Özet (abstract)

Abstract Ensuring the feasibility and robustness of train operations in stations and network nodes is receiving more and more attention given the trend towards a stronger integration of timetabling and network planning in railway systems. Existing approaches for robust station routing most commonly rely on the maximization of buffer times between consecutive trains. This view, however, neglects indirect dependencies between trains which may exacerbate delay propagation in the station, as well as dwell-time supplements. In this work we develop a new exact robust routing approach for stations that allows to minimize the expected delay caused by primary delays, generalizing delay absorption concepts used in timetable stability analysis and recoverable robustness. The methodology is based on a mixed-integer linear programming (MILP) approach for modeling delay propagation that takes both direct and indirect train dependencies into account. We test our approach on three railway stations from the Netherlands, where it is found that the optimized routings of the new method can reduce the delay propagation compared to buffer-based methodologies.
