[2][6] The connection to the BMT was severed on April 26, 1956, and the IND was extended east (railroad south) from Euclid Avenue via a connecting tunnel and new intermediate station at Grant Avenue, with the new service beginning on April 29, 1956.

[2] A 1924 system map portrayed the station as "Greenwood Avenue" with "111th St." below it in parentheses and smaller print.

[16][17] The A train stops here at all times except nights, running to Brooklyn and Manhattan; a shuttle train from Euclid Avenue to Ozone Park–Lefferts Boulevard serves the station during late nights.

[12] Both platforms have beige windscreens for the entire length and brown canopies with green frames and support columns except for a small section at either ends.

The other station house also has one staircase to each platform, waiting area, and two staircases to 109th Street and Liberty Avenue (one to the southeast corner and another along the north side of Liberty Avenue).
