In 2002, GE introduced the “Evolution Series” of locomotives. Better known as GEVo or ES44, this series has become the best-selling line of diesel locomotives of all time with production nearing 8,000 units.

Our Rivet Counter series model renders the numerous variations of cabs, dynamic brakes, doors, grilles, trucks, etc. We’ve also incorporated LED lighting effects including front, rear, and side walkway lights; ground lights; printed and lighted number boards; and ditch lights.

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.

Iowa Interstate (reporting mark: IAIS) is a Class II Regional Railroad that operates in the states of Illinois, Iowa, and Nebraska. The railroad began operations in 1984 on 580 miles of former Rock Island track. Grain products are the primary commodity shipped on the IAIS but the railroad is also known for hauling coal, frac sand, metals, ethanol, and intermodal traffic. In 1985, the railroad was able to access Chicago via trackage rights over CSX and Metra rails.

In the early years, IAIS rostered a mixture of ancient ALCOs and rebuilt first-generation EMD locomotives. As the company became more profitable and restructured, they refined their locomotive roster by replacing older units with reliable GP and SD38 series models. In the late 2000s, however, they turned to GE by ordering a series of 14 ES44 GEVO locomotives. These units were built to CSX specifications with early radial or “steerable” trucks. The majority of these units were painted in the company’s stunning black, yellow, and red livery with large IAIS logos on the GE safety cab.

The first locomotives in the series arrived on the property in November of 2008. Upon delivery, Iowa Interstate added rear ditch lights since there aren’t many places to turn locomotives on its system. After ditch lights were installed, the GEVOs were placed into revenue freight service. They quickly became fan favorites and were joined by the rest of the series as individual units were delivered over the next year. In December of 2009, road number 513 was painted in a special Rock Island “Rocket” heritage paint scheme at Mid-America Car, Inc. near Kansas City, Missouri. It was delivered to Iowa Interstate in January of 2010.

In 2014, IAIS purchased three (3) additional “Tier 4 Credit” ES44 GEVOs that were built in Fort Worth, Texas by GE Transportation successor, Wabtec. Visually, they are identical to the original order from 2008, aside from road number 516, which was painted in a special red and yellow 30th Anniversary paint scheme. All of Iowa Interstate’s ES44 GEVOs are similar to Norfolk Southern’s units in that they have both front and rear flashing ditch lights. With limited turning facilities along their mainline, the rear ditch lights allow IAIS trains to operate at track speed.
