I see nobody commented on your video. Tough crowd here sometimes Mike. I was down there in October for a Summerville trip with 4501. I see you did one of the $50.00 cab rides with 630. I think the 2-8-0 is more impressive on a train as it has to work a little harder. We wanted to do the local, but the 4501 trips took priority. The track next to the train that drops down is the Chattanooga Belt Railway that they take to go off-line from TVRM trackage. Looks like you had a good time. For those not into SG steam that much, the two Southern RWY steam engines are nice looking, and have a place to run on a 50-mile line.
Check out their website for schedule of trips.
