Stable tracks require a steady ground and solid constructions. Due to the irregular ground of the Nordic landscape, this often mean quite an effort. The ground work includes, among others, excavations, transport, sorting of masses, ditching and preparation of water and drainage systems.

We take on large and small concrete works. As far as possible, we prefer utilising low-carbon concrete, and we always strive for optimising concrete volumes.

The signaling system ensures safety, speed, and time management for trains on the move. If failure occurs, human or technical, the signaling system will notice and warn immediately.

The future railways are 100% electric – no surprise this requires amounts of power. The solution is several generating stations along the lines, supplying the trains with electricity.

Telecom

No communication, no train service. The digital telecom systems are essential to ensure connection between crew and operators, control of technical facilities, as well as information to passengers. This is an attractive field for anyone interested in radio and transmission systems.

The overhead contact line system consists of different components needed to ensure supply of power to the electric track operations. This includes wires, masts, switches and systems leading the return current.

We are the leading rail infrastructure company in the Nordics. We build and construct new tracks for cities to connect. We also maintain old tracks to secure safe transport for passengers and goods for decades.

Everything comes to an end, even railway lines. Have you ever wondered where trains spend the nights, where the cabins are cleaned and where the failures are fixed? Well-functioning terminal buildings are important for any railway service.
