The 6 Lexington Avenue/Pelham Local and <6> Lexington Avenue Local/Pelham Express are two rapid transit services in the A Division of the New York City Subway. Their route emblems, or "bullets", are colored since they use the IRT Lexington Avenue Line in Manhattan.〔http://web.mta.info/developers/resources/line_colors.htm〕 Local service is denoted by a (6) in a circular bullet, and express service is denoted by a <6> in a diamond-shaped bullet. 6 trains normally operate local entirely between Pelham Bay Park in the Bronx and Brooklyn Bridge – City Hall in Lower Manhattan. During rush hours and middays in the peak direction, <6> Bronx express trains replace 6 local ones north of Parkchester, and run express between that station and Third Avenue – 138th Street. During this time, 6 Bronx local trains short turn at Parkchester. Weekdays from 9:00 to 11:00 a.m., some Manhattan-bound <6> trains run local from Parkchester to Hunts Point Avenue while some Parkchester-bound 6 trains run express in that section. == History == On October 27, 1904, local and express service opened on the original subway in Manhattan, following the route of the present IRT Lexington Avenue Line from City Hall to Grand Central – 42nd Street. From there, the service traveled west on 42nd Street on the route of the present 42nd Street Shuttle, and then north on the present IRT Broadway – Seventh Avenue Line to 145th Street. The current "H" configuration—with separate services along Lexington Avenue and Broadway – Seventh Avenue—was introduced in 1917.〔(【引用サイトリンク】 title=New Subways For New York: The Dual System of Rapid Transit - Interborough Routes and Stations )〕 Full Lexington Avenue local service from City Hall to 125th Street opened on July 17, 1918. On August 1, 1918, Third Avenue – 138th Street opened with trains running between there and City Hall, making all stops.〔http://www.erictb.info/linehistory.html〕 On January 17, 1919 trains were extended from 138th Street to Hunts Point Avenue,> and on May 30, 1920, 6 service was extended to East 177th Street.〔 On October 24, 1920, 6 service was extended again to Westchester Square.〔 On December 20, 1920, 6 service was extended to Pelham Bay Park.〔 From that point on, the current 6 service was formed. All trains ran local between Pelham Bay Park and Brooklyn Bridge, with some trains terminating at the City Hall loop. By 1934, service south of the City Hall station had been discontinued, and late-night service ran from Pelham Bay Park to 125th Street only. On December 31, 1945, City Hall station closed, and the former Brooklyn Bridge station (renamed Brooklyn Bridge – City Hall) became the permanent southern terminal. 6 trains still used the loop, though, to get from the southbound to the northbound local track at Brooklyn Bridge - City Hall.〔(The Abandoned City Hall Subway Stop Now Visible To Tourists (PHOTOS) )〕 On May 10, 1946, late-night service resumed to Brooklyn Bridge.〔 Beginning October 14, 1946, weekday rush and Saturday morning rush peak direction express service started, with alternate trains using the middle express track between East 177th Street and Third Avenue – 138th Street.〔 From December 15 to 22, 1950, weekday rush trains were extended to South Ferry.〔 On June 23, 1956, Saturday express service was discontinued.〔 Starting April 8, 1960, late night and weekday evening trains were extended to South Ferry, followed by weekend evening service October 17, 1965; however, all trains were again cut back to Brooklyn Bridge by May 23, 1976.〔 Beginning in January 13, 1980, late night service terminated at 125th Street in Manhattan with the running as a local in Manhattan. On the same day, Bronx express service was expanded to weekday middays, with alternate trains running express southbound to noon, then northbound into the PM rush.〔 From March 4 to Summer 1985, there was a 6 train that left 138th Street at 7:20 AM, then turned at Atlantic Avenue, and left at 8:18 AM returning to Pelham Bay Park. This was the only time that the 6 service was scheduled to operate to Brooklyn.〔 In 1990 from January 21 through October 5, late night service was extended back to Brooklyn Bridge, but then was again cut back to 125th Street.〔 On October 3, 1999, late night service was permanently extended to Brooklyn Bridge, but the still runs local.〔 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「6 (New York City Subway service)」の詳細全文を読む スポンサード リンク
