. There is no car washer at this yard; trains usually go to be washed at the nearby 207th Street Yard and occasionally to the 239th Street or Westchester Yard. Ten cars undergo 10,000 mile SMS inspections per day, since their entire fleet has been unitized into five-car sets. As part of the 2020–2024 Capital Plan, the shop will be rebuilt with more space in between track and the replacement of pits with elevated tracks.
Corona Yard Corona Yard serves as the home yard of the
IRT Flushing Line (). It is located south of
Mets–Willets Point, at
Flushing Meadows–Corona Park near
Citi Field, the
National Tennis Center, and the site of the
1939 and
1964 World's Fairs. Corona Yard opened in 1928 and maintains the
R188s used on the . It is adjacent to the
Casey Stengel Bus Depot. Because the Flushing Line is isolated from the rest of the A Division and its only track connection to the rest of the system is via the B Division, cars that need to undergo or are returning from heavy maintenance are escorted on and off the line by suitably-equipped lead cars via the sole connection to the rest of the system just east (railroad north) of the upper level
Queensboro Plaza station. On August 16, 2006, the original 1928 shop building was demolished and replaced by a new, modern shop. With more track mileage to cover and tighter spacing between trains as part of CBTC implementation on the Flushing Line, the MTA announced plans to expand the yard with a second loop and six layup tracks, which would be located on the former right of way of the Long Island Rail Road's Whitestone Branch. Plans for this expansion are on an indefinite hold, however.

East 180th Street Yard is situated at 1145 East 180th Street in the
West Farms neighborhood of
the Bronx, just east of the
Bronx Zoo. The yard consists of seven storage tracks (numbered 4 thru 10) and an adjacent 6-track (numbered 11 thru 16) shop building with a connection to the nearby 19-track Unionport Yard, which lies to the northeast of East 180th Street Yard.

Track A ends in a bumper block and track B is accessible from the southbound track of the White Plains Road line. The yard is the home of the
R142s for the . There is considerable fleet interchange with the . All engineering acceptance testing for newly delivered IRT-type cars is performed here. A new shop building replacing the original 1918 vintage shop building opened in 1999, just in time for acceptance testing of new R142s, which Bombardier started delivering to this facility on November 16, 1999. On October 11, 1923, additional tracks in the yard went into service.
Jerome Yard The
Jerome Yard, or Mosholu Yard, is located at 3191 Jerome Avenue in the

R62s that operate on the , and has no maintenance facility, although the yard had been the first overhaul shop for the
IRT when it opened with the rest of the
new subway in 1904. The original IRT subway cars were lowered from the street via inclines into the yard, where they continued into the
West Side Main Line. The inspection shed was lengthened to fit ten-car trains in Fiscal Year 1910. Formerly extending between 147th and 150th Streets, in the 1960s the yard was downsized from 26 acres to seven acres, which eliminated the repair shops and NYCT offices. The land was sold to a developer. Around that time, a public school building (currently housing
Frederick Douglass Academy) and the Esplanade Gardens apartment complex were constructed on
pilotis above the formerly open-air yard.
Livonia Yard The
Livonia Yard is located at 900 Hegeman Avenue in
East New York, Brooklyn on an entirely elevated structure at the east end of the
IRT New Lots Line. Located between Elton and Linwood Streets, the yard extends from Hegeman Avenue south to Stanley Avenue, passing over
Linden Boulevard. One of the smallest maintenance yards in the system, it is where the
R62s on the and the

42nd Street Shuttle are inspected and maintained. Additionally, a large amount of space within Livonia is used for the storage of some
R142s and
R142As for the , and trains.

East 180th Street Yard, and is used primarily as a lay-up facility for and trains. It is named after Unionport Road, which lies just east of the yard. There are no shop or wash facilities at this yard, which was expanded in the 1990s from five tracks to its present 19 (numbered 19 to 37). All but one track ends at bumper blocks. The newly expanded yard became fully operational in 1997. The yard connects to the
IRT White Plains Road Line to the south and the
IRT Dyre Avenue Line (track 22 connecting to track Y2) to the north. In addition to serving
Manhattan Elevated Railway cars, it was also used 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. Pelham Yard also has a car wash used by the entire A Division. 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 ==
