Civil engineering comprises Infranord’s second-largest business area, and our market share in Sweden is just over 15% of the market’s total volume.

A modern and efficient railway means that more journeys and freight shipments can be shifted to rail from road and air, thus enabling a more long-term sustainable society. We have extensive civil engineering experience and expertise and work with our own unique plant according to tried and tested working methods that ensure efficiency and quality.

Assignments may include new construction or the replacement of rails, installing new or remodelling signalling systems and signal boxes, overhead line work, replacement of sleepers and switches, and complex signalling installations. Some projects, such as remodelling marshalling yards and platforms, are among the most challenging in railway engineering and require cutting-edge expertise and many years of experience. Infranord has both the experience and the knowledge required.
