SY 1344 was the pilot at Beichang washery on 26 February 2006 and was photographed pulling a long rake of CNR wagons through the loader.
Although it might be thought that a single pass under the hopper would be enough, each rake was worked backwards and forwards several times. The vast majority of coal was loaded on the first pass with much smaller quantities added on further passes to ensure that every wagon contained exactly the right amount.
