After leaving the Erdi valley via Tunnel 4 the line runs high up along a ledge cut into the south side of the main valley. Much of this section was difficult to photograph but there were a couple of good locations where the line crossed side valleys on high embankments.
This shot shows QJ 7012 and QJ 6274 dragging an eastbound coal train up the hill towards Shangdian on 1 March 2003.
