Powering the locomotive model is GE’s 7FDL™ engine, a medium-speed turbo-diesel engine designed to meet the unique demands of locomotive duty. Electronic fuel injection and split cooling promote fuel savings, reduce emissions and lower maintenance costs.
Computer-controlled inverters—one per axle—regulate the AC traction motors. This individual axle control assures maximum tractive effort, independent of wheel diameter variation, offering reliable adhesion in all-weather conditions.
Microprocessor controls in the AC4400 integrate a range of operator interfaces for improved productivity.
