The original Warwick Farm station opened on 18 March 1889 as a private platform for
William Forrester near the former level crossing on the
Hume Highway. It was relocated to its present location in 1943 when nearby
Warwick Farm Racecourse was used as a military camp. Previously, a 1.6-kilometre branch line to
Warwick Farm Racecourse branched off from the
Main South line north of the station, and carried special racecourse trains on race days. The branch opened in June 1889, closed in August 1990 and was removed in December 1991. The
Southern Sydney Freight Line opened immediately to the east of the station in January 2013. As part of its construction, a footbridge with lifts and stairs was constructed. Previously, crossing the railway line required passengers to use the Hume Highway bridge. Platform 2 was very narrow and was widened during the works. The station briefly received national attention in April 2024 after an unusual incident where a
thoroughbred wandered onto the station platform. It was one of four escaped racehorses from a Warwick Farm stable complex, who were released by an unknown person. The horses were recaptured and returned to their stables shortly after.
