Topped Off And Ready For Service
Title:  Topped Off And Ready For Service
Description:  4005 rests in the engine terminal at Cheyenne. The Big Boy has just topped off on coal, and will have its tender filled with water for another westbound journey. The tender of each Big Boy was a behemoth of its own. Each one measured just over 47 feet long, and had a capacity for 56,000 pounds of coal and 24,000 gallons of water. A stoker engine and mechanical lubrication system were also located in the tender, directly behind the cab under the coal bunker. Despite this massive size, stops would still have to be made to complete the arduous journey over the Wasatch range. Obtained from Union Pacific Steam: Big Boy Portraits (Bush, Ehernberger)

UP 4005 Before The Accident
Title:  UP 4005 Before The Accident
Description:  UP 4005 has little time before its accident the next year. On April 27 1953, the unit took a bad switch at Red Desert at 50 mph, flipping the locomotive, and piling the first 18 cars of the 62 car train in a 70 heap. The tender was pushed into the cab of the flipped engine, killing the engineer and fireman, and crushing the brakeman. Escaping steam shot 100 feet into the air, preventing the nearby section gang from approaching the roiling engine. The brakeman would be extracted from his cramped position between a seat and the side of the cab after 10 hours, but would later succumb to his wounds. Four of the first 18 cars had been full of hogs, and most of these were killed on impact, although some did survive, and escaped into the Wyoming desert. After the wreck, the mangled Big Boy was stored in the yard in Cheyenne until it was rebuilt. Exact date unknown. Obtained from Union Pacific Steam: Big Boy Portraits (Bush, Ehernberger)

Light Engine 4005
Title:  Light Engine 4005
Description:  In mid-November 1956, 4005 trundles through the yard in Laramie. The coaling tower looms over the cab of the engine. This tower, along with most of the other engine faclities in Laramie, is long gone today. 4005, however, would survive the end of steam on the UP. The unit was stored as of November 30, 1958, and was marked as unserviceable in 1960. Ten years would pass before the engine would donated to the Forney Museum in Denver, Colorado in 1970.
