Abstract

The DB Netz AG is the most important railway infrastructure company in Germany and operates a railway network with a total length of about 34,000 km. One of the main tasks is to generate timetables to sell train-paths or enhance the infrastructure by eliminating bottlenecks. The creation of a timetable for the complete network is complex and time-consuming so there are efforts to atomize this process in essential parts. The software-system TAKT of the professorship “Verkehrsstroemungslehre” at the TU Dresden automatically generates timetables for complex railway networks on the base of periodic event scheduling problems (PESP) by using specialized algorithms. It provides practically useful solutions in appropriate runtimes because of its up to date techniques like a SAT-solver and an innovative routing-algorithm, which finds a well-suited train-path in the network automatically. To calculate a timetable for the whole Eastern German long-distance, regional and local traffic the solver needs a computation time of only few hours. In summary with the use of TAKT at DB Netz timetables for passenger and freight traffic can be generated automatically with a great quality in a very short time.
