You can tell from previous images that Union Pacific 844 is a very large steam locomotive owned by Union Pacific Railroad. But until you get down beside it, you can’t appreciate how large it really is. The main wheels are as large as a person. I remember standing beside it wondering how much each of these wheels must have weighed, then how much power the locomotive must create just to turn those wheels, much less pull the train.
