  • Powered by GE Transportation’s 12 cylinder diesel engine, the Evolution Series Engine produces the same 4,400 HP as its 16 cylinder predecessor  with less fuel. This 45 degree, 12 cylinder, 4 stroke, turbocharged engine provides efficiency, fewer emissions and extended overhaul intervals. The engine also uses enhanced cooling and higher strength materials that dramatically improve reliability and allow for future increases in power and efficiency.

    The Evolution Series Locomotive meets the most stringent emissions standards including U.S. EPA Tier 3 and EU IIIa. The Evolution Series Engine also is offered in a 16 cylinder configuration that delivers 6,000 HP.

    The current Evolution Series Locomotive is the result of a 10 year, $400 million investment by GE Transportation. Introduced in 2005, it is an incredible combination of power, performance and efficiency. These locomotives provide measurably higher reliability and lower life-cycle costs than previous GE Transportation models.

    They also apply GE Transportation’s proprietary AC propulsion technology and control equipment that are more reliable and provide superior performance. The Evolution Series Locomotive is so powerful that one 12 cylinder locomotive can pull the equivalent of 170 Boeing†† 747 jetliners. Built on a forward-looking and flexible global platform, the Evolution Series Locomotive is designed to meet global market needs and comply with current and future emissions standards. Today, more than 8,000 Evolution Series Locomotives are operating in 10 countries.

    A product of ecomagination

    GE Transportation was mindful of the environment when it developed the Evolution Series Locomotive. Not only was it essential to build a powerful, reliable and efficient locomotive, controlling its environmental impact also was critical.

    The results are remarkable: The Evolution Series Locomotive represents one of GE’s most prominent ecomagination products. Ecomagination is GE’s commitment to build innovative products that maximize environmental and economic impact. Products with GE’s ecomagination designation undergo a rigorous process to prove they measurably help customers’ performance and bottom lines while simultaneously improving their environmental performance.

    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 model utilizes a 12-cylinder GE Evolution Series engine which leverages 4-stroke combustion technology to maintain horsepower, lower emissions and 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 platform for others worldwide.

    GE Evolution Series ET44C4 locomotiveis an industry breakthrough, delivering a modern and efficient alternative to the DC-powered locomotive models. Compared to GEDC EVOs and Dash 9 locomotives, the ET44C4 model powers only 4 axles rather than 6 while maintaining the performance of a DC locomotive, allowing railroads to enjoy savings both in locomotive price (compared to the ET44A locomotive model) and operating cost (fewer traction motors to maintain). One of the ET44C4 locomotive technology breakthroughs is a unique feature, the Dynamic Weight Management (DWM) System, that continuously monitors traction performance. Whenever additional adhesion is required, the DWM system automatically transfers some of the weight from an idler axle to the AC-powered axles without operator assistance.

Air-to-air cooling

The locomotive incorporates GE Transportation’s most advanced cooling system in rail transport. In addition to a standard radiator and fan configuration, locomotives powered by the Evolution Series Engine use an advanced air-to-air cooling system for engine combustion air to enhance performance while lowering emissions.

AC individual-axle traction control

Evolution Series Locomotives deliver GE Transportation’s industry-leading AC individual-axle traction-control technology that enables greater hauling power by significantly reducing slippage on startups, inclines and during suboptimal track conditions. This unique technology ensures optimum performance, less wasted energy and substantially reduces maintenance costs and associated down time during the locomotive’s life compared to older DC and other AC technology traction systems.

Dynamic braking

In addition to air brakes, the Evolution Series Locomotive is equipped with dynamic braking technology that reduces wheel and brake shoe wear by an estimated 20 to 40%, depending on usage. Delivering up to 117,000 lbs. of (AC) braking effort, the locomotive uses field-tested grids and blowers from GE Transportation’s AC 4400 and Dash 9 locomotives. The braking grids are also completely isolated for greater reliability and simplified maintenance.

Computer-controlled architecture

The locomotive features sophisticated operator controls that improve diagnostics and simplify operation. The consolidated control architecture of the Evolution Series Locomotive makes it easier to upgrade software and download data. “Smart” displays eliminate several add-on black boxes in favor of a computer and display combination that enhances both reliability and operator ergonomics.
