TVRM’s passenger trains run on the historic route which includes Missionary Ridge Tunnel, completed in 1858 and on the National Register of Historic Places. The tunnel is the primary reason TVRM runs on the three-mile section of the former Southern Railway. As railroad equipment grew too large to pass through and the single-track tunnel became a traffic jam for an other wise double-track railroad, Southern Railway abandoned the three mile portion of the line and built a new section around the end of Missionary Ridge, avoiding the tunnel altogether.
