Southern 4501 at Missionary Ridge Tunnel, Chattanooga, TN

September 10, 2017 – A gentle cool breeze and birds can be heard in the surrounding trees until till the shrill of a steam whistle and sounds of an approaching locomotive breaks the quietness as it approaches the west end of Missionary Ridge Tunnel.

Next thing you know, it has covered the 900 feet and then Southern Railway steam locomotive 4501 breaks out of the east side of the tunnel as it heads to Tennessee Valley Railroad Museum’s East Chattanooga station and shops, with a train load of passengers, during the 2017 Railfest.

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.
