Siemens Mobility is at the forefront of transforming rail travel and transport in Britain. With 5,500 dedicated UK employees, we design, build, and maintain cutting-edge rail solutions, from trains to vital infrastructure. Our commitment to innovation is evident across our three manufacturing sites: Chippenham (signalling, R&D), Ashby-de-la-Zouch (control systems), and Goole, where we manufacture trains, including London Underground's Piccadilly line fleet.
We proudly support the UK economy, collaborating with 1,860 UK-based suppliers and operating from 30 locations, including 13 train maintenance sites. Our trains make up almost quarter of the UK's passenger fleet.
Looking ahead, Goole will be home to the production of our revolutionary Desiro Verve battery trains, which offer an integrated, sustainable solution to replace aging diesel fleets for the new era of Great British Railways. By combining advanced battery bi-mode trains with discontinuous electrification and fast-charging capabilities, we provide a smart, scalable, and cost-effective alternative. This innovative approach could save the UK £3.5 billion in maintenance and operational costs over 35 years, delivering a low-carbon future for routes not fully electrified.
Siemens Mobility's significant investment of up to £340 million across the UK underscores our dedication to sustainable transport, technology, job creation, and economic growth.

The project places the UK rail supply chain at the heart of its delivery, with a substantial commitment to UK content across materials, equipment and specialist services. Under a recent agreement, British Steel will manufacture 36,000 tonnes of rail in Scunthorpe, creating 23 skilled roles and enabling the plant to resume continuous rail production.

With 60 years of experience and over US$20 billion of projects delivered worldwide, ERG International Group combines capability with a long-term commitment to British industry.
