Jeff, the various and sundry RR historical societies web-sites are a great help, or the historical societies that don't have web-sites (getting fewer everyday) are of help for a nominal charge. Often the hardest part is finding the histoical society that now has the "Armpit and Eastern", because it was absorbed by the "Sweatshirt and Southern", then the "Southern and Boondock", and is now listed with the Conrail society. Make sense? Google is not always our best freind on these things. Getting to the right site can be down-right frustrating.
