The EMD Model 40 was a two-axle diesel-electric locomotive built by Electro-Motive Corporation (EMC), and its corporate successor, General Motors' Electro-Motive Division (EMD) between August 1940 and April 1943. Nicknamed ''"critters"'', eleven examples of this locomotive were built. Powered by twin General Motors Detroit Diesel 6-71 diesel engines, which produce a combined . It's drivetrain is unusual because the two diesel engines are used to drive the electric DC generator from both sides, one with clockwise rotation and the other with counter-clockwise rotation.
