London’s Elizabeth line enters passenger service utilising Alstom’s state-of-the-art Aventra fleet and critical infrastructure

“The Elizabeth line is set to transform London and become one of the world’s leading urban transport operations. I’m immensely proud of the leading role Alstom has played in the Crossrail project, and will continue to do so delivering reliable, high-quality trains for Londoners,” states Nick Crossfield, Alstom Managing Director, UK & Ireland.

The new railway through central London uses Alstom’s Class 345 Aventra fleet between London Paddington and Abbey Wood station. The state-of-the-art trains, already in service between Paddington, Heathrow Airport and Reading on the west, and also run between London Liverpool Street and Shenfield on the east. The seventy 7- and 9-car trains have been designed and built at Alstom’s Derby factory and are maintained by Alstom at Old Oak Common depot in West London.  Alstom will maintain the trains for the next 32 years as part of the rolling stock and services provision contract.

The Alstom-led ATC joint venture, formed with partners TSO and Costain, has designed, constructed, tested and commissioned critical infrastructure works for the new 55-kilometre line. ATC has delivered the traction power supply for the trains, incorporating Alstom’s in-house feeding systems, non-traction power supplies for the stations, shafts and portals, tunnel ventilation systems and other electrical and mechanical systems, laid the track (including 5500 HAS sleepers), and built a new maintenance depot at Plumstead. ATC has been the Principal Contractor for the entire railway construction, managing safety, logistics, testing and commissioning between more than twenty interfacing contractors.

Andy Byford, London’s Transport Commissioner, said: “Alstom UK has been a key delivery partner in the Elizabeth line and played a major part making it possible to open this transformational railway today. Providing trains, technology, infrastructure and maintenance, they will help ensure Londoners and visitors benefit from reliable and more accessible journeys across the capital.”
