NS GP40-2 #3068 shoves a short train of boxcars and the NW water tender across the Chickamauga Creek bridge along Tennesee Valley Railroad Museum's mainline in Chattanooga, Tennessee. Freight and NS power is a rarity at this location, and the NW canteen is even more rare for a TVRM movement. Photo by Casey Thomason. For more information about Norfolk Southern, visit www.nscorp.com
