These are the hallmarks of the Union Pacific Railroad’s unique GTEL 8500 Horsepower Turbine locomotives. Often called “Big Blows” because of their deafening noise, they roamed the less populated landscape between Council Bluffs, IA and Ogden, UT. 30 three unit sets were built between 1958 and 1961 and all were retired by the early 1970s.
