In 2002, GE released the first of a new series of locomotives that would replace the popular Dash-9 series. The ES44DC and ES44AC, often called GEVOs for General Electric Evolution series, were designed to meet the stricter diesel locomotive emissions standards imposed by the EPA Tier II regulations. To meet the new standards, GE developed the 12-cylinder GEVO 12 engine. Both the bore and stroke were increased to produce the same 4400 horsepower as the older 7FDL16 16-cylinder engine. The new engine drives an alternator producing AC current that is rectified to DC current. On the ES44DC, this powers the traction motors. On the ES44AC, the DC current is “chopped” back into AC to power the traction motors. The two models share a common 73’ 2” frame and external appearance.

The ES44DC and ES44AC external details have changed with almost every year’s new orders. These models are of the early version from 2005 and 2006 and include the nose door on the left side, two closely spaced dynamic brake vents, X-panels on the electrical cabinet with a capacitor box on the walkway just behind it, side grab irons on the long hood and flush-mounted top radiator grilles and radiator compartment doors.

This new Genesis Early Version GEVO ES44AC model is based on the excellent Tower 55 tooling, but has been vastly improved and updated to provide the most detailed and accurate HO Scale version of the plastic GEVO on the market today. Available in both DCC Ready and DCC w/Sound versions, this is the perfect compliment to the Genesis SD70ACe & SD70M2 locomotives on your modern layout. And just like the new Genesis EMD GP38-2's, each model is tailored to the real life prototype for each railroad. Many individual detail parts are applied to each unit and vary from road to road. The first release of this new model includes multiple road numbers for three popular roads.

Cabs are individually detailed and feature road specific details such as GPS units, air conditioners & side windows.
	Roof access panels are separately applied pieces to give proper appearance and overhang, just like the actual units.
Underbodies are fully detailed with correct trucks, underbody piping and individual air tanks, as per each prototype.
