A Division (New York City Subway)

The A Division, also known as the IRT Division,[2] is a division of the New York City Subway, consisting of the lines operated with services designated by numbers (1, 2, 3, 4, 5, 6, 7) and the 42nd Street Shuttle.[3] These lines and services were operated by the Interborough Rapid Transit Company before the 1940 city takeover. A Division cars are narrower, shorter, and lighter than those of the B Division, measuring 8.6 by 51 feet (2.62 by 15.54 m).[4][5]
