Spain’s high speed network covers over 3,000 kilometers of track, and is the longest in Europe and the second longest in the world. The system transports 17 million passengers at speeds exceeding 350 km/hr, connecting them to major Spanish cities.

From its beginnings, Ineco has been involved in the implementation of the Spanish high speed rail network, and was active in the planning, design, and technological development, to achieve a safer and more efficient railway system.

Over 25 years experience in design, construction, signalling, communications, maintenance and traffic management projects, for greater efficiency and safety.

Engineering challenges

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.
