Contemporary Steam Locomotives

This view shows the sheer size of the 3985 more clearly. The Challenger locomotive is roughly twice as large as a Soo Line Pacific, for comparison to my favorite railroad. Also visible behind the train is the Union Pacific's special excursion equipment. The UP maintains a full passenger consist in their yellow and grey colors, along with the 3985, Northern 844, and DDA40X 6936 (a rare double-diesel type locomotive, with eight wheels on each truck). If necessary, the 3985 could still pull a freight train from her home base of Cheyenne, WY, but mostly today she pulls these sort of special passenger trains. (Quite impressively, in my opinion).
