Was running a few errands today and stopped by Devine Jct. in Columbia, SC to see what was happening. Caught two trains in fifteen minutes. CSX was due as well, but rain was encroaching and I packed it in. Local P75 is a turn on its way west to Monetta, SC. The 6927 is a former C&NW SD-60. Those tiny signals are interesting, but I don't know much about them. There are several switches in the area that can be actuated by radio and this is probably one. Train 18D is in from Spartanburg on its way to the Port of Charleston. The 4382 is a GE AC44C6M. The local as seen above used the track in the foreground.
