Braswell was also the location of the only tunnel on the Southern Railway (now Norfolk Southern) Chattanooga to Atlanta main line. The tunnel was bypassed in 1979 by cutting through Braswell mountain slightly to the east. The tunnel is still there, but is overgrown with vegetation and is a safety hazard due to snake infestation. Another nearby tunnel, at Divide, is currently used by bicyclists and joggers on the "Silver Comet Rail Trail".
