Актуальность исследования обусловлена необходимостью учета случайных отклонений при разработке графика движения грузовых поездов с повышенной степенью надежности в условиях уменьшения межпоездных интервалов с применением систем интервального регулирования. Проведено моделирование задержек с использованием распределений Хи-квадрат, Гамма, Эрланга и Вейбулла для определения минимального межпоездного интервала, который обеспечивает устойчивость графика без накопления дополнительных задержек. Предложены рекомендации по оптимизации технической скорости движения и внедрению буферного времени для предотвращения возможных сбоев в графике.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>график движения поездов</kwd><kwd>стохастические отклонения</kwd><kwd>межпоездной интервал</kwd><kwd>пропускная способность</kwd><kwd>виртуальная сцепка</kwd><kwd>тяжеловесные поезда</kwd><kwd>длинносоставные поезда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>train schedule</kwd><kwd>stochastic deviations</kwd><kwd>inter-train interval</kwd><kwd>capacity</kwd><kwd>virtual coupling</kwd><kwd>heavy trains</kwd><kwd>long trains</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Особенности эксплуатации железнодорожного полигона с порожним вагонопотоком / О.
