The New York City Subway's B Division consists of the lines that operate with lettered services (A, B, C, D, E, F, G, J, L, M, N, Q, R, W, and Z), as well as the Franklin Avenue and Rockaway Park Shuttles. These lines and services were operated by the Brooklyn–Manhattan Transit Corporation (BMT) and city-owned Independent Subway System (IND) before the 1940 city takeover of the BMT. B Division rolling stock is wider, longer, and heavier than those of the A Division, measuring 10 or 9.75 ft (3,048 or 2,972 mm) by 60 or 75 ft (18.29 or 22.86 m).[2]

The B Division is broken down into two subdivisions, B1 (BMT) and B2 (IND), for chaining purposes. The two former systems are still sometimes referred to as the BMT Division and IND Division.[3]
