In the article the damage of the axle boxes of locomotives CHS-2 in operation are analyzed. The mostfrequently in use bearings of axle nodes are damaged (their rings and separators). On the basis of histogramsis determined that the distribution obeys the Weibull law. Based on the analysis of the nature of the damagethe main directions of improving the reliability of axle nodes of locomotives in maintenance are determined.To determine the technical condition of axle boxes the usage of the methods and technical systems based onthe analysis of parameters of vibration is proposed. The article presents a short analysis of existing methodsof diagnostics of the bearings of nodes. As a result of the calculation according to the criterion of uptime thetime of first diagnosis of axle equipment after repair is defined.To further determine the frequency of diagnosis the criterion of change of parameters of the technical state ofthe node is proposed to use. For the current conditions of the maintenance of locomotives the introduction ofdiagnostic systems that have the functions of anticipating and shaping the future recommendations accordingto the previous diagnostics would be as the most acceptable option.
