Ascot Park railway station is located on the Seaford line. Situated in the south-western Adelaide suburb of Ascot Park, it is 10.2 kilometres from Adelaide station. The station has two tracks, either side of an island platform with a pedestrian subway connecting the platform to the two adjacent streets. The station is located just south of where the Tonsley line branches off. The original 1914 station building was demolished and replaced with the current shelter in the 1970s.
