N2  - In order to eliminate or reduce overall delay time of train group system in disturbed situations, a redundant time redistribution model for delays at multiple stations was proposed given fixed overall redundant time, with station delay as delay state and minimum expected average weighted delay time as an objective. Then, the model was solved by mathematical analysis method. Finally, its scientificity and effectiveness were verified through analysis on delay data of three stations on Beijing⁃Guangzhou high⁃ speed railway. The results show that by reallocating redundant time, the proposed model can achieve minimum delay with total expected delay being reduced by 7. 26%. It is proved to be scientific and effective as it reduces train group delays to a certain extent. © PHYSOR 2022 China Safety Science Journal. All rights reserved.<p /> <p>Language: zh</p>
