The Follo line is a 22 km new double-track from the capital of Oslo to suburban town of Ski. Combined with the existing Østfold line, the Follo line will bring a new era for rail travel in southeastern Norway. Four tracks into Oslo will allow more trains to run – faster and on time.
Today, capacity on the exisisting Østfold line is stretched to the limit. Improving capacity south of Oslo is vital in order to increase rail transport locally and nationally – for both freight and passenger traffic.
By separating express trains from the slower, local trains, the the Follo line will shorten travel time, improve punctuality and more than double capacity.
Rock tunnels will constitute as much as 19 km of the projected line. Apart from the rock tunnel twin tubes, the project includes a new station at Ski, a passing loop at Ås and a cut-off at Bryn, which eventually will connect the Follo line with the Alnabru container terminal.
Construction will start in 2013, depending on public funding. Both TBM and drill and blast are considered as excavation methods for the tunnel.
