Sustainable large-scale infrastructures, respecting of the environment

At IDOM, we have been working on high-speed, conventional and freight rail for more than 20 years, designing thousands of kilometers for large-scale projects, from conception to operation and maintenance of these large infrastructures.

We develop cutting-edge projects, clean and efficient transport systems, using the most innovative technologies and resilient solutions, which solve the challenges of changing environments, always taking into account passenger comfort, the highest standards of accessibility and the sustainability of the environment.

The IDOM team combines all the railway disciplines: civil works, superstructure (track, electrification, signaling and communications), station architecture, rolling stock, commissioning, operation plans, maintenance and RAMS.
