Long Gully railway station was located in the Belair National Park, South Australia. The original plan was for the siding to be named Minnow. The layout of the passing siding is unusual as, being on an "S" in the main line, traffic in both directions defaulted to the sharper left side while crossing the points to enter the yard. This anomaly was removed when the line was converted to standard gauge in 1995 and the passing siding was replaced by a single line. Long Gully was a very useful station for hikers and bike riders, as the station was located within the national park.
