The South Fork Secondary used to serve numerous coal mines in the past. There are only two active mines now, but the "leftovers" from an old mine can be seen here at BLS Paint.
Two blue 80MACs bring up the rear of C90, crossing Paint Creek. There's a third unit on this rear end consist, an NS 80MAC which is obscured by foliage. This is my 1,000th photo on RP.net.
