World leader in implementing ERTMS
Our excellent engineering skills have enabled us to overcome the challenges of Spain’s difficult and rather complicated landscape, designing and building some of the longest tunnels in the world and constructing internationally renowned viaducts:
- Guadarrama Tunnel: 28.4 km. 4th longest in Europe and 5th longest in the world.
- Pajares Tunnel: 24.9 km. 5th longest in Europe.
- Contreras Viaduct: 587 m. The biggest concrete railway bridge (261 m span) in Europe.
We have also participated in the extension, planning and construction of the main network stations linking Spanish cities, with extremely complex engineering projects such as the connection between Atocha and Chamartín consisting of a tunnel over 7 km long that will link all the high speed lines passing through Madrid.
