Abstrakt:
The paper describes a new method of developing the annual train timetable in the information system of the infrastructure manager in the Czech Republic. The system is accessible to the information systems of railway undertakings through a data interface that allows receiving and providing messages compliant with the TAF / TAP TSI specifications of the European Union. In order to develop a timetable, processes are designed for processing a new request, modifying and cancelling a request by the railway undertaking, deleting a route by the infrastructure manager, and processing data that is not needed at the time of path construction.
