The East Tennessee & Western North Carolina RR had a not-well-known (and hardly ever photographed) branch running eats out of Elizabethton north of the Watauga River, toward Buladeen.
A local who wrote/photographed/drew for the Elizabethton Star took some shots and sketches of the line before going to England to cover WW2 for the Associated Press.
I’m currently working together his photos and sketches and writings into a book I’ll probably publish through Blurb.com
