The Ofoten Line and the Iron Ore Line are two railroad lines which were built to allow iron ore to be hauled from the LKAB's mines in Kiruna, Svappavaara and Malmberget in Sweden to Luleå on the Baltic Sea in Sweden and to Narvik on the Norwegian Sea in Norway. Historically, these lines were operated by the Norwegian State Railways (NSB) in Norway and the Swedish State Railways (SJ) in Sweden, but in 1996 the operations, but not the infrastructure, were transferred to the new company Malmtrafik i Kiruna (MTAB), a joint venture between LKAB, NSB and SJ, and its Norwegian subsidiary Malmtrafikk (MTAS). At the time, the line was using El 15 and Dm3 locomotives.
