PROTOTYPE HISTORY

In 2002, GE released the first GEVo, a new series of locomotives that would replace the AC4400CW and Dash 9-44CW. The first two models were the ES44DC and ES44AC. The ES44C4 followed a few years later.

The new models were designed to meet the stricter diesel locomotive emissions standards imposed by Environmental Protection Agency (EPA) regulations. The EPA “Tier” emissions standards are a series, or Tiers, of allowable emissions levels based upon a locomotive’s date of manufacture. In 2005, Tier 2 took effect followed by Tier 3 in 2010 and Tier 4 took in 2015.

GE developed a new diesel engine, the 12-cylinder GEVO 12, to meet the new emission standards. Both the bore and stroke were increased to produce the same 4,400 horsepower as the older 7FDL16 16-cylinder engine.

The new prime mover drives an alternator producing AC current that is rectified to DC current. On the ES44DC, this powers the traction motors. On the ES44AC and ES44C4, 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 external appearance is similar to the AC4400CW. In fact, the cab on early ES44s is almost identical. In 2009, GE changed the cab and nose, moving the nose door from the left side to the right side and replacing the curve seams with more square seams.

Unlike their predecessors, both the AC and DC versions of the ES44 have the large box behind the cab. The biggest visual difference is the larger “wing” structure over the radiator cab. The thicker radiators and related equipment in the radiator cab work to cool the exhaust, which reduces emissions.

Customer options and design changes have resulted in seven different dynamic brake configurations. The grilles on the sides of the radiator cab have also gone through seven configurations. The most recent units have changed the latches on the engine cab doors to match the ET44 units.

Although EPA Tier 4 standards went into effect in 2015, the ES44-series continue to be built. This is due to the Tier 4 Credits, a complicated system that allows GE to continue to build and various railroads to buy the ES44 based on the number of Tier 4 units built.

After 2 testbed units and 35 pre-production units, over 7,600 additional ES44s have been built. All of the major railroads including BNSF, Canadian National, Canadian Pacific, CSX, Norfolk Southern, and Union Pacific have fleets with 100s of units. Florida East Coast, Ferromex, Iowa Interstate, and Kansas City Southern also operate ES44s. In addition, 131 were built as lease units for Citirail.

The ES44 has become the best-selling diesel locomotive of all time.

RAILROAD HISTORY

Union Pacific rosters over 1,400 Evolution Series locomotives with several different classifications. The ES44s in this run are designated as C45ACCTEs. The reason why Union Pacific uses such a unique classification is that they chose to have some of their ES44AC locomotives equipped with Controlled Tractive Effort software. Simply put, the “CTE” software is used to reduce the tractive effort of the locomotive when it is used as a Distributed Power Unit (DPU) in mixed freight type service.

The higher tractive effort of the AC units when mid-train (or on the rear) can be too high for the lower-tonnage trains. This is not necessarily the case in bulk commodity service though, such as unit coal or grain trains. The UP System Special Instructions cites that: “Units are limited to 110,000 lbs in tractive effort when in CTE mode.”

Though the majority of UP ES44ACs are designated as C45ACCTE, some are simply designated as C45AH because they do not have the controlled tractive effort software. Those with that designation are currently numbered 2520 to 2469, 2740 to 2769, and 8052 to 8267. Coincidentally, UP classifies all of their GE Tier 4 GEVOs as C45AH as well.
