The B68 is a bus route that constitutes a public transit line operating in Brooklyn, New York City.

[citation needed] In 1890, in order to compete better with the steam railroads that had been opened to Coney Island beginning in 1864, the CI&B became the first horsecar line in Kings County to electrify, using trolley wire.

[citation needed] The CI&B acquired the Grand Street, Prospect Park and Flatbush Railroad (Franklin Avenue Line) in the early 1890s, and leased the Brooklyn City and Newtown Rail Road (DeKalb Avenue Line) in 1897.

[citation needed] The Coney Island and Gravesend Railway, a Brooklyn Rapid Transit Company subsidiary, bought a majority of CI&B stock in 1913 or 1914;[4] it remained part of the BRT (Brooklyn-Manhattan Transit Corporation after 1923) system until the BMT was purchased by the City of New York in 1940.

[5] In July 2001, service was extended from West 5th Street to the Coney Island subway station.
