Ulvin Tunnel

Historie

The Ulvin Tunnel is a 3985m railway tunnel running through Morskogen and Ulvin in Eidsvoll, Norway. The single-tube tunnel carried double track of the Dovre Line, allowing it to bypass the village of Morskogen. Construction was part of a 17km new double track between Langset and Kleverud. This was built jointly with the new European Road E6 four-lane motorway. The Ulvin Tunnel will allow for higher speeds and more traffic on the Dovre Line.The Ulvin Tunnel runs in the same area as the Morskogen Tunnel of said motorway. The route was controversial due to it hugging the shoreline of the lake Mjøsa. Local and environmental authorities wanted most of the railway and motorway to run in tunnels. It resulted in a compromise, where the Ulvin Tunnel allowed for a longer section of lakeshore to remain untouched. The groundwork contract was awarded to Veidekke and Hochtief, along with other works. The permanent way was laid by Infranord; Eltel installed the electrical and telecommunications systems. The tunnel is scheduled for opening on 23 November 2015.SpecificationsThe Ulvin Tunnel is 3985m long and runs roughly north–south through the Ulvin area in Eidsvoll. It is built with a curve, allowing the Dovre Line to bypass the village of Morskogen. The single-tube tunnel is dimensioned for a speed of 200km/h and is electrified at. The Ulvin tunnel passes under part of the Morskogen Tunnel, a twin-tubed tunnel which carries the E6.
