Originally built by my father in 2004-ish, this building is one of my dad's biggest creations. I modified it and brought it up to my specifications... okay, I whinged it from looking at the model about two years ago. I took some liberties, (and made some mistakes) with the original model. For example: the first version had a smaller smokestack, (diameter wise) and a different Railroad loading dock. I also changed the roof to be removable to allow access to the inside.
