Introduced in 2012, General Electric’s ET44 GEVO Series represents the latest in diesel-electric locomotive technology. Nearly every Class I railroad in the United States and Canada roster the GE Tier 4 GEVO.

Our Rivet Counter series model renders the numerous variations of engine cab rooflines, antennas, dynamic brakes, trucks, and more. We’ve also incorporated LED lighting effects including front, rear, and side walkway lights; ground lights (when applicable); printed and lighted number boards; and ditch lights.

Introduced in 2012, General Electric’s ET44 GEVO Series represents the latest in diesel-electric locomotive technology. The GE Tier 4 GEVO is designed to meet stringent Environmental Protection Agency (EPA) emissions regulations.

The EPA “Tier” emissions standards are a series, or Tiers, of allowable emissions levels based upon a locomotives’ date of manufacture. The highest and most stringent tier level, Tier 4, sets maximum allowable NOx and hydrocarbon emissions levels for locomotives built for use in the United States from 2015 onward.

While similar in appearance to previous GE ES44 GEVO designs, the Tier 4 models featured a longer frame compared to their predecessors. This allows for a larger radiator “cab” (GE refers to the various sections of the long hood as “cabs”), and a “hump” over the engine cab for advanced exhaust treatment equipment.

Initially, a boxy housing filled the entire roofline on the blue-painted field test/demonstrator units. Due to changes in treatment equipment and clearance issues, the “hump” would decrease in size and shape into a boxy compartment around the exhaust on initial production units. This culminated in an angled compartment surrounding the exhaust manifold on locomotives produced since 2016.

Despite boxier engine cab rooflines and a radically styled radiator cab, the basic Tier 4 design shares a family appearance with GE safety cab-equipped units going back to the DASH-9s of the 1990s. It even includes the same 12-cylinder GEVo-12 series prime mover and 4,400hp as its predecessor model.

The Tier 4 units have proven to be popular with nearly all major U.S. and Canadian railroads. While GE has settled on a basic carbody design to keep production costs down, there are notable variations and detail differences due to customer specifications including antennas, dynamic brakes, trucks, and more.

With over 1,000 units built, the ET44 is a common site across North American railroads.
