DBAG Class 128

The DBAG Class 128, registered by Deutsche Bahn as 128 001 and known to its builder AEG Schienenfahrzeuge as the 12X, is a single experimental high-performance electric locomotive built in 1994. AEG developed it in the early 1990s in anticipation of a large German tender for universal locomotives. It carried power electronics with new types of semiconductors and water cooling, a new final drive concept, a new bogie concept and protruding wind flaps for better aerodynamics that gave it a distinctive look. It served as a testbed and test locomotive until 2010, passing with its maker through the successor companies Adtranz and Bombardier Transportation, and its modular design was the basis of the DBAG Class 145 freight locomotive and, in the end, of Bombardier's TRAXX locomotive platform.
