No I have not used the editor yet so it is all a new experience for me, should be fun
It should be interesting as there are not many TM maps and I have not played it much ( I keep loosing
I was just looking at the PA map from Mr Scott's revised and it looks good. I was thinking Harrisburg to Pittsburgh because I wanted to do a mini campaign not the whole thing in one scenario but may change my mind and make it one with "chapters" so when you finish one goal you are presented with the next. I do agree with your thoughts and I have the Centenial book the first 100 years which is about 4" thick and tells the story about the making of the PRR from 1846 to 1946, lots so good stuff in there.
About the web site for maps, I have never used it before and will have a look see. I would be interested in seeing your map. I assume you need me email address and if I'll provide it in a PM. I want as large a map as I can get and still have room for some of the smaller towns/communities (New York to Pittsburgh). If I am successful at this then maybe a map of Ohio to Indianna so I can do the "Pennsylvanis Lines" from Pittsburgh to Chicago and St Louis... just a though and ambitious.
