In a railroad publicity photo set in forbidding Western scenery, Union Pacific's Challenger, train 108, rounds a curve with EMD E8A 930 in the lead. The photo was taken in 1953, shortly before the reinstatement of the Challenger streamliner in January 1954 after a World War II discontinuance. Note that the train number has been airbrushed onto the locomotive's number board, so this is likely the new Challenger equipment running as an extra for pre-operational publicity, or possibly it is a different train posing as the Challenger. This 930, delivered in 1950, was the second UP E unit to bear this number; an earlier 930, an E7A, was renumbered to 989 in 1948. The single track rules out this scene as being anywhere east of Ogden, Utah, on the Challenger's route.
