The R7 was a New York City Subway car built in 1937 for the city-operated Independent Subway System by two manufacturers under separate orders, the American Car and Foundry Company and Pullman Standard.
On March 5, 1937, the New York City Board of Transportation opened up bids for 150 cars to be built under the R7 contract–a continuation of the R6 fleet. The winning bid for $40,375 per car was jointly submitted by the American Car and Foundry Company (ACF) and Pullman Standard. The Pressed Steel Company also submitted a bid, for $40,850 per car. On July 27, 1937, it was announced that the winning bid for 100 additional cars, under contract R7A, went to ACF and Pullman for $41,951 per car. Additional bids were made by Pressed Steel ($42,200) and Bethlehem Steel ($43,100). The increased in price per car was attributed to strikes in the steel industry. Together, these two orders provided additional cars for expanded service in Queens and for the opening of the IND Crosstown Line. The R7As were built in 1938.
The R7s and R7As were used exclusively for service on the IND (later IND Division) until 1968–1969, when they were displaced by the new R40 and R42 cars, and were transferred to the East New York Yard of the BMT Eastern Division. They were used on the former BMT J, KK, LL, M, and QJ routes until 1977, when the R7s and R7As were retired, and replaced by the R46s.
R7A car 1575 has been preserved by the New York Transit Museum. It was restored to operating condition and has been used in excursions sponsored by the Transit Museum since June 8, 2003. 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, the first series of post-war city-owned subway cars built from 1948 to 1949. It was designed to test new interior and cosmetic features that would later be incorporated into the R10 fleet. While it cosmetically resembles an R10, mechanically and electrically it is still an R7A and can only operate with other prewar IND Arnines.
