EN It is currently not possible to experimentally identify specific operating conditions or sections of infrastructure for which certain values of the wear intensity of wheels and rails occur during rail vehicle driving.This paper shows the development of a new approach to characterize the wheel-rail wear by the means of visible and infrared light range imaging. The main assumptions of the undertaking, adopted methods, preliminary and anticipated results are demonstrated. On the basis of the results of preliminary tests in real operation conditions and on a tribological machine, it has been proved that the presented method can be implemented while monitoring the wheel-rail interaction. The issues that need to be solved in order to ensure the appropriate quality of measurement are emphasized, e.g. low emissivity of metal surfaces, difficult access to the wheelset of the vehicle and the presence of contaminants and third bodies in the wheel-rail contact. The utimate goal of the described undertaking is the development and experimental verification of a prototype of a measuring system to identify the wear intensity of the wheel-rail pair. The implementation of the method will contribute to the expansion of research possibilities in the field of the analysis of wheel-rail contact and to deepening the knowledge about its behavior in various operating conditions.
