On December 12, 2022, the new 250km/h high-speed line from Oslo to Ski was put into operation in Norway. This is the largest Norwegian transport project to date and the longest rail tunnel in Scandinavia.
Commuters and other rail travelers will be able to travel faster from Oslo to Ski on the new 22km double-track high-speed Follobanen line, which mainly consists of the 19.5km twin-tube Blix Tunnel. With the new trial speed of 200km/h, the travel time on this connection has already been halved, from 22 to 11 minutes.
