A car shaker for use particularly on a rail type hopper car. At least one closure and preferably a plurality thereof is provided to preclude or minimize the amount of dust which results from a dust carrying cargo being discharged. The at least one closure rests on the top of the hopper car to preclude coal dust entering the atmosphere. The car shaker is further provided with an aspiration system to draw away cargo dust which has been wetted by water sprays from a manifold carried on the closures.
