The R15 was a New York City Subway car model built by the American Car and Foundry Company in 1950 for the IRT A Division. A total of 100 cars were built, arranged as single units. Two versions were manufactured: Westinghouse (WH)-powered cars and General Electric (GE)-powered cars.
The first R15s entered service on February 4, 1950; the fleet initially ran on the IRT Flushing Line until the R33S and R36 World's Fair fleets were delivered in the 1960s. The R15s were replaced by the R62s in the 1980s, and the final train of R15s ran on December 10, 1984. One R15 car was saved for the New York Transit Museum, and the rest were scrapped.
