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.

A truck assembly for a rail vehicle includes at least one side frame including at least one lightener hole. At least one strain gage is disposed within the lightener hole(s). The strain gage(s) is configured to detect forces exerted into or onto the truck assembly. A method of detecting forces exerted into or onto a truck assembly of a rail vehicle includes disposing at least one strain gage within at least one lightener hole of at least one side frame of a truck assembly of the rail vehicle, and detecting the forces by the strain gage(s).

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.
A method for manufacturing a ring includes clamping a first region of a metal sheet against a mandrel, and, while the first region of the metal sheet is clamped against the mandrel, bending the metal sheet around the mandrel to join opposite end faces of the metal sheet and form the ring shaped to the mandrel. A system for manufacturing a ring from a metal sheet includes (a) a mandrel having a ring-shaped surface, (b) a clamp facing the ring-shaped surface and configured to clamp a first region of a metal sheet to the mandrel, and (c) a plurality of dies configured to bend the metal sheet around the mandrel, while the clamp clamps the first region to the mandrel, to join opposite end faces of the metal sheet and form a ring shaped to the ring-shaped surface.
A truck assembly is configured to travel along a track having rails, and includes a first side frame, a second side frame, and a bolster extending between the first side frame and the second side frame. One or more of the first side frame, the second frame, or the bolster includes at least a portion formed as an I-beam that includes a web having a first end and a second end opposite from the first end, a first flange extending from the first end of the web, and a second flange extending from the second end of the web. A thickness of the web increases away from a first neutral axis towards the first flange and the second flange.

SYSTEM AND METHOD FOR BUILDING AND MANAGING A TRAIN CONSIST
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.
