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
