The station had a single island platform. With the closure of Montgomerie Pier station on 6 May 1968,[1] Winton Pier station became the sole passenger rail terminus at the harbour. When sectorisation was introduced in the 1980s, the station was briefly served by ScotRail before closing, replaced by Ardrossan Harbour railway station (situated slightly further inland) on 19 January 1987 upon the commencement of electric services.[1]
Train services in connection with the sailings of Burns and Laird Lines to Belfast and Isle of Man Steam Packet Company to Douglas, Isle of Man ceased in 1976 and 1985, respectively, when the shipping routes closed.
The site of the station is now located behind the main CalMac ferry terminal building. Only the outline of where the platform was once located remains.
