Tennessee Valley Railroad & Museum
Tennessee Valley Railroad & Museum Missionary Ridge Local. One of the highlights of the trip is riding through Missionary Ridge Tunnel, a.k.a. the Chattanooga, Harrison, Georgetown, & Charleston Railroad Tunnel, especially noted for it's uniqueness as a horseshoe tunnel. The bottom of the tunnel actually pinches in so that as it rises, the sides curve out before curving back in to form the roof.
