SD40-2 Diesel Locomotive

Prototype Information

The EMD/GMD SD40-2 is a 3,000-horsepower (2,200 kW) C-C diesel–electric locomotive built by EMD from 1972 to 1989.

The SD40-2 was introduced in January 1972 as part of EMD’s Dash 2 series, competing against the GE U30C. Although higher-horsepower locomotives were available, including EMD’s own SD45-2, the reliability and versatility of the 3,000-horsepower (2,200 kW) SD40-2 made it one of the best-selling models in EMD’s history, edged out only by the GP9, and was the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X.
