After cooling their heels for a hour at Yamenmiao to cross an eastbound freight and the passenger, QJ 6984 and 6891 got underway again with a long westbound freight. After a short downhill run to the river bridge, the pair faced 50 km of solid climb to the summit between Chaganhada and Gulumanhan. Judging by their vigorous start from Yamenmiao, they were up for the challenge.
