Abstract: A system and method for detecting the operational status of a brake system on a railcar. The system receives from a sensor an indication of the magnitude of a braking force applied by the braking system in response to an instruction to increase or decrease the braking force. It compares the response to possible responses of the braking system in view of the instruction provided. Based on the comparison, the system generates at least one of a message and/or an alert indicating the status of the brake system. Additional sensors, including a pressure sensor on a brake pipe of the railcar, can be added for additional functionality.

Abstract: A system, method and assembly for detecting the operational status of one or more discharge gates on one or more railcars. The system and method monitor parameters that include whether the discharge gate is open or closed, whether the railcar is in motion or not, and whether the railcar is in a location where it is acceptable for the discharge gate to be open. Sensors carry out the monitoring, and the information obtained by monitoring the parameters are used to determine if a notification event has taken place and if so, a notification of such event can be transmitted to a remote receiver. A change in the status of any one of the monitored parameters can trigger the determination of whether a notification event has occurred.

Abstract: A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter, encircles the rotation axis, and is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

Abstract: A rail vehicle with two sideframes and a bolster as the freight car truck has limits on stability. A railway freight car truck having a friction shoe with a constant force device acting directly on the shoe flat surface is provided, such that the friction shoe is forced to remain in contact with the side frame mating vertical surface. The control spring acting on the friction shoe which applies a varying force to the side frame mating surface. The damping of the friction shoe is retained when there is less variable force of friction, which decreases vertical acceleration of the rail vehicle, providing high speed stability for most track conditions.

Abstract: A slinger for a roller bearing seal includes (a) an inner section extending at least in a first direction parallel to a rotation axis of the slinger, encircling the rotation axis and forming a plurality of tabs configured to pressure fit the slinger onto a rotor of a roller bearing seal, (b) an outer section extending at least in the first direction at a greater distance than the inner section from the rotation axis and encircling the rotation axis, and (c) a middle section encircling the rotation axis and spanning between the inner section and the outer section, wherein the inner section, the middle section, and the outer section define respective portions of a single continuous part.

Abstract: An elastomeric pad is provided for use in a railway car truck that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of an axle bearing assembly. An elastomeric pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Contact buttons extend from the top surface and bottom surface of the elastomeric pad and are received in openings in the elastomeric pad. A conductor provides an electrical connection between the contact buttons.

Abstract: Braking systems for railway cars are provided. A braking system defines a longitudinal axis (L), and includes a first brake assembly (52), a second brake assembly (54), and an actuator (80) operable to generate a linear force, the actuator (80) disposed proximate the second brake assembly (54). The braking system further includes a movable rod (90) and a fixed rod (100) extending between the first brake assembly (52) and the second brake assembly (54). In some embodiments, the braking system further includes a dead lever (110) and a slack adjuster (130) disposed proximate the first brake assembly (52), the slack adjuster (130) connected to the first brake assembly (52) and the dead lever (110) and operable to adjust a distance along the longitudinal axis (L) between a reference point of the first brake assembly (52) and a pivot point (116) of the dead lever (110).

Abstract: A knuckle of a coupler of a rail vehicle includes a leading beam having a pulling face, a lateral offset beam extending from the leading beam, a tail extending from the lateral offset beam, an extension wall extending from the lateral offset beam towards an end of the tail, and a tapered lock engagement wall extending from the extension wall to the end of the tail. The tapered lock engagement wall is angled in relation to the extension wall. The tapered lock engagement wall is configured to engage an interior face of a main body of a lock of the coupler. The interior face defines a knuckle-engaging surface that is configured to bear against the tapered lock engagement wall.
