Abstract
A three-batch method for the precision loading of coal into the individual railroad cars of a moving train, and a loadout system implementing the method. For each railcar, three successive batches are made up and discharged from a single weigh bin. The loadout rate of a single-batch system is approached, but at a significantly reduced facility cost. The first batch is large enough to fill the front of the railcar and to establish a "plugged flow condition," allowing the second batch to be made up and discharged while maintaining a constant load profile in the railcar. After the weigh bin is emptied of the second batch, the third batch is made up and discharged. The third batch is made up with greater precision than the first and second batches.
