EMD Locomotives

Electro-Motive Diesel, Inc., also referred to as “EMD”, designs, manufactures and sells diesel-electric locomotives and diesel power engines. The company is owned by Caterpillar through its wholly owned subsidiary Progress Rail Services Corporation.[2] EMD offers an extensive range of locomotive products in the rail industry.[3]

Electro-Motive Diesel, Inc. traces its roots to the Electro-Motive Engineering Corporation, founded in 1922. In 1930, General Motors Corporation purchased the Winton Engine Co. and Winton’s primary customer of gasoline engines, the Electro-Motive Company (a manufacturer of gasoline-electric self-propelled rail cars), combining the two to form GM’s Electro-Motive Division (EMD) on January 1, 1941.
