Ninth Avenue station

Ninth Avenue is a bi-level express station on the BMT West End Line of the New York City Subway, located at the intersection of Ninth Avenue and 39th Street in Brooklyn. Each level has three tracks and two island platforms. The upper level serves the BMT West End Line while the lower level formerly served the BMT Culver Line. Only the upper level is still in service and is served by the D train at all times. The center express track is not normally used.

The upper level is the only one in use. Only the local tracks are in regular service. On the upper level, the Manhattan-bound platform is slightly wider than the Coney Island-bound platform. Towards the west end of the upper level platforms is an employee-only pedestrian bridge that leads to the entrance of the 36th–38th Street Yard via a high turnstile. A control tower for line at the south end of the yard.
