Just south of the station, the line from Adelaide becomes single track for the remainder of the journey to Outer Harbor. It once had two platforms but one closed in the 1980s when the balloon loop north was removed. The unused track was gradually removed, with the last remnants at the level crossing next to the station pulled up in July 2019. Just south of the station, the ICI Osborne railway line branched off to the ICI Osborne works (later owned by Penrice Soda Products). This had industrial passenger service until 1980 and has since been dismantled. Some peak hour services from Adelaide terminate at Osborne.
