The '''IND Culver Line''' (formerly [[IND Culver Line#History|BMT Culver Line]]) is a [[rapid transit]] line of the [[B Division (NYCS)|B Division]] of the [[New York City Subway]], extending from [[Downtown Brooklyn]] south to [[Coney Island]], [[Brooklyn]], New York City, United States. The local tracks of the Culver Line are served by the [[F (New York City Subway service)|F]] service, as well as the [[G (New York City Subway service)|G]] between [[Bergen Street (IND Culver Line)|Bergen Street]] and [[Church Avenue (IND Culver Line)|Church Avenue]]. The express tracks north of Church Avenue are used by the [[Fd (New York City Subway service)|&lt;F&gt;]] train during rush hours in the peak direction. The peak-direction express track between [[Ditmas Avenue (IND Culver Line)|Ditmas Avenue]] and [[Avenue X (IND Culver Line)|Avenue X]] has not seen regular service since 1987.<ref name="MTA-FLineReview-2009" />

The line is named after [[Andrew Culver (railroad)|Andrew Culver]], who built the original [[Culver Line (surface)|Culver Line]] that preceded the current subway line. The present-day line was built as two unconnected segments operated by the [[Independent Subway System]] (IND) and [[Brooklyn–Manhattan Transit Corporation]] (BMT). The northern section of the line, between [[Jay Street–MetroTech (IND Culver Line)|Jay Street–MetroTech]] and Church Avenue, is a four-track line that was built for the IND in 1933, running primarily underground except for a short elevated section over the [[Gowanus Canal]].

The southern section, between [[Ditmas Avenue (IND Culver Line)|Ditmas Avenue]] and [[Coney Island–Stillwell Avenue (New York City Subway)|Coney Island–Stillwell Avenue]], was originally built for the BMT in 1919–1920 as a three-track elevated structure between [[Ninth Avenue (BMT Culver Line)|Ninth Avenue]] in [[Sunset Park, Brooklyn|Sunset Park]] and Avenue X, and as a two-track elevated structure south of Avenue X. A ramp in the neighborhood of [[Kensington, Brooklyn|Kensington]], which opened in 1954, connects the segments between the Church and Ditmas Avenues stations. The segment of the BMT line between Ninth and Ditmas Avenues remained as the [[Culver Shuttle]] until it was closed in 1975 and later demolished.

The elevated part of the Culver Line south of Church Avenue, which operated as part of the BMT until 1954, now carries only the F, a former IND service, and is [[chained (NYCS)|chained]] and [[signal (rail)|signaled]]<ref>[[New York City|City of New York]] Office of the Comptroller, [http://www.comptroller.nyc.gov/bureaus/eng/complete.pdf Dilemma in the {{sic|nolink=yes|Mille|nium}}<!-- PLEASE NOTE that "Millenium" is deliberately spelled incorrectly here, reflecting the mistake on the external page. -->: Capital Needs of the World's Capital City] {{webarchive|url=https://web.archive.org/web/20061001154606/http://www.comptroller.nyc.gov/bureaus/eng/complete.pdf |date=October 1, 2006}}, August 1998, signal system data table (page 197) from the [[New York City Transit Authority]]</ref> as part of the IND.
