There is a trade-off in scheduling between a punctual and reliable “system railway” with lots of running time supplements on the one hand and preferably short running times in addition to a high availability of additional train slots on the other hand. In this paper the effects of different allocations of time supplements on railway infrastructure providers, railway operating companies, goods and passengers will be shown.
At first, scenarios with different allocations of time supplement will be developed. According to each scenario, parts of the running time supplement will be shifted from each line respectively line section to the subsequent stop. Afterwards, these scenarios will be analysed in their effectiveness of achieving operational and commercial targets. Parameters for different lines will be determined by a multitool- analysis. The parameters are either extracted from the timetable construction or the simulation of the railway operation. These parameters vary due to the different allocation of the time supplement in the scenarios. Later, monetary values will be assigned to the parameters for comparing the scenarios with each other. The calculations will be made using different monetary values due to the different possibilities of evaluating the delay respectively the running time.
The profit and the loss of each scenario compared to the current status will be demonstrated separately for the above-named groups that participate in the system railway.
