The Røros Line (Norwegian: Rørosbanen) is a 383-kilometer (238 mi) railway line which runs through the districts of Hedmarken, Østerdalen, and Gauldalen in Innlandet and Trøndelag, Norway. The line branches off from the Dovre Line at Hamar Station and runs a more easterly route to Støren Station, where the two lines meet again. The Røros Line also intersects with the Solør Line at Elverum Station. The single track, standard gauge line lacks electrification and only has centralized traffic control south of Røros Station. SJ Norge operate regional passenger trains. In addition the line is used by freight trains hauling lumber and wood chippings.
The first parts of the line was the Hamar–Grundset Line and the Trondhjem–Støren Line, which opened on 23 June 1862 and 5 August 1964, respectively. To save costs, the lines were built with narrow gauge, thus making it the first locomotive-hauled 1,067 mm (3 ft 6 in) line in Norway. The Grundset–Aamot Line extension to Rena Station was opened on 19 October 1871. The connecting line onwards to Støren opened on 13 October 1877. The 1880 completion of the Dovre Line to Hamar allowed a continuous train service linking Oslo and Trondheim, albeit with a break-of-gauge in Hamar.
