It includes the electrification of two currently existing regional lines to Melton and Wyndham Vale, and other network capacity upgrades.

[2] Staging of the works component of the plan are being developed alongside the business case for the Melbourne Airport Rail Link.

[10] Part of the line between Melton and Deer Park was duplicated during the Regional Rail Revival Project, which made provision for electrification and a future increase in services.

[11] Electrification to Melton would potentially triple the carrying capacity of the line, and will allow up to 1500 people to travel on a single train.

Two level crossings located in Deer Park would be removed to allow trains to run on the line at a higher frequency.

Prior to the 2022 Victorian state election, the Andrews Labor Government announced that Tarneit West would be built and planning works for Truganina would begin.
