Nostrand Avenue is a Fulton Street line express stop with a most unusual station layout. Just before and after the station the tracks stack on top of one another with the express tracks on the upper level and the local tacks below. Another Interesting feature is that the express platforms are extremely wide because the express tracks exits at the position where they would be (if the stop was a local stop on one level) right in the middle of the station. The local platforms are much more narrow since their tracks are a floor below but to the side of the express tracks, with simply the wider express platform over them. The local platforms each even have their own track walls, so the lower level is completely split with no views to the opposite direction.
The station's trim is a yellow center with a much darker yellow boarder, it covers all of the platform walls as well as the track walls on the local lower-level split tracks, below the trim everywhere it exists is the standard Nostrand tiling, this could perhaps give Nostrand Avenue the record for the number of times the station's name is tiled since it's tiled on four platform walls pulls the two side walls of the local tracks. There are name tablets that say Nostrand Av along all four station platforms, these have white text on a dark yellow background with a light yellow border.
There are staircases at regular intervals connecting the two platform levels with each other, but no free crossovers or under between to allow different directional transfer. Each direction has a single exit that is accessed from fare control directly on the Express platforms towards their eastern ends with staircases up to Fulton Street at either side of Nostrand Avenue. There is evidence from unpainted out exiting tiling beneath some of the name tablets of a now closed exit at the western end of the station to Bedford Avenue. On the sidewalk are large, metal Do Not Block grates with the M MTA logo where the streetstairs used to be.
The Bedford Avenue exit reopened opened on February 4, 2021 and based on the layout of the entrance and long walk from entrance to the platforms, it is understandable why it was closed around 1990 during concerns about crime. The entrance reopening also restored a free crossover, change of direction transfer at this station, although it is quite a walk to make this transfer. This reopened entrance consists of streetstairs (with normal green streetstairs added where the do not block grates were) at the NE and SE corners of Bedford Avenue and Fulton Street. These lead down to a full-width mezzanine and fare control. After the turnstiles, this mezzanine has a full-width area of a decent distance, before two passageways lead from the eastern end of the full-length mezzanine and become separate ramps down to the western ends of each express platform. It is quite a long walk from entrance to station platform.
