Abstract: An apparatus for sorting and separating discrete articles such as railroad track material according to shape and size, including an oscillating conveyor, a plurality of spaced parallel bars extending longitudinally along a trough of a sorting end of the conveyor and having leading edges projecting beyond an edge of the trough so that a separating zone is defined, means positioned a spaced distance from the separating zone for receiving a first group of material from the top surface of the parallel bars, and means positioned beneath the separating zone for receiving a second group of smaller-sized material after it falls over the trough edge. The apparatus of the invention also preferably include a hopper, a feeder positioned adjacent the hopper whereby flow of material from the hopper to the oscillating conveyor is regulated, a belt conveyor for transporting the first group of material away from the first receiving means, and an elevating conveyor adjacent the belt conveyor.
