Thanks again.

The Oct. 10, 1864 raid that "drove the Yankees out" of Rogersville and opened the railroad and telegraph "all the way to Carter's Depot" proved what I stumbled across. That Rogersville would have been the end of the line of CSA railroad travel from Virginia to East Tennessee.
Trains could use the 12 mile spur from Rogersville Jct. to Rogersville to turn engines around to travel back north to Virginia.
