The IND Culver Line is a rapid transit line of the B Division of the New York City Subway, extending from Downtown Brooklyn south to Coney Island, Brooklyn, New York City, United States. From its beginning at an interlocking north of Jay Street – MetroTech, where Culver Line trains can access the IND Sixth Avenue Line or IND Eighth Avenue Line, south to Church Avenue in Kensington, the line is mostly a four-track subway, though it rises to cross over the Gowanus Canal on the only above-ground structure on the original Independent Subway System. In Kensington, a ramp allows the line to rise onto a three-track elevated structure built by the City for operation by the Brooklyn Rapid Transit Company as part of the Dual Contracts. When this ramp was opened in 1954, the older route from Kensington northwest to Sunset Park remained as the Culver Shuttle until it was closed in 1975. The final portion of the line in Coney Island is on the lower level of a double-decked elevated structure, with the BMT Brighton Line above. The local tracks of the Culver Line are served by the F service, as well as the G between Bergen Street and Church Avenue. The express tracks north of Church Avenue have not been regularly used since 1976, while the peak-direction express track between Ditmas Avenue and Avenue X has not seen regular service since 1987.〔 The elevated part of the Culver Line, operated as part of the BMT division until 1954, now carries only the F, a former IND service, and is chained〔(【引用サイトリンク】title=New York City Subway CHAINING )〕 and signaled〔City of New York Office of the Comptroller, (Dilemma in the : Capital Needs of the World's Capital City ), August 1998, signal system data table (page 197) from the New York City Transit Authority〕 as part of the IND. However, BMT radio frequency B1 is used on the elevated portion of the line south of Church Avenue.〔 ==Extent and service== The Culver Line is served by the as a local for its entire length. The portion of the route from Bergen Street south to Church Avenue is also served by the Brooklyn–Queens Crosstown service. Both routes run at all times. There are two express tracks on the northern part of the route and one on the southern, with express stations distributed along the line. However, there has been no no express service on the Culver Line since 1987. Express service has only operated once on the line from 1968 to 1987. Restoration of express service has been thwarted by budget shortages, passenger opposition, and a serious signal fire at Bergen Street in 1999.〔〔 The issue came to a head in June 2007, when a petition for express service reached 2,600 signatures and gained media attention.〔 The Culver Line underwent repairs from 2009 until early 2013, during which the express tracks were replaced and rehabilitated which may facilitate future express service.〔〔〔(Another delay mars Smith-9th rehab project ).〕 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「IND Culver Line」の詳細全文を読む スポンサード リンク
