The Union Pacific Railroad used steam locomotives in it rich history. I found this link and video fascinating. I can imagine some of the characters in my novels riding trains like these.
"Departure of Union Pacific Steam Locomotive No. 844 from the Great Overland Station in Topeka, Kansas. Easter Sunday, April 4, 2010. Steam Locomotive No. 844 is the last steam locomotive built for Union Pacific Railroad. It was delivered in 1944. A high-speed passenger engine, it pulled such widely known trains as the Overland Limited, Los Angeles Limited, Portland Rose and Challenger.
Hailed as Union Pacific's "Living Legend," the engine is widely known among railroad enthusiasts for its excursion runs, especially over Union Pacific's fabled crossing of Sherman Hill between Cheyenne and Laramie, Wyoming."
