The station consisted of two side platforms north of the Oats Street level crossing.

The CircleRoute bus began operating in 1998, allowing access to Curtin University from the Armadale line.

A bus interchange was constructed soon thereafter, and Oats Street soon became one of the most important stations on the Armadale line.

Oats Street station is on the boundary of Carlisle and East Victoria Park, which are suburbs of Perth, Western Australia.

[1] The station is along the South Western Railway, which links Perth and Bunbury,[2] and is owned by the Public Transport Authority (PTA).

[4][1] The surrounding area predominantly consists of low-density residential development, with some light industrial properties to the south.

There is also the Carlisle campus of the South Metropolitan TAFE, directly to the west of Oats Street station.

The diesel railcars had faster acceleration than steam trains, which allowed for more stations to open.

A new master plan was released in August 2002, which cancelled all proposed works at Oats Street station.

[21][22] Following the Labor Party's successful election, Metronet was formed to manage upgrades to Perth's rail network.

Town of Victoria Park mayor Karen Vernon criticised the decision to go with an elevated railway, instead wanting it to be underground.

[27][28][29] It was announced in February 2022 that to build the elevated railway, the Armadale and Thornlie lines would have to shut down for 18 months.

Each entrance building will have one lift and one set of stairs to each platform, with provisions for escalators in the future.

The station will be positioned on the southern side of the rail corridor, which will allow for expansion to four tracks in the future.

The Armadale line had 15 minute headways all week, with three extra trains during peak hour.

The Thornlie line had 15 minute headways from Monday to Saturday, dropping to every half an hour on Sundays and at night.
