Abstract: Within the railway value chain (timetabling, line planning and vehicle scheduling, etc.) the coordination of the single planning steps is a key success factor. Hence, we consider the integration of the line planning and the timetabling process as crucial for timetabling in practical applications. To address this, we present a `track-choice' extension of the commonly known method for the generation of periodic event schedules `PESP'. The extension makes use of the mesoscopic track infrastructure representation in the line planning and timetabling system Viriato, a system that is widely used by public transport planners and operators. Taking into consideration the technical and operational constraints given by rolling stock, station and track topology data on one hand, and the commercial requirements de ned by a given line concept on the other, the method presented generates periodic timetables including train-track assignments. For this, we make use of the `service intention', a standardized data structure for the line concept consisting of train paths and frequencies. Due to the utilization of infrastructure based track capacities, we are also able to assess the feasibility of the line concept given. Additionally, the method allows for handling temporary resource restrictions (e.g. caused by construction sites or operational disturbances) up to a certain degree. The methods presented here are part of a planning framework which is currently developed covering relevant parts of the railway value chain.
