The R15 was a New York City Subway car built in 1950 by the American Car and Foundry Company. These cars were somewhat similar to the R12/R14 cars and they were the first to feature round (turtle-back) roofs, porthole door windows, and conductors door operating apparatus controls located inside the motorman's cabs, instead of on the outsides as on the R12/R14s. They began service on the 7 (IRT Flushing Line) service in Queens and Manhattan on February 4, 1950, running there until 1964 with the delivery of R33 WF/R36 WF cars. While they ran in solid consists on the Flushing line, the R15s were always intermixed with later cars once they were transferred to the mainlines.
Eventually, the R15 cars were transferred to operate on other IRT division routes originating in Manhattan, the Bronx and/or Brooklyn throughout their service lives, starting in 1964, and ran there until their retirement on December 10, 1984 when the R15s were replaced by the R62/R62A fleet.
Car 6239 had been previously and fully restored in 1976 and survives today as part of the displayed collection at the New York Transit Museum in Brooklyn. It has operated on fantrips since 2004, and is the sole surviving R15 unit in existence.
