The Yanzhou Coal Railway's operations were centred on Dadongzheng yard, around 5 km west of Zoucheng. On the afternoon of 1 January 2005, QJ 6814 got a long loaded coal train rolling out of the east end of the yard towards Yanzhou. Although the landscape is fairly flat, trains were long and heavy and the locos had their work cut out on even the slightest gradients. Most trains we saw consisted of 50 C62 or C64 wagons grossing around 4200 tons when fully loaded.
