Abstract
A railroad fastening system that includes a see-thru (transparent or translucent) rail seat assembly which allows for immediate visual feedback to assess whether that a sufficient amount of adhesive material has been applied to a crosstie during the installation of a rail seat assembly on a crosstie to ensure a long-lasting bond and a proper cant, flatness and height of a rail seat assembly.
Claims9
A rail seat assembly, comprising:
- a pad that is at least one of entirely transparent and translucent and includes a main body a first rail having atop surface and a bottom surface extending both longitudinally from a first side of the main body and a uniform width from the first side of the main body to an outer periphery thereof, the first rail being devoid of one or more projections extending from the top surface thereof, and a second rail having a top surface and a bottom surface extending both longitudinally from a second side of the main body and a uniform width from the second side of the main body to an outer periphery thereof, the second rail being devoid of one or more projections extending from the top thereof with the first rail and the second rail, in an assembled state, extending over sides of a crosstie;
- and
- one of an entirely transparent and translucent plate that is independent of the pad, affixable to a top surface of the pad, and includes a plurality of grooves that are spaced from each other.
A method of performing in track rail assembly repair, the method comprising:
- cleaning a rail seat of a crosstie;
- applying an adhesive material to an abraded area of the rail seat;
- placing a rail seat assembly that includes a pad that is at least one of entirely transparent and translucent and includes a main body, a first rail extending both longitudinally from a first side of the main body and a uniform width from a first side of the main body to an outer periphery thereof and a second rail extending both longitudinally from a second side of the main body and a uniform width from a second side of the main body to an outer periphery thereof, the first, rail and the second rail each having a top surface and a. bottom surface with the top surface devoid of one or more projections therefrom with the first rail and the second rail, in an assembled state, over the adhesive material;
- affixing a pad that is at least one of entirely transparent and translucent, and includes a plurality of grooves that are spaced from each other to the pad;
- and
- applying pressure to the rail seat assembly to adjust the height, cant and flatness of the assembly.
