DeKalb Avenue station

DeKalb Avenue is a local station shared by the BMT Fourth Avenue Line and the BMT Brighton Line of the New York City Subway, located at the intersection of DeKalb and Flatbush Avenues in Brooklyn. It is served by the Q and R trains at all times, the B train on weekdays, and the D and N trains during late nights. During rush hours only, a few W train trips in the peak direction also serve this station.

This station opened on June 22, 1915, and was completed on August 1, 1920. Since it opened, DeKalb Avenue has been referred to as "the heart of the BMT", as it is a major transfer point between BMT services with lines splitting north and south of the station. Platform extensions were built into a curve south of the station in 1927 to allow for longer trains. They were closed and replaced by straight extensions to the north in 1960. The abandoned portions can be seen from the open platforms and trains.
