The R68 is a B Division New York City Subway car order consisting of 425 cars built by the Westinghouse-Amrail Company (aka Francorail), a joint venture of Westinghouse, ANF Industrie, Jeumont Schneider, and Alsthom. 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 series consisting of 75-foot (22.86 m) cars. 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.
