Grade crossing interface pad

摘要

The invention relates to an interface pad comprising a stiffener supporting a resilient pad to cushion the panels in a grade crossing between and around the rails from impact with the underlying ties and to prevent the panels from moving. The pad may be flat or a cupped shape and may be of varying size to accommodate varying tie widths. The invention further comprises means to securely fasten such an interface pad to a railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the rails or panels in the grade crossing.

主权项

1. An interface pad for a tie in a railway grade crossing comprising a rail and at least one concrete grade crossing panel, each supported by said tie, said interface pad having an underside and an upper side opposed to said underside, and further comprising:
a stiffener; a resilient pad stiffened by said stiffener; and at least one fastener passageway through said stiffener and said resilient pad to accommodate a fastener to secure said interface pad to said tie with said underside located on said tie and said upper side facing said panel; wherein said passageway is shaped to allow said fastener to fit substantially below said upper side of said resilient pad, out of contact with said panel.
