This Would Be Freaking Awesome

The Union Pacific Railroad is attempting to restore and run a 4-8-8-4 Big Boy locomotive next year.  Seeing live steam locomotives run is a rare but fabulous spectacle, but most of what is still running is WAY smaller than this locomotive they are restoring.  I am not sure most people have a sense of scale for these beasts.  I chose the picture below because it has people in them for scale.
