I just purchased some rail maintence maps from a guy on ebay, and I wanted to pass on what I think is a good deal. He has a bunch of maps and charts that tell crossings, signal protection, type of rail, age of rail, bridges, location of sidings, and much much more. For entire divisions too! While they are very simple, I like them in combination with other road maps and such.
He also has some operating manuals and such. And if you don’t see anything that you like try shooting him an email as he has a bunch of unlisted stuff.
And lastly he sent me a buck off his maps that is free game for any of you that order…
