the station actually at 20th Avenue and 86th Street
New York City Subway station in Brooklyn

The 20th Avenue station is a local station on the BMT Sea Beach Line of the New York City Subway, located on 20th Avenue between 63rd and 64th Streets in the Mapleton neighborhood of Brooklyn. It is served by the N train at all times. During rush hours, several W trains also serve this station.

This station opened on June 22, 1915. The Coney Island bound platform was closed from July 31, 2017 to July 1, 2019.

This open cut station has four tracks and two side platforms, but the two center express tracks are not normally used. The Coney Island bound express track has been disconnected from the line and the Manhattan bound track is signaled for trains in both directions. Both platforms are carved within the Earth's crust and made of concrete. They have beige walls and columns (the columns having previously painted blue green), and the station signs are the standard black plates in white lettering. There are also some old lights that are out of use, and 1960s era benches. The 2019 artwork here is called Sea City Spin by David Storey. It features abstract glass mosaics based on Storey's experience of riding the BMT Sea Beach Line.

This station has one entrance/exit towards the east (railroad south) end. Two staircases from each platform go up to an enclosed concrete crossover before a set of doors lead to the waiting area of the stucco and tile station house. Outside the turnstile bank, there is a token booth and a set of doors leading to the east side of the 20th Avenue overpass/tunnel above the platforms and tracks.
