JS 5495 and JS 5688 rolled down the bank from Dayangcha towards Hunjiang with a westbound freight on 28 January 1991. It was the passengers that tended to be double headed on this line, not the freights. This was a bit surprising as there was a long climb for westbound trains, which tended to be more heavily loaded than eastbounds, to a summit tunnel about 15km to the east of this spot.
