BigBoy 4012

Presently, BigBoy #4012 resides at the SteamTown National Historical Site in Scranton PA. The following is an archive geared specifically at those special few involved in the construction of a scale model of the Union Pacific Bigboy. These photos represent a small grouping of my total collection of detailed BigBoy photos usable in the construction of a scale model. If you are interested in more photos of higher quality prints of those in this section of the BigBoy Information Center, please feel free to Email me at Unitah@aol.com.
