In the decade they ran, UP's 8500-series Gas Turbine Electric Locomotives earned two nicknames: the "Super Fleet" as they were the largest, most powerful locomotives ever employed by the railroad. More often they were called "Big Blows" due to the deafening roar of their engines. Used primarily between Ogden, Utah and Green River, Wyoming, where the tough grades of the Wasatch Mountains required UP's sturdiest power, these monsters could log up to 10,000 miles a month hauling heavy mixed freight and coal trains. Their prime mover was the most powerful ever used in a locomotive. Video Rails take you back to the 1960s with dramatic footage of UP's Turbines at work. You'll see them being serviced, watered, sanded, and fueled and then follow an assortment of trains past Weber and Echo Canyons and be treated to thrilling scenes along this scenic route before they reach their eastern boundary at Green River.
