Union Pacific Steam Shop Tour and Big Boy 4014 Restoration

Tour of the Union Pacific Steam Shop in Cheyenne, WY with a steam shop employee answering questions. Union Pacific has two of the largest steam locomotives made in the world and one (4014) is currently undergoing restoration to operational condition. Each of it's 16 driving wheels is as tall as a man. Video is a really interesting overview of the Mechanical Engineering that is behind the operation of these locomotives.
