PRR:
I have read all of Norwoods books and Dormans books which take me about so far. I thought there had been a book of only Lively pictures published but I don't have it. I also do not have "Beyond the Third Rail" that may include some additional information that I don't have. I am really looking for something that has not been published that would help us get more flavor for the non-rail aspects of Cumbres as well as the rail parts. But either way you comments are a help, everyones are when you are looking for this kind of a needle in a hay stack.
