    The EMD SD40-2: A Workhorse of the Rails

    The EMD SD40-2 is a diesel-electric locomotive that has become an iconic workhorse in the rail industry. Produced by the Electro-Motive Division (EMD) of General Motors, the SD40-2 was introduced in January 1972 as part of EMD's Dash 2 series. Production continued until October 1989, making it one of the longest-running locomotive models in EMD's history.

    Prime Mover and Specifications: The SD40-2 is powered by the EMD 16-645E3 prime mover, a turbocharged V16 diesel engine. This engine delivers 3,000 horsepower (2,200 kW), providing the locomotive with the power needed for heavy freight operations.

    Production Numbers: A total of 3,982 SD40-2 units were produced during its production run. This impressive number made the SD40-2 one of the best-selling locomotive models in EMD's history, second only to the GP9.
