Abstract: A major problem of public transport, and railways in particular, is to improve quality of operations by updating an offline timetable to the ever changing delays situation, in order to improve performance of the transport system. In railway systems, this relates to reduce train delays by reordering retiming or rerouting trains, and/or change connection plans and route advised to passengers, to improve their traveltime.

Key point of research is the interaction between the microscopic problem (of the infrastructure manager) to reschedule trains and the macrosopic, multi-decision maker problem (of the travellers) to find the optimal route in the network. In fact, changing passenger flows, respectively delaying trains and/or dropping passenger connections, varies the setting under which the two decision makers respectively interact. The interaction of the two decisions makers is mediated by the information one decision maker has about the other, and the service which is offered/used.

We analyse some solutions from the literature which correspond to Nash equilibria for different strategic settings of the game, and discuss different trade-offs that arise from the minimization of train delays and passenger travel times, which belong to the general structure and operations of public transport networks.
