Climbing the grade out of Rossville, the 4501 leads one of TVRM's "Summerville Steam Special" excursions from Chattanooga, TN to Summerville, GA. The route is the former Central of Georgia C-line, now owned by the state of Georgia and operated by the Chattooga & Chickamauga shortline. The green orb sitting atop the running board at about the midpoint of the boiler is some sort of large fruit which fell from a tree and rode around with the engine all day.
