Hartwell Railorad-georgia

This is a very interesting shortline that runs from taccoa,ga to elberton,ga with a spur to hartwell.... the spur to hartwell appears to the ROW for one of THE original rail lines, the rail is so light its next to nothing, it is less than 80lbs.. the rail line is like a roller coaster, it was clearly built before machinery did the job... the 'shops' are open air.. this is by far one of the most interesting shortlines I have ever run into..
anyway, I am trying to find out more about the hartwell.. the the actual hartwell rail company does own other lines in the area too..but I'm talking about the original hartwell railroad..
