  • Method of installing interface pad on concrete ties
    Patent number: 10458071
    Abstract: An interface pad for a concrete tie includes a resilient contact pad to cushion the tie from any overlying parts in a railway application, such as panels in a grade crossing or rails in a turnout. 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 and methods to correctly secure such an interface pad to a concrete railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the tie.
