High Quality Content by WIKIPEDIA articles! In the 1990s the Norwegian State Railway had a need for light to medium power freight locomotives; at first the company hired DE 6400 type locomotives (see NS Class 6400) of the type used by the Nederlandse Spoorwegen (NS). This led to an order of twenty similar locomotives, with features similar to the NS Class 6400 and the MaK DE 1002. including the single slightly off centre cab. The locomotives were about 3 m (9 ft 10 in) longer than their predecessors, and were powered by a more powerful Caterpillar Inc. engine (about 300 to 400 kW more powerful). Additionally the electrical transmission system was now sourced from Siemens (the locomotive factory's ultimate owner) rather than an ABB system as had been used previously. The Siemens electrical system utilised gate turn-off thyristor (GTO) semiconductor technology to supply the traction motors, while the auxiliary electrical equipment was powered by a insulated-gate bipolar transistor (IGBT) inverter.
