The Government of West Australia has selected Alstom as the preferred bidder to supply 252 electric multiple-unit cars.
As per the terms of the agreement, the French rolling stock manufacturer will deliver 246 C-series railcars and six DMU cars to replace the existing Australind service.
The contract, which is expected to be finalised later this year, is budgeted at A$1.6bn ($1.08bn) over ten years.
Of the 246 railcars, 102 will be for the Metronet rail expansion and the remaining 144 will replace the ageing A-Series railcars.
Alstom will also be responsible for maintaining the fleet for the next 30 years.
As per the agreement, Alstom will manufacture 50% of the railcars in West Australia. It will create more than 200 direct and long-term jobs, as well as hundreds of additional indirect jobs
The French firm will establish a base at the 12,000m² plant near Midland.
Stage one of the construction, which is expected to start next year, will be carried out in Bellevue plant. It will be completed in 2021.
The remaining stages, including the new railcar depot and diesel facility, will continue until 2023.
The trains will operate on the Mandurah and Joondalup Lines from 2022 and will have an operational life of 35 years.
They will be equipped with USB charging points, LED lighting and regenerative braking. Each train will comprise of six-cars with a capacity to accommodate 1200 passengers.
Western Australian Premier Mark McGowan said: “These are Western Australian (WA) trains, so they should be WA jobs.
“Currently the work carried out locally is limited to window tinting and passenger seating, just two per cent of the work, WA can do so much more than that.
“So we’re bringing railcar manufacturing back to WA and back to its home in the Midland area, with a new railcar facility in Bellevue.”
Earlier this month, Alstom received an order to deliver 13 trains to the Hello Paris consortium, which operates the CDG Express.
Under the €160m contract, Alstom will deliver trains based on the Coradia Polyvalent range.
