Towards the end of 2004, impending EPA regulations forced GE and EMD, the nation's two major locomotive builders, to redesign their respective line-ups. GE's demo unit was tested on the AP&W's Pittsburg Division in western Pennsylvania, passing through Hillsdale.
The new locomotive is here! GE 2005 is the new prototype demonstrator for the forthcomming Evolution Series. A GE rep brags about his company's latest model to the Hillsdale gang while waiting for the operating crew.
GE 2005 is a 4400hp engine; officially an ES44AC (Evolution Series, 4400hp, AC traction motors).
Built to meet tougher emissions standards, the new engine also boasts improved fuel economy as well -it has a 12-cylinder engine instead of the 16-cylinder of its predecessor, the AC4400.
The new, larger radiator not only provides improved engine cooling, but reduced emissions as well thanks to its split air/water cooling systems which provide cooler intake air to the engine. The smaller engine allows for the needed increase in cooling capacity.
