QJ 6828 and QJ 6356 dragged a coal train up the final kilometre to Shangdian just before sundown on 15 December 2000. The top of the climb was in sight but, for the crew, that wasn't necessarily the good news it might appear. The draughty cab of a coasting QJ wasn't the most comfortable place to be on the long downhill run into the freezing night that lay ahead.
