Originally budgeted at $1.1 billion, the total cost of the project has escalated to $1.65 billion, with the Federal government contributing $700 million in 2017.

WA Premier Roger Cook emphasized that his government initiated the project from scratch, following the previous Liberal government's unfulfilled promises made in 2008 and 2013.

The population of Ellenbrook has surged to over 25,000, making it one of the fastest-growing and most car-dependent areas in Western Australia.

The new rail line spans 21 kilometers and will significantly reduce travel time from Ellenbrook to Perth's CBD from one hour by car to just 30 minutes by train.

Transport Minister Rita Saffioti anticipates that around 3,000 people will board the train daily at the Ballajura station.

Stations along the new line will include Morley, Noranda, Ballajura, Whiteman Park, and Ellenbrook.

Fares for the train will be capped at approximately $4 per trip, with free travel available for school students and Sunday commuters.

Saffioti expressed uncertainty about inviting former WA Premier Colin Barnett to the opening event, noting his presence at the opening of Optus Stadium in 2018.

The long-awaited Ellenbrook train line, which has been in the works since its promise in 2008, is set to open to the public on December 8, 2023, marking a 16-year wait for local residents.
