Though timetabling can account for some possible delays, in practice, external events still regularly lead to delays. Once trains are deviating from their schedule, conflicts can occur. A conflict implies that (at least) two trains require the same part of the infrastructure at the same time. Conflicts need to be resolved quickly in a way that disturbs the system as little as possible. Therefore, the impact on the whole network should be taken into account when solving conflicts. This paper discusses a heuristic conflict prevention technique capable of solving multiple conflicts together by reordering, retiming and locally rerouting trains. Based on a close-to-practice simulation tool where a simplified prediction horizon up to 10 minutes is considered, this technique is compared to FCFS. Results show significant improvements when comparing to FCFS.
