Roselle Park and Union stations, which are located on Conrail Shared Assets Operation's (CSAO) Lehigh Line in New Jersey, are equipped with gauntlet tracks. As New Jersey Transit's "Raritan Valley Line" trains use these stations, as well as freight trains of CSAO use this track, the gauntlet track allows freight trains the extra clearance they may require, by moving the train further away from the platform edge (or, rather, the gauntlet track allows the passenger train to get closer to the platform). The gauntlet track is equipped with dispatcher controlled power switches.
