96th Street is an express station on the IRT Broadway – Seventh Avenue Line of the New York City Subway. Located at the intersection of 96th Street and Broadway on the Upper West Side of Manhattan, it is served by the 1, 2 and 3 trains at all times. 96th Street station was part of the original IRT subway and opened on the inaugural date of October 27, 1904.〔 At the time, the station served as the terminus of local trains and express service; express trains would run as locals north to 145th Street.〔(Some subway ifs and don'ts ) ''New York Times'' (on NYCSubway) Retrieved 2008-09-01〕 ==Station layout== Currently, 96th Street operates in the same manner as other normal express stations in the subway system.〔(96th Street ) ''NYCSubway'' Retrieved 2008-09-01〕 There are two island platforms that allow for cross-platform interchanges between local (outer tracks) and express (inner tracks) trains heading in the same direction, in this case uptown or downtown.〔 During normal service, southbound local trains use track B1 and southbound express trains use track B2. Northbound express trains use track B3 and northbound local trains use track B4. These track designations are not posted in the station, but are used in the chaining of each individual track, used to measure distance by train crews on the subway.〔(New York City Subway chaining ) ''TheJoeKorner'' Retrieved 2008-09-01〕 North of 96th Street, the express tracks descend and turn east under West 104th Street and running northeast under Central Park on their way to the IRT Lenox Avenue Line at West 110th Street. The local tracks remain on the upper level to Riverdale, Bronx. After the express tracks diverge, a currently unused center track starts at approximately 100th Street. Some last minute design changes added the third track northbound, and a provision for a third track was also built into the lower level Lenox branch of the junction. This accounts for the extra space seen alongside the active tracks in this area. The station was extended and widened in 1950 to accommodate longer trains. The extent of the original station is clearly visible, as the renovation was not done in the same style. Differences in the walls and ceiling are visible at the south end. The creation of a new entrance at 94th Street led to the closure of the 91st Street station, as it would have been pointless to lengthen it for 10-car local trains with an adjacent station only a few blocks away.〔 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「96th Street (IRT Broadway – Seventh Avenue Line)」の詳細全文を読む スポンサード リンク
