The 630 leads TVRM's "Summerville Steam Special" between Chattanooga, TN and Summerville, GA, on the former Central of Georgia C-line, now operated by shortline Chattooga & Chickamauga. This run was the first time that the 630 had operated on this line since its restoration and was also the first time a TVRM steam excursion had run south of Chickamauga since the summer of 2009, when flooding damaged portions of the line.
