sets of four. History 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. 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. 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 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. Another problem occurred on November 11, 1986, when a train of R68s failed to climb the grade on the Manhattan Bridge. 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. 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). Extensive work performed by the New York City Transit Authority provided solutions to the fleet's many problems. The MTA was given a second option order of an additional 200 subway cars from Westinghouse-Amrail. However, due to
