Union Pacific Locomotive #26 was among the largest locomotives ever built and was powerful enough to pull 735 fully loaded freight cars, creating a train seven miles long. It used a turbine engine like a jet airplane to power electric generators that turned the wheels, and locomotives of this type were called "BIG BLOWS" because they made a deafening noise like a jet airplane flying by. Locomotive #26 traveled over 1 million miles hauling heavy freight between Council Bluffs, Iowa and Ogden, Utah, and it is one of two surviving "BIG BLOWS" on public display. Built in 1961, it weighed 849,248 pounds, measured 179 feet long including the fuel tender, had an 8500-horsepower gas turbine, carried 24,384 gallons of diesel, could reach a top speed of 65 miles per hour, and was retired on February 28, 1970. Its tender for the turbine was a retrofitted steam locomotive tender filled with Bunker C oil, a residual or heavy fuel oil used frequently in the past.
