What an awesome experience. I have seen the Big Boy before, but never experienced anything like it coming out of that tunnel. The amount of air 4014 pushed out in front of it combined with the sound was truly incredible. Pictures to follow soon.

A 1.2-million-pound steam legend crossing one of the largest concrete railroad viaducts ever built. Nicholson, Pennsylvania delivered an unforgettable scene today.
