The EMD SW8 is a type of diesel-electric switcher locomotive built by Electro-Motive Division (EMD) from 1950 to 1954. It features an 800-horsepower engine and is designed for switching duties in rail yards and industrial areas. The SW8 is known for its compact size and maneuverability, making it ideal for moving freight cars in tight spaces. With a total production of 1,000 units, the EMD SW8 has been widely used by various railroads across North America. Its robust design and reliability have contributed to its longevity, with many units still in operation today, serving both freight and museum railroads.
