A route defect detection system for a powered system, the route defect detection system including a control system connected to the powered system for application of tractive effort, and a processor to determine an unplanned change in the application of tractive effort and/or otherwise associated with the tractive effort of the powered system. Based on the unplanned change, the processor determines a type of defect encountered along a mission route. A method and computer software code stored on a computer readable media and executable with a processor are also disclosed for a powered system to detect a defect along a mission route.
