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.
