Mobile railway asset monitoring apparatus and methods
In one aspect, a mobile railway asset monitoring apparatus is provided that includes a sensor configured to produce a signal indicative of a rotation of a wheelset of a mobile railway asset. The apparatus further includes a processor to receive data corresponding to a ground speed of the mobile railway asset. The processor is operably coupled to the sensor, the processor configured to estimate a running dimension of the wheelset based at least in part on the rotation of the wheelset and the ground speed of the mobile railway asset. The processor is configured to determine at least one parameter of the mobile railway asset based at least in part on the running dimension of the wheelset.
SYSTEM AND METHOD FOR AUTOMATIC WHEEL DIAMETER MEASUREMENT AND CALIBRATION
A system for automatic wheel diameter measurement and calibration comprises one or more sensing device(s) configured to sense rotation of a wheel and provide rotation data of the wheel, a positioning system configured to provide positioning data of a vehicle, a database including milepost and distance data, and a controller configured to automatically calculate a wheel diameter and a wheel diameter inaccuracy based on the rotation data, the positioning data, and a distance between a start point and an end point extracted from the database, during operation of the vehicle. Further, an associated method and non-transitory computer readable medium are described.

Encoder bearing hub assembly for rail vehicles
The present disclosure generally relates to a bearing hub assembly of a rail guide wheel apparatus for a rail vehicle. The bearing hub assembly may couple rail wheels to the rail guide wheel apparatus. The rail guide wheel apparatus may be included on a Hi-Rail vehicle or any other vehicle configured to travel along railroad tracks. The bearing hub assembly includes a sensor that is integrally mounted within the bearing hub assembly. The sensor collects information associated with rotation of the rail wheels. Information collected by the sensor may be used to determine a speed, direction, location, and/or distance traveled of the rail vehicle.

Rail pressure adjustment assembly and system for rail vehicles
A rail vehicle including a wheel assembly having wheels configured to traverse rails of a railroad track, a controller having a processor in communication with the wheel assembly, and a non-transitory computer readable medium, disposed on the vehicle, and containing instructions, which, cause the following steps in real-time as the vehicle traverses the rails: determine a rail pressure of the wheels on the rails, determine a degree of curvature of the rails as the vehicle moves along the railroad track, determine a minimum rail pressure of the wheels on the rails based on the degree of curvature, determine if the rail pressure is equal to or greater than the minimum rail pressure and adjust the rail pressure of the wheels on the rails to be the minimum rail pressure when the rail pressure is less than the minimum rail pressure to maintain stability of the vehicle on the railroad track.
