The AirTrain station, located in an enclosed glass structure to the south of the LIRR platforms, has 2 tracks and 1 island platform. It is accessed by escalator or elevator from street level as well as via an enclosed bridge connecting it to the LIRR station. Unlike the LIRR platforms, the AirTrain JFK platforms are entirely enclosed and feature platform screen doors, which help the station maintain a constant temperature and prevent passengers from falling onto the tracks. An array of sensors detect a train's position on the track, and only when it is properly aligned will the train's doors open. This enables the AirTrain to use automatic train operation.
