A method for determining the optimal interval of virtually coupled trains

https://doi.org/10.46973/0201-727X_2025_3_155

Abstract

The paper proposes a method for modeling the optimal inter-train interval under conditions of random train delays, based on statistical data collected from the Trans-Siberian Railway. The relevance of the study is due to the need to take into account random deviations when developing a freight train schedule with an increased degree of reliability in conditions of decreasing inter-train intervals using interval control systems. Delays were modeled using the Chi-square, Gamma, Erlang and Weibull distributions to determine the minimum intertrain interval that ensures schedule stability without accumulating additional delays. Recommendations are proposed for optimizing the technical speed of movement and introducing buffer time to prevent possible disruptions to the schedule.
