Sydney Metro Inspiro Stock

History

Procurement

In 2021, it was announced that three consortia had been shortlisted for the Stations, Systems, Trains, Operations and Maintenance contract of the Sydney Metro Western Sydney Airport line. The winning consortium would build the stations and trains, install signalling and other electronic systems, as well as operate and maintain the line as a public–private partnership.

Bradfield Metro, comprising John Laing, Keolis Downer, FCC Construction Australia and Hitachi Rail STS
Parklife Metro, comprising Plenary Group, Webuild, RATP Dev and four Siemens Mobility companies
WestGo, comprising CIMIC Group, two Acciona companies, DIF Management Australia, ComfortDelGro Transit and Coleman Rail Pty Ltd

In December 2022, Parklife Metro was selected by Transport for NSW for the SSTOM contract. Siemens would provide 12 3-car trains, together with 15 years of maintenance, as well as signalling, electrification, communication systems, platform screen doors and the depot at a cost of €900 million.
In January 2025, a full-size mockup of a train car was presented to assess features including ergonomics, lighting, information screens and emergency systems.

Design

The seat upholstery draws inspiration from the Cumberland Plain, where the line is located. It was designed by BBR, led by Dharug artist, Leanne Redpath, with Tina Barahanos and Alexandra Byrne. The design is named Ngurra Baduwa, referring to "country" and water. Priority seats will be yellow, representing scenes of meeting places around waterholes, with wattle flowers. Seat upholstery will require approximately 2,300 m² of fabric.

Specifications

Each car will have 3 double doors per side, and will have open gangways. Trains will have step-free access, with wheelchair spaces and hearing loops in every car. Both longitudinal and transverse seats will be used, alongside "multifunctional" areas with tip-up seats. Seats are designed to allow under-seat luggage storage, with headrests provided on transverse seats. There will be 2 redundant air-conditioning units per car alongside floor heating.
Screens will show real time flight information from Western Sydney Airport. Each train will have 4 bicycle storage spaces.
The trains will make use of Siemens' Railigent X asset management system for predictive maintenance, involving a failure reporting, analysis, and corrective action system and reliability-centered maintenance concepts.
The trains are approximately 30 cm wider than the existing Alstom Metropolis trains, and will use electrification unlike the Metro North West & Bankstown Line, meaning the trains will not be interoperable on other lines., the rolling stock contract for Sydney Metro West has not been awarded.
