Union Pacific Steamer no. 3985: The 4-6-6-4 Challenger, Articulated Steam Locomotive, 1992
Union Pacific Steamer no. 3985: The 4-6-6-4 Challenger, 1992! Union Pacific articulated steam locomotive, number 3985, was built in July 1943 as a 4-6-6-4 Challenger-class behemoth for hauling fast freight long distances. The railroad owned only one class of steam locomotive larger than the Challenger, the 4-8-8-4 Big Boy. Number 3985 was retired by the Union Pacific in 1962. Nevertheless, it was restored to operating condition for excursion service in 1981, as part of the railroad's public relations effort. In August 1992, UP 3985 pulled the "Pacific Limited," east from San Jose, California, to its home in Cheyenne, Wyoming. On August 2nd, the steam engine and its matching train of vintage Union Pacific streamliner passenger cars left Salt Lake City, Utah, on home rails. This was an era when historic locomotives were not required to carry along "protection power," a modern diesel locomotive behind the steamer. The Challenger used its own tractive effort to hustle its sizable excursion train across the western landscape that made the Overland Route famous.
