System, method and computer software code for detecting a physical defect along an insertion path

Route defect detection system for a powered system, the route defect detection system includes a control system which is connected to the driven system for applying a tensile force, and a processor to an unplanned change in the application of the tensile force and / or which in some other way with the pulling force the driven system is related to determine. On the basis of unscheduled change, the processor determines a type of a defect, which is encountered along an insertion path. There are also a method and a computer software code stored on a computer readable medium and executable with a processor is disclosed for a power system for detecting a defect along an insertion path.
