We have had the pleasure of visiting the museums and parks containing static displays of the amazing Union Pacific "Big Boy" steam locomotives. Recently, we were able to view #4012 at Steamtown, Scranton, Pennsylvania.

In addition to "museum" examples, since the re-start of #4014, we've managed to see this remarkable machine in action.

For #4014, see:
