“Big Boy” by Wilbur Craig
Wilbur's 6 foot long steam locomotive, "Big Boy," is on exhibition at the Cheyenne, Wyoming Depot Museum. It has approximately 8,000 parts and was created from photographs of the real locomotive sitting in the Cheyenne railroad yard. Many parts move and it can be taken apart and reassembled.
