PTA requires responses to the RFQ by June 7. Shortlisted bidders will progress to an interactive tendering process before a final supplier is chosen next year.

The successful bidder will be required to manufacture or assemble 50% of the trains in Western Australia. Delivery of the 17 Metronet trains, known as the C-series, is due to begin in 2021. PTA wants the remaining 24 trains to enter service between 2023 and 2028.
