the Metropolitan Transportation Authority (MTA) has withheld approvals to construct a southbound platform. Station layout Located on an embankment, the station has four tracks with only the outer two used in revenue service. The two center express tracks have been disconnected from the line and permanently removed. North of this station, a portion of the southbound express track connects with the southbound local track at its north end, and ends at a bumper block at its southern end. This section of track can be used for revenue service or work train layups, but this use has been made completely redundant because of the nearby Pitkin Yard serving as the primary layup yard instead. North of the station, the line's northbound track switches to the position of the former southbound express track to head onto the Liberty Avenue elevated structure. The station is the only through stop in the New York City Subway to serve trains in a single direction. There is one side platform located on the northbound side, with one exit leading directly to Aqueduct Racetrack, serving northbound trains heading toward Brooklyn and Manhattan. Southbound trains do not serve the station but stop at the Aqueduct–North Conduit Avenue station, to the south. In the past, southbound trains have terminated at this station using a crossover located to the north of the station. This station was originally advertised as "open on racing days", but some trains stopped here regardless of the time of day; riders could not always exit the station, depending on whether the racetrack was open. Resorts World Casino runs a shuttle bus between Aqueduct Racetrack and Aqueduct–North Conduit Avenue. Exits This station has four High Entrance/Exit Turnstiles and several emergency exit gates (one of which is equipped with an AutoGate MetroCard reader), but no station agent's booth or MetroCard Vending Machines. Although MetroCards can technically be purchased at any subway station in the system, the Metropolitan Transportation Authority (MTA) considers the station to be linked with Aqueduct–North Conduit Avenue located approximately to the south, which has a full-time station agent's booth and MetroCard machines. Two wide staircases and the elevator lead down from platform level to the parking lots in front of the racetrack. A sidewalk on the western side of Aqueduct Road leads south from Aqueduct Racetrack to the North Conduit Avenue station; the main fare control area is located at the south end of that
