Abstract
A pair of mud dispersement devices are deployed beneath a railroad tie and upon ballast material supporting the tie. Each device includes a flat elongated structure for underlying a half of the railroad tie and resting upon the ballast material supporting the tie. The elongated structure has opposite inner and outer ends and opposite top and bottom surfaces and defines a wedge-shaped cavity below the bottom surface which increases in height proceeding from the inner end of the elongated structure to the outer end thereof. A plurality of support elements are mounted on the top surface of the elongated structure and project upwardly therefrom for contacting the railroad tie to transmit a load produced by rolling stock moving on the railroad track downwardly from the railroad tie to the inclined plate. A plurality of ballast collection and mud dispersion elements are mounted on a bottom surface of the inclined plate and project downwardly therefrom into the ballast material for maintaining the ballast material in the load bearing area beneath the railroad tie while permitting the passage of mud from the load bearing area toward and beyond the outer end of the side members in response to the downward load transmitted from the railroad tie to the inclined plate.
