Performance on track

Since its introduction more than a decade ago, GE’s AC4400 locomotive has been proving its reliability and productivity in heavy-haul freight applications. Today, thousands of AC4400 units are operating dependably around the world.

Engine

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.

Traction System

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.

Control Capabilities

Microprocessor controls in the AC4400 integrate a range of operator interfaces for improved productivity.
