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 are considered to be one of the most powerful locomotives and 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 were scheduled to be delivered from 2013 to 2014.
