Erwin to Spartanburg This program explores CSX's old Clinchfield line from Erwin, Tennessee, to Spartanburg, South Carolina. You'll travel the line from the south end of Erwin Yard to the middle of the loops at Bob's Gap to view heavy coal and freight trains, coal trains tackling the southbound grade at the Nolichucky River with tail-end helper service, the picturesque roll down the southern slope of the Blue Ridge Mountains, and more. Color, 1 hour. #0RV2102
