Oh man, I like that video. It's by Delay In Block Productions and their stuff is first rate. In the frame below, what must be one of the last SOU classic cantilever signal bridges standing and in service can be seen. Just up ahead you can see the junction where the line splits to the right to Saluda and to the left to Old Fort. That's the Biltmore, NC depot to the right.
That is some great camera work!! Top notch! Amazing, this was everyday life at one time, and this happened thousands of times everyday, all over North America!!
