Join the Trains magazine team for an amazing journey as we follow one of the largest steam locomotives ever built on the first part of its journey from a museum piece to an operating locomotive. Watch with us as the Union Pacific steam crew moves Big Boy No. 4014 from California’s Rail Giants Train Museum across the West, over iconic Cajon Pass and fabled Sherman Hill. Watch the crew move 4-8-8-4 inside the shop in Cheyenne, Wyo., for the first time. It’s the only complete video of Big Boy on the road to restoration.

Approximate running time: 90 minutes.
