This underground station has two tracks and one island platform. It is the northernmost Brooklyn station for the A and C trains. To the north, the IND Eighth Avenue Line enters the Cranberry Street Tunnel and passes under the East River into Manhattan. As a result, the station was built in a tube design, and built with escalators between the upper fare control level and the lower mezzanine level to easier traverse the 70 foot (21 m) drop below street level.
