The BMT Standard cars were built by the American Car and Foundry Company and Pressed Steel Car Company between 1914 and 1924. They were operated by the BRT and its successor, the BMT until 1940. In that year, the BMT was purchased by the City of New York and operation of the fleet was transferred to the New York City Transit Authority. The Standard cars were made of steel and designed to operate in subway tunnels. Prior to this, the BRT only operated elevated lines, so it was able to use wooden cars on its lines. These cars were the first New York City Subway cars to have rollsigns, running lights on the front of the train, and after an upgrade, a single conductor could operate all the train's doors from an interior cab position. Many Standards were overhauled between 1959 and 1962, and the fleet was retired gradually during the 1960s. Five cars have been preserved.
