A dust control device for preventing dust and debris from escaping into the atmosphere during the process of loading rail cars with grain or other granular commodities/products. The dust control device generally includes a dust hood that is moveably supported on a pair of stationary elongated support rails via wheels. The support rails are attached to a delivery spout of an elevator and extend over the path of travel of a rail car to be loaded. An elongated pivotable engagement arm connected to the dust hood extends downwardly into the path of the rail car and is engaged as the car passes beneath the dust hood. The dust hood moves with the rail car from a ready position to an operational position in close proximity to the delivery spout to capture the dust and debris generated during the loading process. When the rail car disengages from the engagement arm, the dust hood returns to the ready position automatically and without a power source under the force exerted by a spring-biased positioning assembly.
