September 9, 2017 – Southern Railway steam locomotive 630 heads into the west end of Missionary Ridge Tunnel with a loaded passenger train during the 2017 Railfest at Tennessee Valley Railroad Museum, as it heads for the station at East Chattanooga, Tennessee. By the way, I love long lenses!!!
Completed in 1858 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 otherwise 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.
The museum restored rails through the tunnel in 1971 and continues to use the pre-Civil War Tunnel on a daily basis.
