Abstract. The paper presents the reasons for the emergence of one of the main defects of railway rails, such as cracking, and factors affecting its increase. It was found that vehicle cooperation with the rail and the forming of the rolling surface caused by the load, as well as the resulting rail stresses caused by the dynamics of rolling stock are the cause of the head-check of the rails. The influence of impact resistance on rail cracks in the occurrence of these defects is also presented.
