Abstract: A rail vehicle wheel flat warning system comprising a first sensor, a second sensor and a controller. The first sensor may be located adjacent to a first side of a rail to provide data associated with a rail vehicle wheel passing over the first side of the rail. The second sensor may be located adjacent to the first side of the rail to provide data associated with the rail vehicle wheel passing over the first side of the rail. Furthermore, the controller may be in communication with the first sensor and the second sensor to receive data from the first sensor and the second sensor. The controller may determine a potential wheel deformity based on the data received from the first sensor and the second sensor.

Abstract: Aspects of the present disclosure involve a system and a method for predicting locomotive engine bearing failures (e.g., main bearing failures). In example embodiments, the method may access locomotive data about a particular locomotive engine, and generate a set of element concentration trajectories therefrom. Each element concentration trajectory includes a measure of element concentrations in the locomotive engine's oil over a period of time. The method further includes determining a health score of the locomotive engine based on a comparison of the set of element concentrations with a set of baseline element concentration trajectories that are representative of element concentrations of a group of locomotive engines' oil over the period of time. The health score provides a measure of the likelihood of bearing failure in the particular locomotive engine. A message regarding the likelihood of bearing failure may then be provided.
