The cars were built in France from 1986 to 1988 and shipped through New York Harbor. Of the cars in the fleet, 416 are arranged in four-car sets while the other nine are single cars.
The R68 was the third R-type contract to be built with 75-foot (22.86 m) cars (the previous two being the R44 and R46). The first R68 train entered service on June 20, 1986. The R68's manufacturers suffered from significant system integration problems, and the fleet became known as a "lemon" in its early years, but its performance was improved following modifications by the New York City Transit Authority. In the 2010s, a small number of R68s received experimental upgrades.
Description[edit]
The interior side route & destination rollsign on the WExterior fixed side signage dedicated to the Franklin Avenue ShuttleThe front route rollsign on the QThe R68 was the third R-type contract to be built with 75-foot (22.86 m) cars (the previous two being the R44 and R46), which have more room for sitting and standing passengers per car than the 60-foot (18.29 m) cars that were used previously and afterward. Like the R44s and R46s, which are also 75 feet (22.86 m) long, they are prohibited from running on the BMT Eastern Division lines (J, L, M & Z trains) because of tight curves. This order was evolved from the R55,[5] a proposed car that was considered in the early 1980s, but never left the drawing board, or purchased due to a lack of funding. Instead, more attention was paid to replacing the R12, R14, R15, and R17 fleets of the A Division, which were over 30 years old and worn-out at the time.
The cars, numbered 2500–2924, cost about $1 million each. They replaced many R10s dating from 1948, all remaining 6300-series R16s dating from 1954 to 1955, and some R27s and R30s dating from 1960 to 1962. The cars are built with stainless steel, and are graffiti-resistant.[6]
The R68s are currently based in the Concourse Yard in the Bronx (cars 2500–2775) and the Coney Island Complex in Brooklyn (cars 2776–2924). The Concourse sets are currently assigned to the D, while most Coney Island sets are currently assigned to the B, N, Q, and W, and cars 2916–2924 are assigned to the Franklin Avenue Shuttle. As built, the R68s were originally single units, with a full-width cab on one end and a half-width cab on the other end. The R68s on the shuttle remain as single units with OPTO switches added, while the rest of the fleet were reconfigured into sets of four.
History[edit]
On October 15, 1982, the Metropolitan Transportation Authority announced that it would purchase 225 cars from Westinghouse-Amrail. The cars were built in France from 1986 to 1988 and shipped through New York Harbor. The first of the 225 cars were initially scheduled to arrive in January 1985, with the entire order complete in May 1986. The projected cost of the order was $210 million, or about $933,000 per car.[6]
The delivery of the first R68 was made on February 4, 1986, but it failed to pass a sharp curve on the South Brooklyn Railway trackage on 38th Street in Brooklyn, and as a result, the curve had to be rebuilt and the radius eased somewhat, and the delivery took place on February 26, 1986. The 30-day acceptance test for the R68s began on the Brighton Line on April 13, 1986. The R68s' first entry to revenue service was on June 20, 1986, on the Brooklyn half of the divided D train with the first fleet consisting of cars 2500–2507.[7] There were two contracts to supply the R68 fleet. The primary order consisted of cars 2500–2724, while the option order consisted of cars 2725–2924. The R68, therefore, became the first subway fleet to have an option order.
Initial problems[edit]
The R68's manufacturers suffered from significant system integration problems. Poor communication and coordination between the car body builder (ANF Industrie) and the chassis assembler (Westinghouse) led to operational failures. Due to this, the R68s became known as a "lemon". During the beginning of service, the R68s had problems with malfunctioning doors, faulty wiring, electrical controls that suddenly lost power, and malfunctioning air brakes. In addition, the fleet had a high breakdown rate.[8] Another problem occurred on November 11, 1986, when a train of R68s failed to climb the grade on the Manhattan Bridge.[9] The fleet had a Mean Distance Between Failure of 12,368 miles by the end of 1986—slightly above the system's average, but far less than the MDBF figures for the R62 and R62A fleets.[10] By April 1987, the MTA's manager of car equipment engineering estimated that 20 percent of the R68 fleet had faulty controllers (which controlled braking and acceleration).[11] Extensive work performed by the New York City Transit Authority provided solutions to the fleet's many problems.[9]
The MTA was given a second option order of an additional 200 subway cars from Westinghouse-Amrail. However, due to problems from the manufacturer, the MTA awarded it to Kawasaki.[9] Westinghouse-Amrail offered to have the 200 cars built for $1,012,000 each, while Kawasaki agreed to have them built for $958,000 per car. This order became the R68A.[8]
Replacement and equipment tests[edit]
The R68s are scheduled to remain in service until at least 2025–2030.[12] In 2010, the MTA proposed mid-life technological upgrades for the R68s, including LED destination signs and automated announcements.[13][14]
LED lights were tested on cars 2860–2867. LED lights, door chimes (similar to those on the R142, R142A, and R179), and PA systems were tested on 2892–2895. Public Address and Intercom, LED displays, LCD displays, and CCTV, as well as Train Operator displays, were tested on cars 2844 and 2846. Display screens were tested on cars 2804–2807. LED lights and surveillance cameras were tested on 2792–2795. Each program gave out the date and time, and all retrofitted cars ran on the G.[15] However, none of the displays indicated the next stops along the routes.[16] All upgrades were later removed, and no further upgrades were implemented until early 2021, when car 2860 received a newer LED signage and CCTV system from Suzhou Huaqi Intelligent Technology. The entire consist was pulled from service on April 22, 2021, due to concerns over Suzhou Huaqi's ties to the Chinese government.[17] It is unlikely that further technological improvements will be implemented in the near future.[13]
In June 2023, the MTA released a document advertising an RFP for the R262 and R268 models, the latter of which is likely to replace the R68 and R68A.[18]

The R68A was the fourth and final R-type contract to be built with 75-foot (22.86 m) cars (the previous three being the R44, R46, and R68). The contract had been given to Kawasaki because the manufacturers of the base R68 order, the joint venture Westinghouse-Amrail Company, had experienced significant integration issues that led to performance problems with the R68s. The first R68A train entered service on May 18, 1988. The R68As are scheduled to remain in service until at least 2025–2030.
Description
The R68As are numbered 5001–5200. They were the last cars to be built with a length of 75 feet (22.86 m) (the previous three being the R44, R46, and R68). While the 75-foot (22.86 m) length allows more room for sitting and standing passengers per car than the 60-foot (18.29 m) length that was previously used, these cars suffer from clearance issues and cannot run on the BMT Eastern Division. Additionally, the reduced number of doors on a train of eight 75-foot (22.86 m) cars have led to increased boarding and dwelling times. As a result, subsequent B Division subway car orders have returned to the previous length of 60 feet (18.29 m), the first being the R143 order in 2001.
The R68As are currently based out of the Coney Island Yard and are assigned to the B, N, and W, and occasionally run on the Q. In addition, one set runs on the A train during weekday afternoon rush hours, which occasionally uses an R68. Like the previous R68 order, the R68As were originally single units, with a full-width cab on one end and a half-width cab on the other end. They were eventually linked into four-car sets and continue to run in this configuration.
History
Delivery and revenue service
Side destination and route rollsigns of an R68AThe first R68A cars were delivered to New York on April 12, 1988, and transferred to TA facilities the following day.[6] The cars replaced all of the remaining R10s, R27s, and unrebuilt R30s, all of which were retired between 1989 and 1993. The R68As were built with American and Japanese parts.
The R68As' first entry to revenue service was on May 18, 1988, on the Bronx and Manhattan half of the divided D train with the first fleet consisting of the consist 5010-5001-5006-5008-5009-5007-5004-5005.[6] Originally, the R68A order was supposed to be a second option order of the R68. However, due to poor performance from the R68 cars produced by Westinghouse-Amrail, along with other issues, the MTA gave the order to Kawasaki, with an offer of $958,000 per car versus Westinghouse-Amrail's offer of $1,012,200 per car.[5][7]
Replacement
The R68As are scheduled to remain in service until at least 2025–30.[8] In 2010, the MTA proposed mid-life technological upgrades for the R68As, including LED destination signs and automated announcements.[9][10] These upgrades were not implemented.
In June 2023, the MTA released a document advertising an RFP for the R262 and R268 models, the latter of which is likely to replace the R68 and R68A.[11]
