The New York City Subway is a large rapid transit system and has a large fleet of rolling stock.

Total fleet

As of December 2015, the New York City Subway has 6,407 cars on the roster.^{[2][lower-alpha 1]} The system maintains two separate fleets of cars: one for the IRT routes, the other for the BMT/IND routes. All BMT/IND equipment is about 10 feet (3.05 m) wide and either 60 feet 6 inches (18.44 m) or 75 feet 6 inches (23.01 m) long whereas IRT equipment is approximately 8 feet 9 inches (2.67 m) wide and 51 feet (15.54 m) long. The A Division and B Division trains operate only in their own division; operating in the other division is not allowed because the IRT sections have narrower tunnel segments, tighter curves, and tighter platform clearances than the BMT/IND sections. IRT Division trains would have an unacceptably large gap between the platform and train if they were allowed in the BMT/IND Division, and BMT/IND trains would not fit in the IRT tunnels and stations. The safety train stop (trip cock) mechanism between divisions is also incompatible, being located on opposite sides of the track and train in each division. Service and maintenance trains are composed of IRT sized cars, do not carry passengers, and can operate on either division as the safety train stop is built on both sides of the trucks. However, all rolling stock, in either A or B Division, runs on the same 4 ft 8.5 in (1.44 m) gauge.

There is also a special fleet of BMT/IND cars, used for operation in the BMT Eastern Division, which is the J, L, M and Z trains. The BMT Eastern Division has sharper curves and shorter platforms, so these trains can only use eight 60-foot (18.29 m) long cars. As of June 2013, R32 and R42 married pairs along with R143 and R160A four-car sets are assigned to the BMT Eastern Division. 75-foot (22.86 m) long cars, like the R44s, R46s, R68s, and R68As are not permitted on BMT Eastern Division trackage.

A typical revenue train consists of 8 to 11 cars, although shuttles can be as short as two, and the 7 runs 11-car trains. Train lengths range from about 150 to 600 feet (46 to 183 m) long. As a general rule, trains on A Division lines inherited from the IRT (designated with numbers, plus the 42nd Street Shuttle) are shorter and narrower than those that operate on B Division lines inherited from BMT/IND (designated with letters).

When the Brooklyn Rapid Transit Company entered into agreements to operate some of the new subway lines, they decided to design a new type of car, 10 feet (3.05 m) wide and 67 feet (20.42 m) long. The subject of several patents, the car's larger profile was similar to that of steam railroad coaches, permitting greater passenger capacity, more comfortable seating, and other advantages. The BRT unveiled its design, designated BMT Standard, to the public in 1913 and received such wide acceptance that all future subway lines, whether built for the BRT, the IRT or eventually, the IND, were built to handle the wider cars.

When the R44s and R46s were rebuilt, the rollsigns on the side of the cars were replaced with electronic LCD signs while the front service sign remained as a rollsign. In sharp contrast, the rebuilt R32s and R38s retained rollsigns on the sides, but an LCD display was placed in the front. The MTA has been incorporating newer subway cars into its stock in the past decade. Since 1999, the R142s, R142As, R143s, R160As, and R160Bs have been added into service.^[3][4] All cars built since 1992, (including the now out-of-service R110As and R110Bs) are equipped with digital signs on the front, sides, and interior (except for the R110B, which has rollsigns on the front).

Old cars, some from the original companies (IRT and BMT), are preserved at the New York Transit Museum, while others have been sold to private individuals, rail and trolley museums. Between 1984 and 1989 some of the IRT trains were painted red, giving them the name Redbirds.^{[lower-alpha 2]} Since then, all of these cars have been replaced by more modern subway trains (R142/R142As) between 2000 and 2005. As of September 2010, older BMT/IND cars (most R32s, all R38s, all R40s, all R40As, almost all R42s, and almost all R44s) have been retired and replaced with the R160s.

General Overhaul Program

The General Overhaul Program (GOH) was a mid-life overhaul program for neglected subway cars which involved thorough rebuilding of the fleet. Since the completion of the GOH program, the new Scheduled Maintenance System (SMS) program has replaced the GOH program by ensuring that trains do not reach a state in which they would need such an overhaul. The car types which were part of the MTA NYCT GOH program are the IRT Redbirds (R26, R28, R29, R33, R33 WF, R36, R36 WF), as well as IND/BMT cars (R30 GE, R32, R38, R40, R40A, R40M, R42, R44 and R46). These cars were rebuilt between 1985 and 1992. Some cars in various classes from R10 to R46 were also given lighter overhauls during this period.

"R"-prefixed orders

Cars purchased by the City of New York since the inception of the IND and for the other divisions beginning in 1948 are identified by the letter "R" followed by a number; e.g.: R32. This number is the contract number under which the cars were purchased. Cars with nearby contract numbers (e.g.: R1 through R9, or R21 through R36 WF, or R143 through R160B) may be virtually identical, simply being purchased under different contracts.

The New York City Board of Transportation settled on a system of documentation that is still in place under MTA New York City Transit. This included a prefix letter or letters that indicated the Department that the specific documentation, followed by a series of numbers of a length defined by the specific department concerned. For example, the Surface Department used the letter "S", while the Rapid Transit Department used the letter "R". A new R- number is assigned for any vehicle purchase involving a bidding process. Since the 1970s, the system has suffered from "R- inflation" going through only 46 R- numbers in its first 40 years, but over 114 in its subsequent 30. Possible reasons include an increased number of specialized maintenance vehicles that were previously made in house or a lower floor for requiring a formal bidding process in order to reduce waste and abuse.

Disposal at sea

Retired subway cars being transported to the ocean, where they will be dropped into the water to create an artificial reef

In 2001 the New York City Transit Authority started disposing of retired subway cars by dumping them at sea to create artificial reefs, which are intended to promote marine life. This option was chosen because it was less expensive than removing asbestos from the cars. The asbestos was determined to not be a hazard in the ocean.^[5] Further, the artificial reefs would provide environmental and economic benefits, such as providing shelter for marine animals and creating new fishing opportunities. The first reef constructed was Redbird Reef in Delaware. Eventually, multiple states received retired subway cars for reefs.^[6] The program was discontinued in 2010, after more than 2,500 cars were reefed because newer cars contained more plastic, which was too expensive to economically remove before reefing.^[7][8]

Track geometry car

The track geometry car at Jay Street – Borough Hall.

The two-car track geometry car set of the New York City Subway helps to measure the system's track geometry. It measures:

• Alignment - "Alignment is the projection of the track geometry of each rail or the track center line onto the horizontal plane," (FRA Definition).^[16] Also known as the "straightness" of the tracks.
• Crosslevel - The variation in cant of the track over the length of a predetermined "chord" length (generally 62 feet or 18.90 meters). On straight or tangent track, ideally there should be no variation, while on curves, a cant is generally desired.
• Curvature - The amount by which the rail deviates from being straight or tangent. The geometry car checks the actual curvature (in Degree of curvature) of a curve versus its design curvature.
• Rail gauge - The distance between the rails. Over time, rail may become too wide or too narrow. In North America and most of the world, standard gauge is 4 ft 8 ¹⁄₂ in (1,435 mm).
• Rail profile - Looks for rail wear and deviations from standard profile.
• Warp - The maximum change in crosslevel over a predetermined chord length (generally sixty-two feet).^[17]
• Corrugation of running rail surface
• Tunnel and station platform clearances
• Third rail height and gauge
• Vertical gap between third rail and protective board^[18]

The track geometry car typically checks each stretch of track about 6 times a year; the car is manually operated, and there are no plans to automate inspection of the track geometry, which is done manually with the help of high-tech equipment aboard the car.^[19]

The "Train of Many Colors" makes another appearance on the 7 train in 2008, commemorating the last game at Shea Stadium

• Air conditioning is standard on all cars R42 and later. R38s 4140-49 and R40s 4350–4549 were also delivered with A/C, and all cars not equipped with A/C from classes R26-R40 (With the exception of the R27, R30, and R33WF) were later retrofitted with A/C. All active cars are equipped with air conditioning and cars with malfunctioning air conditioning are not supposed to be put into service.^[25]
• During World War II, a group of old New York elevated line cars dating from the late 19th century was sent west to the San Francisco Bay Area by the United States Maritime Commission for use by the Shipyard Railway, a temporary wartime electric line transporting workers to the Kaiser Shipyards. After the war, most were sold to be used as units in a local motel, but their whereabouts afterwards is unknown. Two of them however were acquired and have been restored by the Western Railway Museum in Rio Vista, California.^[26]
• There are many examples of rolling stock built under contract which are not intended for revenue service, such as the R95 money train, R127/R134 garbage train and R156 work locomotive.^[27]
• The table below shows what year the TA had expected to retire several car models in 1981.^[28]

2. Redbirds are R26, R27, R28, R29, R30, R33, and R36. Many cars are still in use as work trains (Most remaining cars are R33s). Sometimes the term "Redbird" would also be used on the R27 and R30 cars as they were repainted Gunn red during the late 1980s and early 1990s before retirement. These were known as the BMT Redbirds.
3. Most IND/BMT (B Division) cars are 60 feet (18.3 m) long unless noted; all IRT (A Division) cars are 51 feet (15.5 m).
4. The New York City Subway R44s were retired in 2010. The Staten Island Railway R44s are still in service.
