NS U56 has returned to Appalachia from St. Charles (ex-Southern) with a combination of "commercial" loads and "yellow ball" loads. The crew has set the "commercial" loads off on the main line and shoves the "yellow balls" into Westmoreland Coal's prep facility at Appalachia. Once the "yellow balls" are set off, the crew will shove the "commercials" through Appalachia to the ex-Interstate Railroad's Andover Yard for weighing.
