A wayside railway sensor package is provided to detect railway wheels for the purposes of assessing the speed and direction of a train in order to align any measured characteristic on said moving train with the proper vehicle. The stand-alone package is easily installed in the web of the rail using standard tools. When used in combination with recent processing techniques, the package can be used to replace one or more components or subsystems on all common wayside detectors while also providing enhanced capabilities and improved reliability. The package also contains sensors that provide data used for assessing additional rail, wheel, and vehicle conditions directly.

Wayside railway sensor package and method for application

A system is provided for tracking the wheel bearing temperatures of a train and selecting those that are statistically determined to be abnormally high, while eliminating from consideration, or otherwise categorizing those high temperature readings which are the result of other anomalous and non-anomalous conditions. The system determines the overall distribution of the bearing temperatures for both sides of a train at each wayside location. The bearing temperatures are ranked for comparison with the overall train distribution. Outliers are detected and characterized based on temperature patterns and previous history.
