PROJECT FOLLO LINE

Follo Line

For the Follo Line in Norway, the longest railway tunnel in the Nordic region, we engineered a comprehensive solution for critical secondary structures. Working alongside the Acciona Ghella Joint Venture and Actyon Norway, we deployed custom rail mounted formwork carriages to construct access tunnels and safety galleries across the 20 kilometer twin tubes. Our hydraulic modular steel travelers streamlined the concreting process, ensuring high precision and smooth finishes in confined underground spaces. By eliminating heavy crane dependency and maximizing equipment reusability, we accelerated the execution of evacuation platforms and technical zones, playing a vital role in the successful opening of this landmark high speed rail link.
