Abstract: The purpose of this article is to determine the critical velocities for five railway vehicle objects and to find possible generalizations of these results. It is done in the context of increasing the safety of travel on modern railways. The article discusses four methods of determining these velocities, and then the results obtained, mainly using one of the methods, are presented in tabular and graphical form. The chosen method is supplemented with the second one when higher accuracy or certainty is necessary. Finally, the results are discussed and the similarities and differences between them for different groups of railway vehicle class objects are shown.
