 The rail yard also contained a "coal wharf", a coal storage facility which could load an engine's tender in under 30 seconds, and two gigantic water spouts which could fill an engine's water tank from above in less than a minute.The tracks throughout the rail yard were lined with numerous inspection pits (where workers in a pit low the tracks could inspect the lower and underside portions of an engine quickly) and ash pits (pits where engines could quickly dump their coal ash for later retrieval and disposal).The Ivy City rail yard also contained a coal-powered steam generating plant.
