The R7A was a New York City Subway car order consisting of 100 cars that were built in 1938 by two separate orders from different manufacturers; the American Car & Foundry (#1600-1649), and Pullman Standard (#1550-1599). Most if not all of these cars were transferred to the BMT Eastern Division in 1968 and 1969 and served there until 1976 and 1977 when the R7As retired.

Preservation[edit]

Car 1575 has been preserved by the New York Transit Museum and restored. During its service life, it was rebuilt from its original appearance by ACF in 1947 after an accident, and became the prototype for the R10. It was designed to test new interior and cosmetic features. While it cosmetically resembles an R10, mechanically and electrically it is still an R7A and can only operate with other prewar IND Arnines.
