The Loops: Quinn Knob

As the CSX heads down the Blue Ridge, it makes the first Loop, curling around to come back to about 100′ away from the tangent that leads into it (but 132′ lower).  Coming out of 2nd Washburn, about 1/4 mile away to the south, lies Quinn Knob tunnel, 545′ long.  It carries a 1912 date on this south lintel at 35.841637, -82.041630.  It’s on a slight bend, leading to 3rd Washburn, which we’ll get to shortly.  Then we’ll take a break and gaze at four tunnels down on Norris Lake.  Ever hear of the Knoxville, Cumberland Gap & Louisville Railroad?  It was involved in the breaching of Cumberland Gap for the mighty steel rails.  More later.
