3985 reborn
Title:  3985 reborn
Description:  UP Challenger 3985 was on static display at Cheyenne, WY for many years. Then some employees got the notion it might run again. Here, in September of 1979, a burro crane has laid panels to the Challenger, the fence has been removed and geep 327 shepherds the locomotive, with prodigious oiling of valve and driving gear, west to Tower "A" for a reverse move back towards the roundhouse where the capable steam crew will embark upon the process of readying the sleek beauty for many years of excursion service.

UP 3985
Title:  UP 3985
Description:  On the second day of excursions with Union Pacific 4-6-6-4 3985, the big Challenger envelops its train with coal smoke (yes, it was still coal fired at this time) as it passes the USS Geneva Work steel plant in Vineyard, Utah, on June 27th, 1982. The excursions, one on the 26th and another on the 27th, operated from Salt Lake City to Provo and return. The steel mill is now gone, and the main line has been downgraded to a branch line.
