For the first time in several years, some of Sandaoling's locos were clean enough to glint. JS.8167, the shiniest of them all, approached Ba'erzhan with a lightly loaded train shortly before sunset on 2 December 2015.
Trains loading on this line generally took an eternity to fill, so it was a surprise when JS.8167 set off, with most of the train still empty, around half an hour after arriving .
