CSX - Sensabaugh Tunnel
Posted September 22, 2019, by Rachel (rachellcannon [at] hotmail [dot] com)

I was presently surprised to find anything online about this particular tunnel. There is so much folklore surrounding the tunnel below this one and it seems like nobody knows that this one exists (which is fine). A few friends and I climbed to the railroad tracks and found this tunnel about 10 years ago and I always found it fascinating. It's beautiful and undisturbed.
