  • Patent number: 7374109
    Abstract: A rail cushion assembly including a resilient rail pad for placement against the lower surface of a railroad rail, and an underlying abrasion plate for placement against a railroad tie. The rail pad includes a pair of slots that extend through opposite end sloping edge panels that are adjacent to the lower surface of the rail pad. The abrasion plate is a flat, sheet-like component that has a generally similar shape as that of the rail pad but includes a pair of outwardly-extending connection tabs, one at each of a pair of opposite edge surfaces. The connection tabs of the abrasion plate are received in respective slots of the rail pad to provide the rail cushion assembly in ready-to-use form and without requiring on-site assembly of the components.
