Good evening from australia. I have a interest in track plans and diagram books. When i visited the usa back in 2001 i bought the 4 vol set of diagrams that up had. I hope it might be possible to find the same sort of information here.
Andrew, Welcome Aboard. You will find our forum fairly well organized. All of the prototype historical information can be found in the Historical side of the forum. Most of what you are looking for will be found under Historical, Operations. But don't limit yourself to that area; there is a lot more interesting stuff to be found.
