Here we are at Marion tunnel, the northern portal (36.688458, -81.980895), a little over 219 miles from Elkhorn City KY on the CSX. This is the final tunnel on the line. It’s pretty much all flat land from here to Spartanburg SC. Marion tunnel is 1,073′ long and the lintel date is 1913, which means it’s probably original to the tunnel. That’s a CSX locomotive coming out of the tunnel, heading up into The Loops. Although this ends my project to document all the tunnels on this CSX line, there’s more to come.
