Alstom Group is a French public company headquartered in Saint-Ouen-sur-Seine that designs, manufactures and maintains rail transport systems worldwide. Now focused solely on mobility following the divestment of its energy businesses, it is active across passenger transport, rail services, signalling and locomotives, producing high-speed, regional, suburban and urban trains along with trams. Its portfolio spans rolling stock, signalling, components, infrastructure, digital rail and turnkey systems, which can be supplied either separately or as integrated solutions.
Alstom reports revenue of about €18.5 billion and a workforce of more than 80,000 employees, and in 2025/26 it disclosed a record order backlog of around €100 billion. The group operates through engineering centres, manufacturing plants and joint ventures across Europe, the Americas, Asia-Pacific, the Middle East and Africa, with significant footprints in France, Canada, China and the United States. In France it is a key partner to SNCF and RATP and is expanding capacity for its Avelia very high‑speed train platform, including new and enlarged assembly lines and a major investment programme at sites such as Valenciennes, La Rochelle and Belfort. In North America it manufactures and services metro, commuter and light rail fleets for networks including Montreal’s REM, Toronto and Vancouver, while its Chinese joint ventures deliver high‑speed trains, metros, monorails, components and signalling for more than 100 urban lines.
Strategically, Alstom positions rail as the backbone of low‑carbon mobility and commits to “smart and sustainable” solutions. Its Metropolis metro platform, Avelia high‑speed family and Citadis tram range illustrate its focus on energy‑efficient traction, automation and digital control. Group‑wide commitments include innovating fossil‑free transport technologies, applying eco‑design and circular principles, supporting local socio‑economic development, and advancing health, safety and diversity across its global workforce.
