The Evolution locomotive is the most technologically advanced, diesel-electric, heavy-haul locomotive in the world today.
The Wabtec's 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, a Wabtec company 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.
The Wabtec 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 Wabtec Evolution Series engine with 4-stroke combustion technology to maintain horsepower, reduce emissions, and lower fuel consumption compared to Wabtec’s predecessor 16-cylinder FDL engine. From 2005 to 2015, the ES44AC became Wabtec’s standard North American locomotive and a compelling platform for others worldwide.
A heavy-haul locomotive specifically designed for 1,000 mm gauge railways, the Wabtec Evolution Series ES43BBi locomotive is equipped with a powerful 12-cylinder 4500 HP Wabtec Evolution Series engine, a technologically advanced AC traction system with individual axle control, and robust articulated trucks. It is also equipped with a redesigned Air-to-Air system and new extra blowers directly integrated onto the traction motors. The ES43BBi locomotive delivers lower life-cycle costs due to improved fuel efficiency, lower emissions, and reduced parts wear.
The Wabtec Evolution Series ES44ACi locomotive has been engineered to efficiently operate in the hottest climates and very harsh mining environments. Equipped with a turbocharged 12-cylinder Wabtec Evolution Series engine, a high ambient cooling system, and individual axle control technology, the ES44ACi locomotive provides exceptional performance in the extreme climate of Australia. With excellent fuel efficiency and low life-cycle costs, the ES44ACi locomotive helps to enable that your daily operations are efficient and uninterrupted.
