Union Pacific 844 is the only steam locomotive in the country that has never been retired from service. The final steamer delivered to UP, the 844 was the last of 10 FEF-3 Class (Four-Eight-Four; Third Series) locos built in 1944 by the American Locomotive Works of Schenectady NY. After a relatively short 15 years in revenue service, the 844 was selected by the railroad to continue in excursion service in 1960, a second career which has now lasted 56 years and counting.
Here, the 844 is seen running between Denver and Cheyenne on an excursion back in August 1978, wearing the number 8444 to avoid conflict with a UP diesel of the same number. The diesel 844 impostor has long-since been retired allowing the 844 to resume its original and rightful identity
