ADtranz DE-AC33C

The DE-AC33C, known as the Blue Tiger, is a high powered diesel-electric locomotive developed by ADtranz in association with General Electric. General Electric supplied the diesel engines and the electrical transmission, which used IGBT-based inverters driving AC traction motors, and AdTranz built the rest of the locomotive in Kassel. The prototype was unveiled in 1996, with an expected axle load of 18 tonnes and about 2,500 kilowatts that became 21 tonnes in practice for the German locomotives. The German production models had a mass of 126 tonnes and an engine power of 2,430 kilowatts. Pakistan Railways placed the first orders in the late 1990s for broad gauge units with a 16-cylinder engine, Malaysia took twenty metre gauge locomotives in 2003 and 2004 as its Class 26, and ten standard gauge units were built in Germany for leasing. Bombardier took over AdTranz in 2001 and showed the locomotive at InnoTrans in 2002, but by 2009 it no longer listed the class as a production model.
