A railroad tie cover of a substantially rectangular configuration composed of an elastomer material with or without an optional pad is provided for increasing the resiliency of rail fastening track systems in railroad track beds with and without ballast to prolong the service life of timber and concrete railroad ties. The railroad tie cover has a center and two side portions which utilize a plurality of grooves that are designed to prolong the operational life of wooden and concrete ties by increasing the resiliency of the rail fastening system and in the case of the wooden timber ties prolong the life of the tie by channeling and transporting water and moisture away from the railroad timber tie. The number, depth and disposition of the grooves with or without the pad in the alternative embodiment fosters the circulation of air around the timber tie during the loading and unloading of the track as occurs during train passage. The railroad tie cover is designed to be manufactured and shipped in a flat configuration which is installed as a three dimensional cover at the work site. The rail tie cover can be cut and trimmed at the work site to accommodate varying lengths of wooden rail ties as may be required for special track work.
A railroad tie cover for imparting resiliency to a track system while prolonging the life of a tie comprising a substantially rectangular sheet formed of an elastomer material having an inside surface adapted to contact a portion of the surface of a railroad tie and an outside surface opposite said inside surface said surfaces providing a center portion having one or more grooves to provide a static stiffness in the range of about 5 lbs. to 40 lbs. per millimeter deflection per square inch and a first side and a second side said sides connected to said center portion and adapted to deform so as to orient said inside surface of said first and second sides to an angle of about 90 degrees to said inside surface of said center portion.
