The article considers a calculation method of track component failure resulting from high-level bending stresses caused by the movement of the rolling stock. The method is based on the probabilistic nature of stress value in components, as well as statistic data on the fatigue properties of the metal from which they are made. The method is approved by the calculation example of the most dangerous failure types of turnout components but it can find a wider application. By using this method, the evaluations of failure change can be obtained for all design components that carry a cyclic load on change of their operation conditions.
