The paper deals with disruptions of a public transport system. Due to the growing population in most cities, a well functioning transport system and the management of possible disruptions becomes increasingly important. In our research, we mainly focus on severe breakdowns that involve a significant amount of planning. The proposed mixed integer linear programming model is able to handle an arbitrary number of transport modes, e.g., subway, tram, and bus. The main objective of the model is to provide sufficient capacity on all edges of the network in order to satisfy the passengers’ demand. Therefore, some lines may require to be re-planned or additional lines may have to be established to substitute distorted parts of the infrastructure. The newly implemented lines receive vehicles from operating lines, as vehicles have to be provided quickly in case of a disruption. The model is tested on two cases of the Viennese public transport system, which are solved via CPLEX.
