We are proud of our track record in global railway projects helping cities and countries across the world achieve their transportation needs and sustainability goals.

With over 20 years’ international experience designing light rail, conventional rail and high speed rail, our UK rail team has developed with the advantage of the specialisms and experience of our railway engineers across IDOM offices worldwide.

Our international case studies cover all aspects of rail design from feasibility studies to detailed design and construction supervision of more than 4,000 km of railways across Europe, Asia and America.

The philosophy and project-based culture of Idom ensures that our team in UK collaborates in international IDOM Group rail projects. For example our UK team was actively involved in railway innovation and research, bringing to the table new rail technology and designs that will benefit Britain’s railways. Our multidiscipline UK team covers all the required specialisms including civil engineering, superstructure (track, electrification, signalling and comms), rolling stock, operational plans, maintenance and RAMS.

We are RISQS Certified and have NR approved Contractor’s Responsible Engineers (CRE).
