Abstract: In one aspect of the present disclosure, a side bearing is provided for supporting a body of a rail car. The side bearing includes a base for being mounted to a truck of the rail car, a support configured to contact the body of the rail car and move along a vertical axis relative to the base with movement of the body, and at least one resilient foam member configured to deform with movement of the support. The side bearing further includes at least one friction damping member configured to be urged in a direction transverse to the vertical axis against the base by the support and resist movement of the support relative to the base.

Abstract: Railyard management system for managing, assembling, disassembling and validating train consists and monitoring railcars in the railyard. The system provides for the collection of data and the movement of data from lower processing levels to higher processing levels, where an inference engine draws inferences regarding the current state of railcars and train consists within the railyard. The inferences can be based on characteristics of a transmission signal received at their respective railcars, said railcars forming a train consist. The system can be used to track the location and orientation of railcars in the railyard and to validate order and orientation of assets in a train consist based on the characteristics of the transmission signal at said railcars.

Abstract: In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.

Abstract: A rail car truck bolster wear plate surface connects to a wear plate using two fasteners of different length. The first fastener passes through an upper opening and an upper channel into a first recess where it can be tightened against a first engaging surface. The second fastener is longer than the first fastener and passes through a lower opening and lower channel into a second recess adjacent to the first recess. The surfaces of the first and second recesses form a series of ribs in the upper end surface between the wear plate surface and the longitudinal centerline of the bolster.

Abstract: A railway car hatch cover assembly is provided comprising an outer hatch cover, and a gasket retainer. A venting gasket is provided comprised of mesh venting material, and a hydrophobic coating is applied to the mesh venting material. The venting gasket forms a seal with the outer hatch cover and the hatch ring coaming. The hydrophobic coating is usually applied to an outer surface of the mesh venting material. The mesh venting material allows the passage of air therethrough, while providing a barrier to the passage of dirt or similar debris.

Abstract: An improved polymeric knuckle pin with at least one indented area that elastomer rings rest in. The indented area is strategically placed in an area on the shaft of the pin where the coupler-knuckle connection exerts impact, force, and stress on the pin. The elastomer rings in the indented area provide cushion to the pin from the impact, force, and stress, allow the pin to avoid hard contact with the coupler and knuckle, distribute the loads exerted by the coupler and knuckle more evenly, realign the coupler and knuckle positions, and protect the pin itself from surface cuts and scratches. The elastomer rings on the shaft of the pin improve the life of both the coupler-knuckle assembly and the pin.
