The Follo Line is not only the biggest infrastructure project taking place in Norway, but also across all of the Nordics – Sweden, Finland, Denmark, and Iceland. Once completed in 2021, the Line will also include the longest railway tunnel in any of the five countries.
At 20km long, it will be Norway’s first long twin-tube rail tunnel, as well as one of the first projects in the country to use Tunnel Boring Machines (TBMs). In total, four TBMs - Queen Eufemia, Queen Ellisiv, Anna from Klokka, and Magda Flatestad - are digging out the tunnels for the tracks. Throughout the construction of the Follo Line, about 10 to 11 million tons of rock spoil will be removed across a period of about 3 to 3.5 years.
