Trench work beneath the tracks of the Ninth Avenue El at West 23rd Street; undated photo.

Completed in 1873, the 23rd Station was originally the penultimate stop for uptown service on the Ninth Avenue El. The station included two side platforms for local trains, and was bypassed by express service via single central track, added in 1916. The station closed and was permanently dismantled in 1940.

In the background, the signature facade piers and front gardens of the original London Terrace complex are visible. The unified full-block development of Greek Revival townhouses stood until 1929, when they were replaced with the high rise apartment complex of the same name.
