QJ 1722 and QJ 1494 worked a short freight south from Longgou on the bitterly cold morning of 2 January 1990. The white 'object' below the smokebox door of QJ 1722 is actually a cloud of leaking steam surrounding the loco's water pump. At least it hasn't obscured half the loco like QJ 1494's cylinder leak. With mile after mile of 1 in 50 gradients ahead, it was just as well that the train wasn't too heavy.
