The Follo Line Project is currently the largest infrastructure project in Norway and will include the longest railway tunnel in the Nordic countries. This fact sheet presents four different parts of the Follo Line Project giving a short description of status and the work to be executed by the entrepreneurs, with Bane NOR as client.

What is the Follo Line Project?
The Follo Line Project is a part of the larger InterCity development in the Oslo region. The project includes a new double track line between Oslo Central Station and the regional town Ski. The new railway consists of a 20 km long twin rail tunnel and will reduce the total travel time from 22 minutes to 11 minutes. The main construction work started in 2015, and completion is scheduled for December 2021.

A Pilot Project
The large scale project is under production simultaneously from five different work sites from Oslo to Ski. With its novel methods and solutions, this project offers a model for future railway project developments in the region. Four tunnel boring machines are being operated simultaneously from one big scale rig area for the first time in Europe.
