A hypothesis on homogeneity of groups of the similar electric train mechanical nodes was put forward to improve the reliability of the recognition of the technical condition of the mechanical parts of the rail rolling stock and the calculation of the critical parameter values. The parameters of the node vibration generated when the train moves were collected; a new technique was developed and the statistical analysis of the measured vibration parameters of the same-type nodes was conducted within the hypothesis testing experiment.
