In delay management the main question is whether trains should wait for a delayed train or should depart on time. In the traditional delay management models passengers always take their originally planned route. In the latest literature they used re-routing of passengers and made significant improvements. However large instances could not be solved with their exact approach. Therefore in this thesis two heuristics are made that use re-routing and simple dispatching rules for the wait-depart decision. At the end experiments based on real-world data from the Netherlands Railway show that simple dispatching heuristics can be a good alternative in order to improve delay management when the optimal solution cannot be determined.
