The Sydney Metro Inspiro Stock will be a class of electric multiple units that operate on the Sydney Metro network. Built by Siemens Mobility as part of their Inspiro High Capacity (HC) family, the trains are the second fully automated passenger rolling stock in Australia. [1]

A total of 36 carriages, forming 12 3-car trains, have been ordered for the Western Sydney Airport Line, set to open in 2027. [5] [6] [7]

History

Procurement

In 2021, it was announced that three consortia had been shortlisted for the Stations, Systems, Trains, Operations and Maintenance (SSTOM) contract of the Sydney Metro Western Sydney Airport line. [8] 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. [8]

In December 2022, Parklife Metro was selected by Transport for NSW for the SSTOM contract. [9] [10] 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. [11]

In January 2025, a full-size mockup of a train car was presented to assess features including ergonomics, lighting, information screens and emergency systems. [12]

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. [13]

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. [4]

Screens will show real time flight information from Western Sydney Airport. Each train will have 4 bicycle storage spaces. [14]

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. [15]

The trains are approximately 30 cm wider than the existing Alstom Metropolis trains, and will use 25 kV 50 Hz AC electrification unlike the Metro North West & Bankstown Line, meaning the trains will not be interoperable on other lines. [6] As of April 2024, the rolling stock contract for Sydney Metro West has not been awarded. [16] [17]
