Oaklands station was opened in 1913, the land having been sold to the State Government by T. C. Tait on the proviso that it be named after his once-extensive property.

[2] Until the early 1950s the Ascot Park and Oaklands stations serviced Marion with a single rail track.

[1] 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.

[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.

The Temporary 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.
