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 output of 5,400 kW (7,200 hp). Each operates with 600 kilonewtons (130,000 pounds-force) tractive effort and has a maximum speed of 80 km/h (50 mph). Delivery of the first series of 18 locomotives was made from 2000 to 2004, and they replaced some of the aging Dm3 and El 15 units. In 2007, eight more vehicles (4 double units) were ordered, with production to be completed by 2011, by which time, another four double units were ordered. These units are scheduled to be delivered from 2013 to 2014.
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.
