Transperth C-series train

The Transperth C-series trains are a class of electric multiple units part of Alstom's X'Trapolis family of trains for Transperth that are being delivered as part of Metronet. The trains are operating on Perth's suburban rail network and entered service on the Yanchep and Mandurah lines on 8 April 2024.

History
In April 2018, the Public Transport Authority called for expressions of interest to build 41 6-carriage electric multiple units. Three consortia were shortlisted to bid:
 * Alstom
 * Bombardier / EDI Rail
 * Momentum West, a consortium of CAF and UGL

On 18 August 2019, Alstom was announced as the successful bidder. The trains will be assembled in Bellevue. Twenty-five sets will be delivered to provide rolling stock for network extensions as part of the Metronet project, while the other sixteen will replace the A-series stock from 2024.



In December 2019, Alstom released details of the contract and early renders of what the new trains will look like. Under the contract, worth approximately €800 million (AUD1.3 billion), Alstom will be responsible for the design, supply, manufacturing, testing and commissioning of 41 six-car electric-multiple-unit (EMU) trains for suburban services and two, three-car diesel-multiple-unit (DMU) trains for the Australind, which includes 50% local content, twenty years maintenance of the EMU trains and maintenance support services for the DMU trains.

From 3 April to 18 April 2021, a two thirds length mock-up of a single carriage was made available for the general public to view and provide feedback at Yagan Square. Notable features of the new trains include a mixture of high back seats and bench seating, graphical passenger information displays (that are used the same as it’s predecessors in service), USB ports and hard-worn flooring instead of the carpet-laid floors of previous trains. Later, the train mock-up was seen in the 2023 Perth Royal Show

On 7 June 2021 (Western Australia Day), the Railcar Manufacturing and Assembly Facility was officially opened at the Bellevue Railcar Depot, and handed over to Alstom to commence manufacturing the trains. The first train was revealed on 14 August 2022, with twelve months of testing along the Joondalup and Mandurah lines set to occur before they are put in passenger service. Testing along the Joondalup line between Clarkson station and Butler station commenced on 23 December 2022.

The trains entered service on the Joondalup and Mandurah lines on 8 April 2024. A commemorative "first journey" occurred the day before on April 7, with tickets to that open to the public via a lottery. As of 14 July 2024, there are three C-series trains in service.
