High Speed Rail

We are a world leader in the design, construction, renewal and maintenance of high speed lines.

Since completing our first high speed scheme in 1981 we have worked on circa 3000km of high speed line including recent schemes at Rennes-Le Mans and Nimes-Montpellier in France and Tangier-Kenitra in Morocco, all of which are commissioning and coming into service in 2017/18.
