  • Patent number: 10711406
    Abstract: A tie having a non-linear keyway under the overlying rail to provide support to restrain lateral and longitudinal movement of the rail. A fastening system to hold rails down on a tie comprises a rail plate that may be fastened to the tie within the keyway. The fasteners are protected to avoid damage in case of a derailment or other adverse conditions. Also disclosed are visual inspection mechanisms to assist with determining whether a fastening system is securely attached to the tie.
    Type: Grant

  • 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.

  • Patent number: 8752773
    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.

  • Patent number: 6350093
    Abstract: An electrically insulated anchor device is described, comprising a rigid elongated metal sleeve including an external surface that leads from an open top end to a bottom end. A longitudinal internal bore is formed within the sleeve with a bore wall spaced from the external surface by a sleeve wall thickness dimension. An electrically insulative polymer insert with an external surface engages the bore wall within the sleeve. The insert further includes a fastener receiving bore defined by a fastener receiving wall spaced from the external insert surface by an insert wall thickness dimension. The sleeve wall thickness dimension is substantially greater than the insert wall thickness dimension.

  • Patent number: 6129288
    Abstract: A railroad crossing panel filler for attachment to a headed support member on a railroad crossing panel slab includes an elongated elastomeric filler body with a slab engaging surface formed along the body. A rail engaging surface is also formed along the filler body opposite the slab engaging surface. An elongated support member head receiving channel is formed within the filler body and extends along the length thereof between the slab engaging surface and the rail engaging surface. An elongated support member receiving slot extending along the length of the filler body and includes a first open end along the slab engaging surface and a second end opening into the enlarged support member head receiving channel. The support member head receiving channel and support member receiving slot are configured to releasably receive a headed panel support member to releasably mount the elastomeric filler body to the panel.
