This express station has four tracks and two island platforms. It has three fare control areas at street level—two to Kings Highway / East 16th Street and one to Quentin Road / East 16th Street. The full time mezzanine on the south side of Kings Highway has an extra exit-only on the southbound side. The area on the north side is HEET access only and has no booth, although evidence shows it used to. These two mezzanines are original BMT construction but were fully renovated in the 1980s, during which time two identical sets of porcelain enamel artwork (Kings Highway Hieroglyphs by Rhoda Andors) were installed, one set in each mezzanine. The Quentin Road mezzanine, open weekdays only, was built sometime in the 1950s or 1960s to accommodate growing passenger flow; this is evidenced by its newer-style tiling and signage. Platform extensions are clearly present at the north end of the station.
South of Kings Highway are crossover switches that allow trains to switch from the local tracks to the express ones, and vice versa; these are used when trains must terminate here during construction on the Brighton Line. Before Brighton signal replacement during the 1990s, a switch tower was in operation about 150 feet south of the station, facing the southbound local track; this tower has been abandoned, and control of the switches has passed to a master tower at DeKalb Avenue. During the signal replacement, a new signal electrical tower was installed over the express tracks at the south end of the station.
