Blairstown was one of the three original Delaware, Lackawanna and Western Railroad stations on the Lackawanna Cut-Off rail line in northwestern New Jersey. Built by contractor Hyde, McFarlan & Burke, the station opened in 1911. Most passenger trains, such as the Lackawanna Limited and, later, the Phoebe Snow, plus the Twilight/Pocono Express and the Westerner/New Yorker stopped at Blairstown, which also sold commuter tickets. Blairstown station was the only station on the Cut-Off to be open during the Erie Lackawanna Railway years, and remained so until passenger service ended on January 6, 1970 with the discontinuing of the Lake Cities. After 1970, the building housed a radio station, WHCY-FM, until the 1990s. The station building is currently privately owned.
