The BMT Nassau Street Line is a rapid transit line of the B Division of the New York City Subway system in Manhattan. It is a continuation of the BMT Jamaica Line in Brooklyn after crossing the Williamsburg Bridge; it continues to a junction with the BMT Broadway Line just before the Montague Street Tunnel after which the line reenters Brooklyn (no revenue service south of Broad Street since June, 2010).
While the line is officially recognized as the Nassau Street Line, it only serves one station on Nassau Street: Fulton Street.
The M service has historically served the Nassau Street Line. Since June 28, 2010, the M has been rerouted via the Chrystie Street Connection to run on the IND Sixth Avenue Line, as a replacement for the V. The M continues to serve one Nassau Street Line station: the Essex Street station.
The following services use part or all of the Nassau Street Line. The trunk line's bullets are colored terra cotta brown:

After the original IRT opened, the city began planning new lines. Two of these were extensions of that system, to Downtown Brooklyn and Van Cortlandt Park, but the other two - the Centre Street Loop Subway (or Brooklyn Loop Subway) and Fourth Avenue Subway (in Brooklyn) - were separate lines for which construction had not progressed as far. The Centre Street Loop, approved on January 25, 1907 as a four-track line (earlier proposed as two tracks), was to connect the Brooklyn Bridge, Manhattan Bridge, and Williamsburg Bridge via Centre Street, Canal Street, and Delancey Street. An extension south from the Brooklyn Bridge under William Street to Wall Street was also part of the plan, as were several loops towards the Hudson River and a loop connecting the bridges through Brooklyn. Construction contracts for the main line in Manhattan were awarded in early 1907, despite no determination of the operator once completed. The line was assigned to a proposed Tri-borough system in early 1908 and to the Brooklyn Rapid Transit Company (BRT) in the Dual Contracts, adopted on March 4, 1913.
The BRT began operating through a short piece of subway, coming off the Williamsburg Bridge under Delancey Street to Essex Street, on September 16, 1908. The Centre Street Loop was opened to Chambers Street (at the Brooklyn Bridge) on August 4, 1913, with temporary operation at first on the two west tracks. The south tracks on the Manhattan Bridge, also running into Chambers Street, were placed in service on June 22, 1915. An extension south from Chambers Street to the Montague Street Tunnel, known as the Nassau Street Loop, was not completed until May 30, 1931, as part of the Dual Contracts.
Plans for the Chambers Street area changed several times during construction, always including a never-completed connection to the Brooklyn Bridge tracks. By 1910, only the west two tracks were to rise onto the bridge, and the east two were to continue south to the Montague Street Tunnel. As actually built for the 1931 opening south of Chambers Street, the two outer tracks ran south to the tunnel, while the two inner tracks continued several blocks in a lower level stub tunnel to allow trains to reverse direction.
On September 20, 2004, northbound trains began running on the second track from the west (serving the former southbound platform), and the former northbound platforms at Canal Street and Bowery were closed off. The second track from the east was removed.
