The Dovre Line () is a Norwegian railway line with three slightly different lines which all lead to the historic city of Trondheim. Definition Dovre Line is the 484 km main line between Eidsvoll and Trondheim, used by Jernbaneverket since 2008. Dovre Line is also the current name of the 548 km main line of the Norwegian railway system (Jernbaneverket) between Oslo and Trondheim, used when referring to the long-distance passenger trains. Dovre Line was the name of the 209 km main line between Dombås and Trondheim until 2008. The most inclusive of these meanings of Dovre Line thus includes the other two. To complicate the pattern even more, the first use of the Dovre Line was on the section between Dombås and Støren, completed in 1921. When this last section of the new standard gauge main line between Oslo and Trondheim via Lillehammer and Dombås was opened in 1921, the originally 49 km long narrow gauge section between Støren and Trondheim was made the northern part of the new Dovre Line. When talking about construction of railways in Norway, Dovre Line is the 158,1 km long Dombås - Støren section. Sections of the most inclusive use of Dovre Line (Dovrebanen) General description and short history The section south of Eidsvoll was until 1998 Norway's first public railway, Hovedbanen, from 1854, 68 km long. The present line between Oslo and Eidsvoll is the 4 km shorter Gardermoen Line, the only high-speed line in the country. Hovedbanen is still in service for freight trains (and local commuters to Dal), but is not considered as a part of Dovre Line. The entire line from Oslo to Trondheim is 548 km today. It is a more heavily traveled line than the older Røros Line and electrification was completed 1 November 1970. Between 1935 and 1958, the Dovre Line was served by some of Norway's largest steam locomotives, the 2-8-4 NSB Class 49 "Dovregubben" ("Dovre Giant"). Compared to the Røros Line, the Dovre Line takes a more westerly course running through the town of Lillehammer and over the mountainous stretches of Dovre, before merging with the Røros Line again at Støren. There is one branch line, the Rauma Line which leaves the Dovre Line at Dombås. To avoid the fairly regular river flooding on the railway line along the river Gaula, the Gulfoss Tunnel was completed in 1918 in the Hovin area of Melhus
