To formalize the process of spreading train delays at the railway station, a modified mathematical epidemiological SIR-model has been developed, which allows to numerically assess the speed of trains of different categories and the size of their time compensation reserves on the reliability of the normative train schedule. This macro-level approach to modeling the propagation of train delays involves the use of machine learning to gain knowledge of real train delays at the site when searching for parameters of differential equations of the SIR model and modeling the propagation of delay propagation at different speeds. To find rational time reserves for the resumption of trains of different categories depending on the number of detained trains in the schedule, a method based on modeling the distribution of train delays at branched railway tracks has been developed. This speeds up the accuracy of complex and lengthy train delay calculations, taking into account the impact of the "network effect".
