It is located 21.7 kilometres from the Adelaide station. The station was located parallel to Langford Terrace, adjacent to the freight train line, and inline roughly to Compton Street. The station was opened in 1941 along with the Penfield line. The station name is derived from the "native word for wind". The station was different from the others as it had up and down stepdown platforms about 61 metres long. The station was unstaffed and had a small shelter.
