Renowned as one of the largest steam locomotives ever built the 4-8-8-4 Big Boy on the Union Pacific is featured in this vintage program. Also included is the other Union Pacific articulated type, the 4-6-6-4 Challengers. Made from 8mm and 16mm films of various photographers we see a good variety of action, including some doubleheaded freights, and some surprises. Copyright 2008 Greg Scholl Video Productions
