Trafikverket
Although the trains and hopper cars are all owned by LKAB, the Iron Ore Line is owned by the Swedish Transport Administration and the Ofoten Line by Bane NOR. The lines are single track, electrified at and have automatic train protection. The Ore and Ofoten Lines are both also used by passenger and container trains. Malmtrafik's haulage constitutes the majority of train cargo in Norway, measured in tonnes, although not in tonne kilometers.
