The R68A is a B Division New York City Subway car order consisting of 200 cars built between 1988 and 1989 by Kawasaki Railcar Company in Kobe, Japan, with final assembly done at the Kawasaki plant in Yonkers, New York.[5] A total of 200 cars were built, arranged in four-car sets.
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.
