Robust railway station planning: An interaction between routing, timetabling and platforming

In this paper, the authors consider complex, busy stations whose limited capacity is one of the main reasons of delay propagation. The goal is to improve, during the planning phase, the robustness of a complex station by fully exploiting the potential of the available capacity. The main feature of the authors' approach is the interaction between routing decisions, timetabling and platform assignments. By altering one of these, slack can be created to allow improvements by the others as well. An objective function that maximizes the time span between any two trains is defined and the timing of the trains and the way how trains are routed to the platforms are optimized in the scope of this objective. By maximizing the spread of the trains, potential conflicts are avoided which is beneficial for – but not identical to – robustness. Using this approach, the robustness in the station zone of Brussels, Belgium’s main railway bottleneck, can be improved by 8%. Next to that, the amount of knock-on delay arising due to conflicts within this area can be halved. This performance of this approach is confirmed by a second case study based on the station zone of Antwerp.
