Here is what ScaleTrains.com say about this model:


Just for giggles we put the ScaleTrains GEVO on the test track to get some sound measurements. We were very pleased to find that the preset levels for the various sounds are at less than half of max, and in some cases closer to only a third of max. Compared to the GTEL turbine whine of 76-78dB, the GEVO at idle is well below 60dB which is probably quieter than your car sitting at idle. When the engine ramps up to speed, it only peaks at about 62-64dB which is a "conversation level" in a quiet car. Even at speed with F2, which turns on both the horn and bell, it still doesn't exceed 68dB, and that is at 2 feet instead of the 3 feet test distance I used for all the GTEL tests. The 10dB difference between the GEVO and the GTEL is the equivalent of 8X the amount of amplifier power. (Every 3db is double the power)

Prototype History: The Evolution Series is a line of diesel locomotives built by GE Transportation Systems, initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.

The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by industry publication Trains Magazine. It was the only locomotive introduced after 1972 to be included in that list. The Evolution Series, mainly the ES44DC, ES44AC, and ET44AC, are some of the best-selling and most successful freight locomotives in United States history, far surpassing the output of Electro-Motive Diesel.

ES44AC
The ES44AC (Evolution Series, 4400 HP, AC traction) replaced the AC4400CW model in the General Electric catalogue. The GE Evolution Series ES44AC locomotive represents an incredible combination of power, performance and efficiency. Originally designed to meet US EPA Tier 2 emissions, the ES44AC locomotive utilizes a 12-cylinder GE Evolution Series engine with 4-stroke combustion technology to maintain horsepower, reduce emissions, and lower fuel consumption compared to GE’s predecessor 16-cylinder FDL engine. From 2005 to 2015, the ES44AC became GE’s standard North American locomotive and a compelling platform for others worldwide.

ES44AH (C45AH)
The "H" in ES44AH stands for "heavy", which is in reference to a combination of subsystems that produce high levels of tractive effort at low speeds. UP's "AH" types are similar to CSXT's, except for their Hi-Ad trucks, and are designated C45AH's by Union Pacific.

ES44C4
The ES44C4 (Evolution Series, 4400 HP, AC traction, 4 powered axles) was introduced in 2009. While similar to the ES44AC, the ES44C4 has two traction motors per truck, instead of the conventional three such as on the ES44AC. The center axle of each truck is unpowered, giving an A1A-A1A wheel arrangement. BNSF Railway is the launch customer for this model.

ES44DC
The ES44DC (Evolution Series, 4400 HP, DC traction) replaced the Dash 9-44CW model in the General Electric catalogue. Primary users are BNSF Railway, CSX Transportation, and Canadian National Railway.

ET44AC
The ET44AC (Evolution Series Tier 4, 4400 HP, AC traction) replaces the ES44AC model. The GE Evolution Series ET44AC locomotive meets the U.S. Environmental Protection Agency’s (EPA) stringent Tier 4 emission standards without the use of any aftertreatment, enabling railroads to gain significant savings through urea infrastructure cost avoidance and reduced operational costs. Part of the Ecomagination-certified Evolution Series, the ET44AC locomotive is designed to meet Tier 4 emissions standards by reducing emissions by 70% below Tier 3 requirements. GE Transportation has invested $600M in the Evolution Series since its introduction in 2005 and is the first supplier of Tier 4 locomotives for Class 1 railroads.

Road Name History: The Union Pacific Railroad (reporting mark UP) is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and employs 42,600 people. It is also one of the world's largest transportation companies.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.

Brand/Importer Information: ScaleTrains.com, Inc. is an upstart HO and N Scale model manufacturer that was founded by a team with more than 125 years of accumulated experience in the model railroad hobby and industry.

ScaleTrains is specifically focused on the tiny details in the printing and quality of the construction. The four friends who founded the company are all avid modelers themselves. Their factory is located in Tennessee. Unlike most other companies, they offer a range of different levels of complexity in their offerings so as to be able to provide products for both the budget-conscious collector as well as the detail-focused model enthusiast without compromising on quality for either.

They range covers the following, by increasing level of detailing:

1. Operator™ trains are built for modelers who enjoy running high-quality, realistic trains at an affordable price. Designed from builder’s drawings and photographs, Operator models have fewer factory-applied parts and simplified printing. For added versatility, super-detail parts are available separately.
2. The Rivet Counter™ line strives to create the most accurately detailed models imaginable. The real-world counterpart is meticulously researched to ensure prototype fidelity. Each model features numerous factory applied parts including roadname and road number specific details whenever possible.
3. Museum Quality™ models are historically accurate replicas of the most famous locomotives in North American railroading history. Exhaustive research and a commitment to perfection combine to create the ultimate scale model. Museum Quality trains establish new standards which make them just as legendary as the original.
