Nostrand Avenue is located on the quite unusual stacked Eastern Parkway Subway. In the station, the express tracks stacked above one another on the northside of the line, and the local tracks are on the south side. This means the station's two side platforms are directly on top of one another on different levels, on the southern side of the tracks. The main reason for this unusual arrangement is that just south of the station at the Rodgers Avenue Junction, the Nostrand Avenue Subway (2,5) curves off the mainline tracks, in particular the local tracks. 5 trains even are switched onto the local tracks briefly before continuing switched to continue to south Flatbush Avenue. The only other place on the subway system with this unusual arrangement is the Central Park West Line, there it was done to avoid having station exits directly alongside Central Park.
On the line here, New Lots Avenue-bound trains are on the upper level, with Manhattan-bound trains on the lower level. Fare control is directly along the upper level platform. A bit set back behind the two staircases that lead down to the lower level Manhattan-bound platform. For fare control there is a single bank of turnstiles in front of the token booth with two street stairs out to either side of Nostrand Avenue in the middle of the south mall, where the bike path is (between the main road and service road) of Eastern Parkway.
The platforms themselves have a design of being quite wide towards there middles near the station's exit (here is where there's a line of green I-beam columns), before getting quite narrow towards either end, and all four platforms ending with, at all four extreme ends a section with 1950s style block tiling. Here Nostrand Avenue is written in white on a brown background. The rest of the stations have their original dual-contracts era name tablets and trimlines. The name tablets say Nostrand Avenue on a blue and brown backdrop, with a inner yellow boarder line, and an outer dark brown boarder. The trim-line is a tan yellow for its inner section with a narrow boarder of blue, and a wider outside boarder of a dark brown. There are Ns in the trimline at various intervals for the station's Nostrand Avenue name.
