Alstom in the UK and Ireland

Alstom is the UK & Ireland’s leading supplier of new trains and train services, and a leading signalling and rail infrastructure provider. Alstom have built, or are building, just under 40% of the UK mainline train fleet; as well as the entire fleets in service with London Underground and Dublin Luas.

We provide the widest range of smart solutions in the rail market, from innovative high-speed rolling stock, metros and trams to maintenance, modernisation, infrastructure and signalling.

Employing 6000 people, we design and build trains at Derby, the UK’s largest train factory; and operate major sites at Widnes, Crewe, Ilford and Plymouth, and 30 train services depots across the UK and Ireland.  

Sustainability vision

Alstom recognises the importance of implementing a sustainable business model which supports the transition to sustainable transport systems in order to ensure the long-term success of our planet. As a sustainable business by nature, we pride ourselves on delivering a wide range of innovative and environmentally friendly technologies and solutions.


"Alstom UK and Ireland commit to embedding sustainability into every element of our organisation – from reducing the carbon footprint of our work sites through to increasing the diversity of the rail industry workforce."

The UK’s New Green Age: a step change in transport

Decarbonisation calls for a £10bn investment programme in UK rail and mass transit systems, after research revealed that the UK has opportunities to improve infrastructure, learning lessons from international examples. As well as the economic benefits, the report reveals the true scale of environmental advancements that these schemes bring, including tackling carbon emissions, cleaning air and supporting modal shift.

To support green transport options the report also calls for rolling out fleets of clean, zero emission hydrogen trains to replace polluting diesels and investment to speed up electrification projects and support initiatives such as Northern Powerhouse Rail and Midlands Engine Rail. These will all serve the multiple purposes of benefiting the economy, jobs, and our environment.
