[5] On August 1, 1920, a tunnel under Flatbush Avenue opened, connecting the Brighton Line to the Broadway subway in Manhattan.

It is installed on the walls of the Coney Island-bound platform's staircase and consists ceramic tiling and glass mosaic depicting various species of birds and rabbits.

[13] Just west of the station, at Locust Avenue and East 14th Street, is the former location of American Vitagraph, a prolific movie studio that produced silent movies from the turn of the 20th century until 1925, when it was purchased by Warner Bros. A smokestack bearing "Vitagraph Co." can still be seen from the station.
