The ES44ACi locomotive is a heavy-haul locomotive specifically designed for the South American market. Equipped with a 16-cylinder GE FDL 16 engine, the AC44i can deliver up to 4,500 HP while helping to keep fuel consumption and emissions to a minimum.
The ES44ACi locomotive with AC individual-axle traction-control technology combined with High Adhesion Trucks allows customers to haul heavier loads by significantly reducing slipping on start-ups, inclines and suboptimal track conditions. The Heavy Haul AC propulsion technology maximize the traction effort and achieves higher levels of power. The AC44i also features high-performance dynamic braking, which can dissipate up to 5900 HP, reducing car-wheel and car-brake shoe wear, while also improving down-hill operation safety.
