The project consists in the upgrade a 13.6-kilometre section of a railway line between the towns of Nykirke and Barkaker, south of Oslo.

A double-track line, including 3 bridges, 3 tunnels (Gråmunk and Skottås tunnels in drill&blast, Kopstad tunnel in cut&cover) and a station near the town of Skoppum.

The project concerns a section of the so-called Vestfold Line, which is being modernized to reduce travel times and increase railway passenger capacity. Norway has as one of its priorities the establishment of a continuous double-track rail line between Oslo and Tønsberg by 2024.

Once it is upgraded, travel time between the two cities will be about an hour, with a frequency of up to four trains an hour in either direction. The project will also favour economic development beyond the Norwegian capital.
