the new connection commenced, and the BMT Culver Shuttle was instituted between Ditmas Avenue and Ninth Avenue, making Ditmas Avenue an inter-division transfer station. When the BMT Culver Shuttle ceased on May 11, 1975, the station was left to be served by the IND Culver Line only. On March 5, 1944, when the elevated BMT Myrtle Avenue Line was removed from the Brooklyn Bridge elevated tracks, and cut back from Park Row to Bridge–Jay Streets, a paper transfer was added at Bridge–Jay Streets to the Brooklyn Bridge trolley lines, specifically the Smith Street Line, DeKalb Avenue Line, and Seventh Avenue Line. Bridge trolleys were discontinued on March 6, 1950, and the transfer was replaced with one to the IND Sixth Avenue Line.
