The R12 was a New York City Subway car built in 1948 by the American Car and Foundry Company. The R12 was the first post-war city-owned rolling stock for the IRT division. These cars were very similar to the R10s, except that the R12 was smaller due to A Division specifications. In addition, while the R10s had air-operated door engines (and were the last cars ordered as such), the R12s had electric door engines.

They began service on the IRT Flushing Line (7 <7> services) route in Queens and Manhattan on July 14, 1948, and ran there until 1964 with the delivery of the blue R36 World's Fair cars. The R12 cars were then transferred to operate on other IRT division routes originating in Manhattan, the Bronx, or Brooklyn throughout their service lives. One particular assignment included all fifty of the GE cars (5753-5802) being heavily modified to ease up on the shaking of the old elevated structure, by killing the dynamic brakes and cutting out the third (parallel) notch on their controllers, and sent to the (8) Third Avenue elevated line in the Bronx during August 1969 and ran there until that route's closing on April 29, 1973. In addition, four Westinghouse R12 cars (5703-5706) were slightly modified for use on the Bowling Green – South Ferry Shuttle, and were so-equipped so that the center door of each car could be opened at South Ferry, while keeping the others closed. These cars were used until the shuttle was discontinued in 1977, and were unmodified and reassigned to the 3 train afterwards.

The R12 had a few paint schemes: originally two-tone gray with orange stripes, then a solid bright red, and finally, in the MTA's silver with blue stripe scheme. The last R12 was removed from service in September 1981 and the fleet became work and other non-revenue cars afterward.
