the longest rail tunnel in the Nordic countries • Excavated mainly with tunnel boring machines (TBM), but also by drill/blast and drill & split • The first long railway tunnel in Norway with separate twin tunnels (each 18,5 km long) • Will enable a 50 % reduction in journey time Oslo-Ski/ • Designed for speed up to 250 km/h • Part of the Norwegian InterCity rail development project Thank you Bane NOR The state-owned Norwegian company responsible for the national railway infrastructure Management and maintenance Construction and renewal Operation and traffic control .
