Colas Rail

Colas Rail is one of Europe’s leading suppliers of railway infrastructure services. Colas Rail's experience in the railway sector means it can offer turnkey solutions and meet all the requirements of new high-speed lines (LGV), network maintenance and urban transport (trams, metros).
Colas Rail was born from the merger between Seco Rail and Spie Rail in January 2008. The merger brought together two of the world's major players in the railway sector and pooled their respective skills within one entity. Spie Rail's and Seco Rail's activities were complementary. Together they offer a world-scale, high-end railway expertise through one and the same company: Colas Rail.
This reflects its recognised competence in:
- Management of turnkey railway projects
- Overhead lines
- Electro-mechanical activities
- Electric power supply
- Signalling
- Manufacturing sleepers
- Rail freight
- COSS: controller of site safety (warning activity)
- Rolling stock maintenance
Colas Rail today is one of the major players in the railway sector.
