The EMD F7 is a diesel-electric locomotive built by the Electro-Motive Division of General Motors from 1949 to 1961. It is part of the F series and is known for its distinctive streamlined design and powerful performance. The F7 was primarily used for freight and passenger services, featuring a 1,500 horsepower engine that allowed it to haul heavy loads efficiently. With its robust construction and reliability, the EMD F7 became a popular choice among many North American railroads. Over 2,300 units were produced, making it one of the most successful locomotives of its time. Today, many F7s are preserved in museums and used in heritage rail operations.
