Abstract: 

In this talk, I present an exact symbolic simulation method to compute the impact of delays in railway systems. This approach uses macroscopic railway infrastructure models and models primary delays of trains in a timetable by discrete probability distributions. The method is capable of computing exact probabilistic quantities like delay probability distributions and expected delays for timetable trains, or expected capacity usage of infrastructure elements within a given finite time window. In turn, these quantities allow us to examine timetable robustness and to identify problematic infrastructure elements.
