Oaklands railway station

In 2011-2012, the state government undertook a planning study into a grade separation project to eliminate the level crossing south of the station by building an underpass beneath the railway line for Diagonal Road.[6] No funding was provided at that time. Work began in 2018 to lower the railway line under the road instead.[7] The contract to design and build the new crossing was awarded on 16 January 2018 to the Public Transport Projects Alliance,[8] a joint venture of McConnell Dowell, Mott MacDonald and Arup Group.[9] During construction in late 2018, the government proposed a renaming of the station to Marion Centre to better reflect its location near the Westfield Marion Shopping Centre, Marion Cultural Centre and the State Aquatic Centre.[10][11] However, the proposed renaming did not materialise.

Oaklands station was permanently closed on 13 April 2019 and demolished as works commenced to realign the tracks to the newly-constructed underpass; the Seaford Line was also temporarily closed between Brighton and Adelaide to allow the electric catenary for the trains to be shut off for the final works. The new grade separated station features ramps and stairs down to platform level and has public toilet facilities at street level.[12] The line was reopened on 6 May 2019 and trains commenced servicing the new station the same day.[13]
