Optimal rerouting of short-turning trains during track obstructions

Railway trafic controllers have only limited decision support to deal with disruptions. The aim of this research is to provide an algorithm to compute conflict-free routes for trains that cannot continue their planned operation due to a track obstruction. In case of complete blockage, trains need to short-turn at the closest possible station to...

An Optimization Model for Simultaneous Periodic Timetable Generation and Stability Analysis

We present an optimization model which is able to generate feasible periodic timetables for networks given the line structure and the requested line frequencies, taking into account infrastructure constraints and train overtake locations. As the model uses the minimum cycle time as the objective function, the stability of the timetable is also...
