The Brooklyn and North River Line, operated by the Brooklyn and North River Railroad, was a trolley line in Manhattan and Brooklyn, New York City, United States. Its route ran from the Desbrosses Street Ferry across Lower Manhattan via the Canal Street Crosstown Line, over a pair of tracks on the east side of the Manhattan Bridge, and to the intersection of Flatbush Avenue and Fulton Street in Downtown Brooklyn. Operation in Manhattan and over the bridge was with conduit electrification, while in Brooklyn it used overhead trolley wire, switching at a plow pit.
