WOW Dave! This is very interesting,I did not think any of the Siverton Railroad grade exsisted! I also thought(see thats whatya get fer thinkin!) the grade was lower than the current road, it seems it would make railroad sense to be lower in the valley? Also I see after the loop in Chattanooga the grade is above the current road which I thought(here we go again!) crossed the road(lower) and then swung around and up? I was wondering this because U see a grade from the highway plus on the Sat view, or is what I'm seeing remaines of the old toll road?
Thanks.
