The line began at the company's office at the intersection of Grand Street and Kent Avenue, and proceeded south on Kent Avenue (Brooklyn City Rail Road's Greenpoint Line), east on Broadway (Broadway Railroad's Broadway Line trackage), north on Bedford Avenue, east on South Fourth Street and Meserole Street, and southeast on Bushwick Avenue.
At the end of that line, it turned west on several blocks of new trackage on Driggs Avenue before reaching the Brooklyn Crosstown Railroad's Crosstown Line in Manhattan Avenue.
[2][3] This was built somewhat differently as the Tompkins Avenue Line the next year.
[6] On October 18, 1888, the court ruled that the BCRR had no right to operate over the Brooklyn Crosstown Railroad trackage on Manhattan Avenue, gained through an 1875 agreement between the Bushwick and Crosstown Railroads.
[9] The BCRR leased the Crosstown in mid-1889,[10] but did not restore the Bushwick Avenue branch to the ferry.
