The $A 1.6bn ($US 1.08bn) fleet will comprise 102 vehicles for the Metronet expansion and 144 vehicles to replace the Transperth A Series EMUs built in 1991-1999.
The six-car 25kV ac trains will feature LED lighting, USB charging points and wider passenger doors to improve passenger flow at stations. Each 145m-long train will accommodate up to 1200 passengers.
At least 50% of the C Series vehicles will be assembled at a purpose-built facility at Bellevue east of Perth, which is expected to create 200 direct jobs. Construction of the plant will begin next year and is due to be completed in 2021.
Under the 30-year maintenance agreement, Alstom will maintain the fleet at a new 12,000m2 depot near Midland.
Metronet says it is now working closely with Alstom on the final contract negotiations and aims to finalise the deal towards the end of the year.
The first Metronet C Series trains are due to enter service in the Mandurah and Joondalup lines from 2022.
