Abstract
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.
