Investigating The Impact Of Timetable Properties On Delay Propagation On A Double-Track Line Using Extensive Simulation
2011 (English)Conference paper (Refereed)
Today many railway lines are operated close to maximum capacity. A common question asked is: “How is the quality of operation affected if one additional train/h is scheduled?” With the upcoming deregulation of operation, the necessity to be able to answer this question accurately increases when service operators that are denied train slots due to congestion demand a motivation.
The objective of this paper is to investigate how secondary delays on a congested double-track line depend on several parameters such as:
Each combination of settings of the parameters is investigated to capture possible interaction effects.
The infrastructure model consists of a fictitious double-track line with overtaking stations at regular intervals. A program that generates timetables and perturbation data according to specified input settings is developed. The output of the program is data files that can be read directly by the well-known simulation tool RailSys. This process makes it possible to simulate the hundreds of different timetables that are the result when the parameters investigated are varied. The outcome of the simulations is analysed to find the influence of the investigated parameters on the secondary delays.
