Abstract: Abstract This paper proposes a comprehensive approach for the railway scheduling problem, which starts with the commercial description of intended train services and has the goal of generating a conflict-free detailed schedule. The approach consists of three description levels with their corresponding interfaces and enables a hierarchical divide-and-conquer approach. The first step is the description of a formal structure for describing the service intention, including periodicity information. A projection scheme is used to create an augmented periodic problem. This augmented periodic timetabling problem is solved first globally on an aggregated topology and simplified safety model, and subsequently refined locally by considering all details of the infrastructure and train dynamics. Finally, the generated periodic conflict-free schedule is rolled out over the complete day to create a production plan fulfilling all requirements specified in the service intention.
