Starting in 1985, Seaboard System began routing some coal and empty trains via NS trackage rights from Appalachia, Va to Frisco, TN (until a new bridge at Big Stone Gap could be completed). This required trains to either turn entirely on the wye (which was a major traffic tie-up), or swap ends, with the head end power going to the rear, and the pushers to the head end. Today, however, the three lead SD50s have stumped their toe going through a tight connection between the two roads. The lead truck of SD50 8520 is on the ground as employees from both roads attempt to get her back on the rails the old tried and true method--with wooden wedges, a lot of profanity, sweat and know-how. The SD40-2 looking on is one of two rear end helpers.
