A system to facilitate reducing false train stops includes an infrared bearing scanner that is coupled to a processing unit. The processing unit is programmed to receive inputs from the infrared bearing scanner, generate a bearing profile for each bearing passing the Hot Box Detection System, assign a classification to each bearing profile, determine a quantity of bearing profiles assigned to each classification, and generate a maintenance alert if the quantity of bearings assigned to at least one classification exceeds a predetermined threshold. A method of reducing false trains stops is also described herein.
