The largest diesel locomotive ever built is the Union Pacific “Big Boy” 4014. The “Big Boy” is a type of high-speed, long-distance, heavy-duty steam locomotive developed for use in freight service. It was built by the American Locomotive Company (ALCO) in 1941 and was used to haul massive loads across the western United States. The “Big Boy” locomotives were specifically designed for the steep mountain grades of the Wasatch Range, and were the largest steam locomotives ever built.
The “Big Boy” locomotives were 132 feet long and weighed over 1.2 million pounds when fully loaded. They were capable of reaching speeds of up to 80 miles per hour, and were equipped with a massive 7,000 horsepower engine. The “Big Boys” were used primarily to haul heavy freight trains, and were known for their incredible pulling power and reliability.
