[4] Opening on 6 February 1951, Westall station originally comprised two workers-only platforms for staff at the adjacent Martin & King railway coach-building factory.

[8] In 1985, boom barriers were provided at the former Westall Road level crossing, which was located at the down end of the station.

[9] The station had a stabling yard located at its southern end, as well as a number of industrial sidings serving nearby factories.

The city-bound platform was closed off and passenger services to Flinders Street operated express from Springvale to Clayton, bypassing Westall, until temporary fencing was placed around the building.

In May 2008, the Victorian State Government announced that the Westall station precinct would receive a $151 million upgrade, which included a rebuilt station, a new third platform, a third 2.6-kilometre track between Centre Road and Springvale Road and additional storage space at the Westall stabling yard.
