The lower level was used as a through route for the BMT Culver Line to the BMT Fourth Avenue subway and the BMT Fifth Avenue elevated lines until 1954, when service on the main portion of the BMT Culver Line route was recaptured by the Independent Subway System via the Culver Ramp. A Culver Shuttle service from this station to a new single track terminal at Ditmas Avenue began at the same time. Some Culver trains continued to operate into Manhattan until May 1959. Culver Shuttle service was discontinued on May 11, 1975. The lower level was abandoned afterwards and has not been used for passenger service.
