The Wabtec Evolution Series ES43BBi locomotive is a heavy-haul locomotive specifically designed for 1,000 mm gauge railways and is equipped with a powerful 12-cylinder 4500 HP Evolution Series engine and eight powered axles designed to operate in extreme environments.
Along with the service-proven GEVO12 engine, Wabtec has added to the ES43BBi a technologically advanced AC-traction system with individual axle control and robust articulated trucks. The ES43BBi is also equipped with a redesigned Air-to-Air system and extra blowers directly integrated onto the traction motors. This locomotive comes with lower lifecycle costs due to improved fuel efficiency, lower emissions, and reduced parts wear.
