Three Southern SDs power a southbound freight near Greensboro, NC || February 1971

Late in a very hot day, a loaded coal train rolls over a timber trestle between Duffield and Gate City in far western Virginia. A radio control car with helpers is at work far back in the train.

The mid-train "slaves" on this coal train kicked out after a slack run-in, resulting in a quite a pile up in 1968 on Southern's Appalachia Division.
