The Sierra #3 steam locomotive, built in 1891 by Rogers Locomotive, is completely torn down and rebuilt. The locomotive is likely the most recognized steam loco in the world, having been seen my millions of people during appearances in more than 100 movies and TV shows over several decades of use, including "High Noon," "The Great Race," "Back to the Future III," "Petticoat Junction," and "Little House on the Prairie."
