PROTOTYPE AND BACKGROUND INFO:

The EMD 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 and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the 3,000-horsepower SD40-2 made it the best-selling model in EMD's history and 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.

Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, with production continuing for railroads in Canada until 1988, Mexico until February 1986, and Brazil until October 1989.

SD40-2s are still quite usable nearly fifty years after the first SD40 was made, and many SD40s and locomotives from the pre-Dash-2 series (GP/SD 40s, 39s and 38s, and even some SD45s) have been updated to Dash-2 specifications, possibly including downgrading from 20-645E to 16-645E engines, including, certainly, Dash-2 electrical controls, although the pre-Dash-2 frames cannot accommodate the somewhat similar HTC truck in the space allocated to the Flexicoil C truck (the frame is not long enough). Most SD40-2s which remain in service have by now been rebuilt "in-kind" for another 30 to 40 years of service, although a few (under 30) have been rebuilt to incorporate a 12-cylinder EFI-equipped 710G engine.
