The GP 7 locomotive is a diesel-electric locomotive that was designed and manufactured by the Electro-Motive Division (EMD) of General Motors between 1949 and 1954. It has a 16-cylinder, 1500 horsepower engine and was a popular choice for railroads across North America due to its reliability and versatility. The locomotive is 56 feet long and weighs 246,000 pounds.
