The New York City and Staten Island Subway systems operates a total of 27 rail yards combined. There are 10 active A Division yards (two yards has been demolished), 14 active B Division yards, two shared yards, two yards for the Staten Island Rapid Transit, and one non-revenue yards. Of these yards, rolling stock are assigned to seven A Division yards, eight B Division yards, and all Staten Island Yards.

A Division Yards

The A Division's yards consist of the 240th Street, 239th Street, Livonia, Jerome, East 180th Street, Pelham and Corona maintenance yards, plus three other non-maintenance storage yards. A total of 3279 cars are assigned to the seven maintenance yards.

137th Street Yard

The 137th Street Yard is an underground rail yard located just north of 137th Street – City College on the IRT Broadway – Seventh Avenue Line, hence the yard's name. It is composed of five tracks surrounding the three mainline tracks. Three tracks are to the west of the line (downtown side) and two are to the east (uptown side). The yard is used to store trains for the 1 train outside of the rush hours.

239th Street Yard

The 239th Street Yard is the northernmost rail yard in the system, located at 4570 Furman Avenue in Wakefield section of the North Bronx, and is home to the R142s and R110s assigned to the 2 and 8 trains respectively. There is considerable fleet interchange with the R142s at East 180th Street Yard used for 5 service. The car wash at 239th Street is used for all services at 239th Street and East 180th Street Yards. 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 2 train were inspected and maintained at the East 180th Street Shops shared with the 5 trains. It re-opened as an inspection and maintenance facility for the 2 train in 1982.

The yard consists of a seven-track inspection shop and 38 layup tracks, able to fit over 100 10 car trains. 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. Access to the 239th Street Yard is located between Wakefield – 241st Street and Nereid Avenue on the IRT White Plains Road Line.

On February 3, 1998, two out-of-service trains collided at the yard lead after the motorman of one train passed out at the helm and his train crashed into the one in front of it.

Cars stored:

  • 500 R110 (8)
  • 410 R142 (2)

240th Street Yard

The 240th Street Yard, also known as Van Cortlandt or VC Yard, is located at 5911 Broadway in the Riverdale section of the Bronx, serving the IRT Broadway – Seventh Avenue Line. The yard consists of six inspection tracks in the shop and 15 additional layup tracks. The yard is home to the R62As and R62s assigned to the 1 and 9 trains. The shop was built in 1906 to support the original IRT subway. The yard and shops are entirely on an elevated structure.

Cars stored:

  • 30 R62 (1/9)
  • 355 R62A (1/9)

Corona Yard

Corona Yard serves the IRT Flushing Line (7 <7> trains). It is located in 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 has seen various models of cars, including Steinway Low-Vs, World's Fair Lo-Vs, BMT Qs, R12s, R14s, R15s, some R17s from 1961 thru early 1965 to enable operation of 11 car trains, and were often mixed with R15s. Some R26s, R28s, R29s were temporarily assigned from 1978 to 1985 due to its assigned fleet of World's Fair R33s, and World's Fair R36s being air conditioned (the World's Fair R33s did not receive air conditioning), and overhauled. A new fleet of World's Fair R33s, and World's Fair R36s in 1963 and 1964. Also R33s from 1989 to 1996 and 2002 to 2003 to temporarily fill in due to light overhaul work on all WFR36 cars done between 1990 and 1996, and also as a fill in due to retirements of many Westinghouse equipped WFR36's during 2002 and 2003. This yard maintains the R39s and R188s used on the 7 <7> services. It also contains the Casey Stengel Bus Depot. Corona Yard does not have room to store all of the new R188s that will exclusively serve the 7 <7> trains by 2016, and expansion of the yard is not viable because the yard is near the Flushing River; therefore, some trainsets will also have to be stored south of the 34th Street station of the 7 <7> services.

On August 16, 2006, the original 1928 shop building was demolished, and was replaced by a new, modern shop.

Cars stored:

  • 506 R188 (7)

Lenox Yard

Lenox Yard, formerly the Lenox Avenue Shops, is located near 148th Street and Lenox Avenue in Harlem, New York. It currently has no maintenance facility and is only used as storage of the R62s that operate on the 3 service. It was the first overhaul shop for the IRT and opened with the 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. Formerly extending between 147th and 150th Streets, in 1960 the yard was downsized from 26 acres to seven acres, which eliminated the repair shops and NYCT offices. Two tracks were taken from the yard for the Harlem – 148th Street station opened in 1968, which is the northern terminal for the 3 train.

Livonia Yard

The Livonia Yard is in East New York, Brooklyn on an entirely elevated structure at the east end of the IRT New Lots Line. One of the smallest maintenance yards in the system, it is where the R62s on the 3 train are inspected and maintained.

The yard consists of four inspection tracks inside the Livonia shop and thirteen layup tracks. Many 3 trains are stored in the Lenox Yard in Upper Manhattan, as Livonia is not very large. Additionally, a large amount of space within Livonia is used for the storage of R142 and R188 cars assigned to the 2, 4 and 5 trains during weekdays.

Cars served:

  • 285 R62 (3)
  • 20 R62A (S)

Tremont Yard (demolished)

The Tremont Yard was a yard that housed service to the 3rd Avenue El lines. Located north of Tremont Avenue Station, this yard was demolished in 1955, along with all service south of 149th Street, and all service left was transferred to the 239th Street Yard.

Unionport Yard

Unionport Yard is associated with the nearby East 180th Street Yard, used primarily as a lay-up facility for the 2 and 5 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. All but one track ends in bumper block. The newly expanded yard was fully operational in 1997. The yard connects to the IRT White Plains Road Line to the south and the IRT Dyre Avenue Line to the north.

It has 45 layup tracks and it holds the R62As and R188s for the 6 train, as well as the twenty R62As used for the 42nd Street Shuttle, and 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.

Cars stored:

  • 429 R62A (6)
  • 20 R188 (6)

B Division

The B Division's maintenance yards comprise the 36-38th Street, 207th Street, Bay Ridge, Concourse, Coney Island, East New York, Jamaica and Pitkin maintenance yards, plus six other non-maintenance storage yards. The seven maintenance shops are responsible for performing daily subway car maintenance and inspection of 3,988 subway cars.

The 207th Street and Concourse yards are shared with the A Division and are listed in Yards in both divisions.

36th-38th Street Yard

The 36th–38th Street Yard, sometimes referred to as the 38th Street Yard, is located between Fifth and Seventh Avenues in Sunset Park, Brooklyn, adjacent to the Jackie Gleason Bus Depot and the Ninth Avenue station of the BMT West End Line, the latter which also stores trains for the yard via the lower level. Green-Wood Cemetery lies to the north of the yard. This yard is mainly used to store R111s for the U, as well as a few revenue-service trains for the B and D. Between 1975 and 2016, the yard was used to store diesel and electrically powered maintenance-of-way and other non-revenue service rolling stock. It is also used to transfer trash from garbage collector trains to trucks via platforms inside the yard just south of 37th Street. There is a control tower for the West End Line at the south end of the yard. The yard is entirely equipped with hand-operated switches. Only Fresh Pond Yard and East New York Yard share this characteristic.

Begining in the 1980's, the Metropolitan Transportation Authority began to enlarge, and modernize this yard to accommodate, inspect and maintain additional revenue service trains here, due to chronic overcrowding at their other existing main facilities, as there was a need to store Second Avenue trains and Coney Island was too far to handle service as many trains would have to run light from Coney Island to Lower Manhattan. The expansion was completed by fall 2016.

This southern part of the yard used to be the center of the South Brooklyn Railway (owned by the Brooklyn Rapid Transit Company), which extended from Bush Terminal through the north part of the yard, then down Gravesend Avenue and into the Coney Island Yard. What is now the Jackie Gleason Bus Depot was formerly the site of a train inspection shed.

125th Street Yard

The 125th Street Yard, also known as the Harlem Yard is an underground yard located just outside the 125th Street station. It is used to store train both from the T and Q lines. There are 3 tracks on the west side and 4 tracks on the east side, totaling 7 tracks (not including the two active tracks used for the 125th Street station), and each yard track can fit at least one full length train. Connections to the yard are located both north and south of 125th Street.

174th Street Yard

The 174th Street Yard is an underground rail yard on the IND Eighth Avenue Line, used to store trains for C service. It is composed of five tracks to the east of the two mainline passenger service tracks. The yard is located six blocks north of 168th Street and adjacent to 175th Street. The inner tracks at 168th Street lead towards the yard and are used by terminating C trains. This yard can hold only three ten-car 60' trains and two six-car 60' trains despite having five tracks; it doesn't affect C service, however. The northern end of the yard is against a concrete wall and a cinder-block wall adjacent to the Trans-Manhattan Expressway, as the line was originally intended to go over the George Washington Bridge's lower level.

Bay Ridge Yard

The Bay Ridge Yard is a Yard located on 6501-6525 2nd Avenue, north of the Bay Ridge Neighborhood. This yard was proposed in the 1980's, and opened in 1987 to both relieve overcrowding in some yards and to expand service on the Second Avenue line. This yard houses the R46s that run on the R line, and connects to the BMT 4th Avenue Line south of 59th Street.

Canarsie Yard

The Canarsie Yard (also known as AY Yard from its telegraphy letters) is located on the south end of the BMT Canarsie Line adjacent to Canarsie – Rockaway Parkway. It is the primary layup yard for the L train and hosts the only car wash for the entire BMT Eastern Division, washing trains for J, L, M and Z services.

New signals were installed in 2003 in conjunction with the BMT Canarsie Line automation project.

Church Avenue Yard

The Church Avenue Yard is an underground rail yard on the IND Culver Line, used to store trains for G service. It is composed of four tracks directly under the four main line tracks above. This yard is directly connected through the IND Church Avenue station which is the south terminus for G service. At least one of the yard's inner-most 4-tracks is in continuous use to turn-back equipment to the opposite direction. There are two ramps between each local and express track south of Church Avenue station for access. Each track can hold one full-length train between the bumper blocks and the crossovers.

Coney Island Complex

The Coney Island Complex is the largest rapid transit yard in the state of New York. Located in Brooklyn, New York, it covers 75 acres (300,000 m2) and operates 24/7.

The complex was built in 1926 on former marshlands that, along with Coney Island Creek, used to separate Coney Island from the main body of Brooklyn. Much of this land had originally been proposed for use as a ship canal and port facility.

Regular scheduled maintenance is performed here for a fleet of nearly 800 cars of R68s, R68As, and R160s, serving the B, G, N, Q, and the Franklin Avenue Shuttle. However, train sets for the D and F lines are also stored here when required. The shop facility along with 207th St. does heavy maintenance and overhaul for every one of the approximately 6,000 cars in the subway system.

In addition to heavy maintenance facilities and track facilities for cars undergoing maintenance and overhaul, the complex includes three related railroad storage yards. The main yard facility, known as Coney Island Yard, includes direct connections to the adjacent BMT Sea Beach Line (N train) and a two-track elevated structure to the BMT West End Line (D train). The main yard also serves trains on the BMT Brighton Line (B Q trains) via tracks C & D (aka 3 & 4) of Coney Island – Stillwell Avenue station. The adjacent but separate Culver Yard (also called City Yard or Avenue X Yard) connects to the IND Culver Line (F train) at the eastern border of the yard complex. Another yard, the Stillwell Yard, used mainly for off-peak train storage, is located across the Sea Beach Line from the main yard complex in a "V" between the divergent Sea Beach and West End Lines.

In addition to the maintenance shop and yards, there is a Health Center (gym) for Transit Authority employees and a firing range for the New York City Police Department (NYPD). The range was originally built for the New York City Transit Police Department, which was merged with the NYPD in 1995.

The Coney Island Yard Electric Motor Repair Shop and Coney Island Yard Gatehouse were listed on the National Register of Historic Places in 2006.

East New York Yard

East New York Yard (also known as DO (District Office) Yard from its telegraphy letters) is primarily used to store and repair trains assigned to the J, L, M and Z. Subway equipment is inspected and maintained there on a regular basis.

It is located at the junction of the Canarsie and Jamaica Lines near the intersection of Broadway and Jamaica Avenue in East New York, Brooklyn. A separate part of the facility houses the East New York Bus Depot, formerly a trolley depot. The yard is entirely equipped with hand-operated switches. Only the Fresh Pond Yard and 36th–38th Street Yard share this characteristic.

Portions of the yard date back to 1885 and the Lexington Avenue Elevated and the yard predates the rebuilding of nearby Broadway Junction, which used to be known as Manhattan Junction or East New York Loop.

The yard and its main lead configuration remained the same before and after the extensive elevated line rebuilding nearby, but additional track and structure was built, so that, at its peak, East New York Yard had direct connections to the Broadway Elevated going west, Jamaica Line going east, Canarsie Line going east, and Fulton Street Elevated both east and west.

Jamaica Yard

Jamaica Yard is located in Kew Gardens, Queens at the south end of Flushing Meadows–Corona Park near the Kew Gardens Interchange. It is the primary storage yard for the IND Queens Boulevard Line since its opening in 1936. The yard connects to the Queens Boulevard Line at a three-way flying junction just geographically north of the Kew Gardens – Union Turnpike station. The yard is at surface level, and the four-track approach includes a bridge over the Grand Central Parkway; though the Queens Boulevard Line is underground, the yard lies at a lower elevation than the subway. The site upon which the yard sits at the head of the valley of the Flushing River was, during the American Revolution, occupied by British troops after the Battle of Long Island.

The yard was built for the Independent Subway System in the 1930s. Work was half finished on Jamaica Yard in April 1935, and the total cost of Jamaica Yard and storage sheds cost about $560,000. Jamaica Yard served as the south end of the World's Fair Railroad which served the 1939 New York World's Fair from 1939 to 1940. In August 1964 it was planned that Jamaica Yard have car-washing machines installed in May 1965. The yard currently provides carwash, interior cleaning, grease and minor repair services to the R46s and R160s that are assigned to the E, F, and Y lines. Some R160As and R46s for the M and R respectively are stored here as well during weekdays. The M's cars are not allowed to be maintained here, as the M uses shorter, four-car sets maintained at East New York Yard.

Staten Island Rapid Transit

Arlington Yard

Arlington Yard is a Staten Island Railway yard located west of the Arlington station, east of Western Avenue, and north of the Staten Island Expressway in the Port Ivory neighborhood. The yard leads into the Travis Branch of the railway, the Howland Hook Container Terminal, and the Arthur Kill Lift Bridge to Elizabeth, New Jersey and the Chemical Coast and is part of the ExpressRail network. The yard opened in 1886, and was the first stop for freight trains coming from New Jersey. Arlington Yard is also the hub of Staten Island's railway system, and houses all the maintenance in the system. The Yard stores R55s and R83s for their respective lines. Before 1980, this yard was the main yard for the Red line.

The engine house at Arlington was a small, two stall, cinder-block building. There was a tank car to fuel locomotives in the yard. Materials used to perform minor repairs to freight cars could be found inside the building.

Clifton Yard

The Clifton Yard is a Staten Island Railway yard located next to the Clifton station. Heavy maintenance of the equipment is performed at the Clifton Yard. The R44 subway cars on the the Blue and red lines are maintained here, although major work is done at the Arlington Yard as there is some maintenance that Clifton Yard cannot perform. Additional storage for revenue trains is located adjacent to the Tottenville station at the south end of the blue line, while maintenance of non-revenue trains is performed at a Maintenance of Way shop near the Tompkinsville station.

Travis Yard

The Travis Yard is a satellite yard that is used to store any trains that cannot be stored in the Arlington or Clifton Yards. It mostly stores R44s for the Red line, but may also store some R55s and R83s whenever necessary. This yard's location is just after the red line's portal to Staten Island Mall.

Other Yards

Linden Shops

Linden Shops is a track shop, where track switches and other components are assembled. It has track connections to the IRT New Lots Line and BMT Canarsie Line, but no third rail, restricting the facility to diesel-powered trains only. There is also a track connection to the Long Island Rail Road's Bay Ridge Branch. This connection is one of two from the subway to the mainline United States rail network (the BMT West End Line is the other).
