The EMD SD40-2 is a 3,000-horsepower C-C diesel-electric locomotive built by EMD from 1972 to 1989. It was introduced 1972 as part of EMD’s Dash 2 series to compete 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 top-selling model in EMD’s history and the standard of the industry for several decades. The SD40-2 was an improvement over the SD40 because of ah modular electronic control systems.
The 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. The last SD40-2 delivered to a US railroad was built in 1984. Many SD40-2s remain in service.
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. Most SD40-2s which remain in service have by now been rebuilt “in-kind” for another 30 to 40 years of service.
