Selected simulation and experimental study of the CWR track

The article presents issues related to the CWR (continuous welded track) and discusses the problems associated with its operation. An important part of the article is the results of simulation tests carried out for the developed model of a CWR track loaded with various values of longitudinal forces that may occur during operation. The forces act in the rail due to the occurrence of thermal stresses with values depending on the temperature change of the rail. In addition to simulation tests, the concept of experimental tests that will be performed on a selected section of the railway line is also presented. The MS-02 device will be used to measure longitudinal forces under various load conditions and to maintain the contactless path. The results of measurements made in the exploited track will be used in the long term to verify and further improve the numerical models.
