The trains hauled by Iore-class locomotives are 68 cars long and weigh . From Riksgränsen on the national border to the Port of Narvik, the trains use only a fifth of the power they regenerate. The regenerated energy is sufficient to power the empty trains back up to the national border. Although the trains and hopper cars are all owned by LKAB, the line is owned by the Swedish Transport Administration and the Norwegian National Rail Administration. The Ore and Ofoten Lines are also used by passenger and container trains.
