Siemens Mobility to invest £100m in state-of-the-art UK factory

Siemens is embarking on a groundbreaking £100 million investment to establish a cutting-edge rail infrastructure manufacturing, digital engineering and research & development (R&D) centre in Chippenham, underscoring its unwavering commitment to innovation, sustainability, excellence, and its campaign ‘to build in Britain with Britain built in’.  

The new facility, set to replace the existing factory in 2026, is poised to be a cornerstone for Siemens’ future projects in rail technology, providing an efficient site to build the next generation of conventional and digital rail signaling and control systems for Britain. The transition, including the transfer of all local staff, totaling around 800, will not cause any interruption in production. 

Chancellor of the Exchequer Jeremy Hunt said: “This new commitment from Siemens is a big boost for Britain’s world-class manufacturing sector and shows our plan for the UK to be the best place to invest and grow a business is working. 

“This digital technology will improve the safety, reliability and connectivity of our railways and drive sustainable opportunities in higher-paid jobs and exports – as part of our plan to grow our economy.” 

Rob Morris, Joint CEO of Siemens Mobility in the UK & Ireland said: “This £100 million investment is a strong commitment to Chippenham and our country. Siemens Mobility’s Chippenham site, along with our 30 sites across the country, has been transforming rail travel and transport in Britain – and it will continue to do so with cloud-based rail technology connecting the real and the digital worlds, digitalizing rail. We are very excited to soon start construction of one of the most sophisticated rail factories, digital engineering and R&D sites in the UK, supporting local jobs and skills for the future. There’s a piece of Britain in everything we build.” 

Siemens’ new Chippenham site 

Siemens’ new Chippenham site, located south of Langley Park at SouthPoint Business Park, will feature an office built to the highest BREEAM ‘Excellent’ standard. The production and warehouse areas will meet strict sustainability criteria, evaluated across various categories including energy, water, waste, health, well-being, or materials. This promotes structures that are more sustainable and beneficial for society and the environment.  

The factory is being constructed with the latest standards for highly efficient production, while the offices are designed to provide a modern, welcoming work environment to enable better collaboration and innovation for the UK railway. The interior will be modelled to account for the ‘new normal’ with many open and collaboration and meeting spaces, better facilities, relaxation areas and improved technology. The site, designed to blend in with its surroundings, will undergo an ecological assessment aiming for a 10% net increase in biodiversity through the planting of native plants and the creation of wildlife habitats. 

Legacy of Excellence: Siemens in Chippenham 

Chippenham, the UK’s sole dedicated signaling and control facility, has been integral to Siemens’ success in the United Kingdom and globally. The current factory, a hub for designing, manufacturing, and delivering signaling and control systems, has played a pivotal role in major projects such as the Elizabeth line, North Wales Coast, Birmingham New Street, and numerous global initiatives. 

The current Siemens factory in Chippenham has a rich history, dating back to its establishment by signaling contractor Evans O’Donnell in 1897. Over the years, it underwent various transitions, including being acquired by the Westinghouse Brake & Signaling Company, before becoming part of Siemens global network of rail infrastructure production facilities in 2013. Siemens Mobility, a global leader in intelligent transport solutions, has been at the forefront of rail technology for over 175 years.
