[citation needed] The platforms were constructed of earth-filled concrete each side of the dual tracks, which were both broad gauge until 1995.

There were timber framed, iron clad open passenger shelters on each platform.

Millswood station closed on 28 April 1995, simultaneously with stations at Clapham and Hawthorn despite criticism from nearby residents, with the conversion of the Adelaide-Wolseley line to standard gauge under the One Nation programme.

[2] A number of reasons were quoted as justification for the closures, including poor patronage,[3] the excessive number of stations between Goodwood and Lynton and their proximity to each other, and the impracticability of a single-line working with so many stations and so few crossing points.

[citation needed] In August 2013, moves were made towards the reopening of Millswood station, with the Transport Department launching an investigation into the proposal.
