ADtranz DE-AC33C
The Blue Tiger (manufacturer designation: DE-AC33C) is a type of high powered diesel-electric locomotive developed by ADtranz in association with General Electric. History and design. The prototype was unveiled in 1996. Initially the axle load was expected to be a light and the power at ~. In practice, the German locomotives had an axle load of (which is normal for this type of diesel locomotive). General Electric supplied diesel engines and electrical transmission system (which used IGBT-based inverters driving AC traction motors). The rest of the locomotive was built by AdTranz in Kassel. For  the Pakistani export models a 16-cylinder engine was used. Bombardier took over AdTranz in 2001, subsequently the Blue Tiger locomotive was shown at InnoTrans in 2002 with a view to European orders. The German production models had a mass of (axle load ) and an engine power of . As of 2009, the class is no longer listed as a production model by Bombardier; GE also lists the family as a former production type. For the European market, Bombardier produces the less powerful diesel variants of the TRAXX family, whilst GE offers variants of its Evolution series for export. Operators. Pakistan . The first orders for the locomotives came from Pakistan Railways in the late 1990s. The locomotives were being built to a gauge of and powered by a 16-cylinder engine of instead of the 12-cylinder engine used in the prototype and other production models. The first ten were shipped out, the remainder assembled under license in Pakistan. Pakistan Locomotive Series Start From 6001 to 6030. Malaysia. Twenty locomotives were built to gauge in 2003–2004 for KTM. They were designated as "Class 26" (Numbers: 26101 – 26120). All the locomotives were named after capes in Malaysia. In the first decade of  operations the locomotives proved more reliable than the Malaysian Class 29 locomotives bought at around the same time. Germany. 10 Locomotives were built to gauge with a view to leasing or orders. Various companies have used the locomotives. Initially "Karsdorfer Eisenbahngesellschaft GmbH" (KEG) was to use 8 units, but went bankrupt in 2005. In 2006, the distribution was: Models. A working scale model of this locomotive has been produced by the Slovenian company Mehano in N, TT and HO scale.
