The BMT Broadway Line is a rapid transit line of the B Division of the New York City Subway in Manhattan, New York City, United States. , it is served by three services, all colored : the on the express tracks and the on the local tracks. The line is often referred to as the " and ",〔Randy Kennedy, New York Times, (Honoring the Champions ), October 31, 2000, section B, page 10: "And the only reason she was standing in the middle of Broadway was that she was below it. Underground. In the N and R subway station."〕〔Susan Saulny, New York Times, (In Subway Changes, W Follows V, but for Riders It's Not So Simple ), section B, page 1: "The Q, N, R and W trains would all run on N and R tracks in Manhattan."〕 since those were the only services on the line during the long years that the Manhattan Bridge south tracks were closed for rebuilding. The Broadway Line was built to give the Brooklyn Rapid Transit Company (later the Brooklyn–Manhattan Transit Corporation) access to Midtown Manhattan. The line is named for its location under Broadway between Vesey Street and Seventh Avenue (Times Square). It also passes under Vesey Street, Whitehall Street, Trinity Place, and Church Street in Lower Manhattan, and Seventh Avenue, 59th Street, and 60th Street in Midtown. The local tracks stretch the entire length between the two East River tunnels: the Montague Street Tunnel to the BMT Fourth Avenue Line in Brooklyn and the 60th Street Tunnel to the BMT Astoria Line and 60th Street Tunnel Connection in Queens. Center express tracks exist between Canal Street and 57th Street, turning off at Canal Street to feed the south tracks on the Manhattan Bridge, and continuing north and east under Central Park as the BMT 63rd Street Line (presently unused, but planned to connect with the Second Avenue Subway). The Broadway Line was the only Manhattan outlet north of Delancey Street for the BMT's Brooklyn lines until 1967, when most BMT Brighton Line and BMT West End Line trains were moved to the IND Sixth Avenue Line via the new Chrystie Street Connection. ==Extent and service== Services that use the Broadway Line are colored . The BMT Broadway Line begins at the 60th Street Tunnel from Queens. It runs west as a two-track subway line under 60th Street (east of Fifth Avenue) and 59th Street (west of Fifth Avenue), with stations at Lexington Avenue / 59th Street and Fifth Avenue / 59th Street. It then turns south to Seventh Avenue into the local tracks at 57th Street – Seventh Avenue. This segment of the line carries the services from the BMT Astoria Line and the service from the IND Queens Boulevard Line. At the 57th Street station, the line joins two express tracks that enter the station from the north via the BMT 63rd Street Line. There is no scheduled BMT service on the 63rd Street Line at present. The BMT 63rd Street Line will carry the service across 63rd Street and up the proposed Second Avenue Line. The express tracks at 57th Street are currently used as terminal tracks for the train on late nights and weekends. The BMT Broadway Line proceeds as a four-track subway down Seventh Avenue to its intersection with Broadway, and then continues down Broadway to a point north of Canal Street, where the express tracks carrying the services descend and turn sharply east into the Canal Street (formerly Broadway) station of the BMT Broadway – Manhattan Bridge Line. Immediately after Canal Street, the express tracks resume again (originally they had been intended to run through) and serve as storage and turning tracks, bypassing the Canal Street local station and ending in the disused lower level of City Hall. The local tracks continue south as a two-track subway to Whitehall Street – South Ferry station. Whitehall Street – South Ferry is a three track, two-platform station, with the center track set up as a terminal track, formerly used as the south terminal for now defunct service. Now, the center track is currently only used during service disruptions. A pair of bellmouths exists here, allowing for a connection to a never-built East River tunnel south of the Montague Street Tunnel. It has been proposed to use this as part of the Lower Manhattan – Jamaica/JFK Transportation Project, connecting to the Court Street station (New York Transit Museum) in Brooklyn.〔Community Consulting Services, Inc. in association with George Haikalis, Transportation Consultant, , revised April 2003, page 49〕〔Regional Rail Working Group, , page 4 (includes a map)〕 The BMT Broadway Line then curves east carrying the trains to a trailing junction with the BMT Nassau Street Line ( trains) and enters the Montague Street Tunnel to Brooklyn. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BMT Broadway Line」の詳細全文を読む スポンサード リンク
