The AB Standard was a New York City Subway car class built by the American Car and Foundry Company and Pressed Steel Car Company between 1914 and 1924. It ran under the operation of the Brooklyn Rapid Transit Company (BRT) and its successors, which included the Brooklyn–Manhattan Transit Corporation (BMT), the New York City Board of Transportation, and the New York City Transit Authority (NYCTA). The cars were designed following the signing of the Dual Contracts, which called for a major expansion of the BRT. A total of 950 cars were built.
In their earliest days of service, operating crews frequently called them Steels to distinguish them from the wooden BU elevated cars. However, these cars were most commonly referred to as BRT Standards, BMT Standards, or simply Standards. Train crews and the car shop departments often referred to them as 67-foot cars, AB-types, or most frequently ABs.[not verified in body] For their time, the cars introduced a significant number of improvements to urban rapid transit. The AB Standards were slowly retired in the 1960s, last running in 1969. Several AB Standards have been preserved.
