The compilation of the periodic timetables in rail passenger transport is currently a new evolving trend that increases the efficiency of rail transport. However, for the development of transport science, it is necessary to constantly develop this system. The paper offers one way to contribute in this area and thus raise and improve this system of organizing rail transport. The aim of the contribution is to propose a methodology that evaluates the level of stability of periodic timetables based on operational and infrastructural factors. The methodology identifies operational-infrastructural factors that affect the stability and reliability of periodic timetables. Using scientific methods, it presents the method of their quantification and determination of the weights of these factors, which evaluate the line sections and transport points of the examined transport route. From a practical point of view, the methodology is generally applicable to other European railway networks. There is practical application of the proposed methodological procedure in the form of model examples for various transport routes in the final part of the paper.
