Iore, often stylized IORE, is a class of 34 electric locomotives built by Adtranz and its successor Bombardier Transportation for the Swedish mining company LKAB’s railway division Malmtrafik. The class is a variation of Adtranz’s Octeon modular product platform, thus related to Bombardier’s later TRAXX platform. The locomotives haul iron ore freight trains on the Iron Ore Line and Ofoten Line in Sweden and Norway, respectively. The 8,600-tonne (8,500-long-ton; 9,500-short-ton) 68-car trains are hauled by two single-ended Co′Co′ locomotives, each with a power
