The Chattanooga sub would be a great thing to do with the history it's had and another CSX route would be awesome. Trying to get this done so I can show the Cowan museum what yall did and get more people to discover the Chattanooga sub. Please if ya can I'd be glad to help in anyway I can. Anyways. The Chattanooga sub goes from Nashville to Chattanooga, going thru smyrna,Murfreesboro,bell buckle,wartrace,Tullahoma,decherd,cowan,sheerwood,anderson,Stevenson,bridgeport,tunnelhill,then Chattanooga. It's 137 miles long and it would be something nice to see.
