Today, GE introduced its latest Evolution Series locomotive, which slashes fuel consumption by a whopping 17 percent when compared to North America’s aging fleet of DC-powered engines — and cuts emissions by 70%. It’s not only good news for railroad operators and the environment; it’s a win for Pennsylvania — as the new Model ES44C4 is manufactured at GE’s plants in Erie and Grove City.Today, GE introduced its latest Evolution Series locomotive, which slashes fuel consumption by a whopping 17 percent when compared to North America’s aging fleet of DC-powered engines — and cuts emissions by 70%.

New kid in town: Six hundred of GE’s latest locomotives can displace up to 800 older locomotives, translating to an annual reduction of more than 70 million gallons of fuel -– the equivalent of taking 115,000 cars off the road for a year. The overall annual emissions reduction from this displacement is estimated to be 48,000 tons of nitrous oxide; 1,500 tons of particulate matter; and 1.0 million tons of carbon dioxide, a major greenhouse gas.
Historically, DC technology, in which diesel fuel is used to generate direct current, has been the lower initial-cost option for heavy-haul freight applications. However, DC traction motors are found to be susceptible to reliability issues that require significant down time for repair as well as frequent maintenance for brush replacement and extensive cleaning. GE’s new AC motors, while also powered by diesel fuel, are not only more fuel efficient and cleaner, they have fewer parts to maintain and eliminate the electrical problems that hamper DC motors. As a result, they are easier to install and will spend more time on the rails instead of in the maintenance shop for repairs.
