The Røros Line (Norwegian: Rørosbanen) is a 383 kilometres (238 mi) long railway line in Norway running between the towns of Hamar and Støren via Elverum and Røros. It connects to the Dovre Line at Hamar to Oslo and at Støren to Trondheim. The Røros Line is Norway's second longest stretch of unelectrified railway, the longest being the Nordland Line. The line is owned by the Norwegian National Rail Administration.
The Røros Line follows the Østerdalen valley, running alongside the river Glomma for much of the way. In terms of the Norwegian railway system the Røros Line is a secondary route between Oslo and Trondheim, the primary route between those two places being by way of the Dovre Line.
As well as being connected to the Dovre Line, the line also has connections to the Meråker Line (at Trondheim) and the Solør Line (at Elverum). The summit of the line, at Harborg, is 670 metres (2,200 ft) above sea level–a fairly low elevation for a Norwegian main line.
Today, passenger trains on the Røros Line are operated exclusively by small diesel multiple units of the types Class 92 and Class 93 operated by the Norwegian State Railways.
