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 and Z), as well as the Franklin Avenue and Rockaway Park Shuttles. These lines and services were operated by the Brooklyn–Manhattan Transit Corporation and city-owned Independent Subway System before the 1940 city takeover of the BMT. B Division rolling stock is wider, longer, and heavier than those of the A Division, measuring Script error: No such module "convert". by Script error: No such module "convert"..[2]

The two former systems are still sometimes referred to as the BMT Division and IND Division.[3]

Time period details


Early history

The oldest line to become part of the B Division was the BMT Lexington Avenue Line, opened in 1885. A large system of elevated railways in Brooklyn was formed by 1908 by the Brooklyn Rapid Transit Company (BRT), crossing the Brooklyn Bridge and Williamsburg Bridge to Manhattan terminals. With the Dual Contracts, signed in 1913, the BRT acquired extensions outward into Queens, as well as through Lower and Midtown Manhattan. The BRT became the Brooklyn–Manhattan Transit Corporation in 1923 after a bankruptcy.

The Independent Subway System (IND) was created by the city in the 1920s and 1930s as a third system operated by the city, competing with the BMT and Interborough Rapid Transit Company (IRT). The city took over operations of the BMT and IRT in 1940, consolidating ownership of the three systems into one. Since the original IRT tunnels were smaller, it has remained a separate division to this day.

IND before 1967

IND services were labeled on maps and signs starting with the opening of the first line in 1932. Six letters - A to F - were assigned to the major services, sorted by the north terminal and midtown line, and express services had single letters, while local services had double letters. G and H were assigned to lesser services, which did not enter Manhattan. The following labels were used from 1940 to 1967:

Name North end/type
A Eighth Avenue Express (all times) Washington Heights
AA Eighth Avenue Local (non-rush hours) Washington Heights
BB Sixth Avenue Local (weekday rush hours) Washington Heights
CC Eighth Avenue Local (weekday rush hours) Concourse
D Sixth Avenue-Houston Street Express (all times) Concourse
E Eighth Avenue Express (all times; to Rockaway weekday rush hours starting in 1956) Queens-Jamaica
F Sixth Avenue Express (all times) Queens-Jamaica
GG Crosstown Local (all times) Brooklyn-Queens
HH Fulton Street Local (discontinued in 1946) N/A
HH Rockaway Local (non-rush hours; began in 1956) N/A

Consolidation of operations

Until 1954 and 1955, when the Culver Ramp and 60th Street Tunnel Connection opened, the BMT and IND trackage was not connected. The early joint services using these connections operated similarly to trackage rights; it was not until the Chrystie Street Connection opened in 1967 that the ex-BMT and IND systems were consolidated operationally.

Beginning in 1924,[citation needed] BMT services were designated by number. The city assigned letters (J and up) - generally following the IND pattern of double letters for local services - in the early 1960s to prepare for the 1967 Chrystie Street Connection. Only Southern Division routes (1-4 or N-T) were labeled on maps, but all services except remnants of the old els were assigned letters:[4][5]
