C40-8W Diesel Locomotive

Prototype Information

GE introduced the C40-8W in 1988 as an upgraded version of its Dash 8 line, designed for heavy mainline freight service. The locomotive featured a 3,800-horsepower 7FDL-16 engine and a wide-nose “North American” safety cab, improving crew protection and comfort. Advanced microprocessor controls enhanced traction, fuel efficiency, and diagnostics compared with earlier models.

Railroads such as Norfolk Southern, CSX, and Union Pacific embraced the C40-8W for its combination of power, reliability, and modern crew amenities. Its wide-nose design and modular body panels made it immediately recognizable on North American rails.

The C40-8W became a key link in GE’s evolution of high-horsepower locomotives, bridging the gap between the Dash 8 and the later Dash 9 and Evolution Series.
