Abstract
The authors propose the idea of ultra-high-frequency rail network timetabling. In such a timetable, the scheduled trains will take very diverse routes on a given rail network to meet the diverse needs of the passengers and to enable ultra-high-frequency train operation. However, at junctions where two or more lines meet, the level crossing interference between different railway tracks will form the bottleneck for the realisation of such high train frequency. The typical example of this can be seen at crossovers between fast and slow lines on the quadruple track railway paired by use. To reduce such level crossing interference, the authors propose the simultaneous crossovers of two trains in both directions at crossover tracks, and the installation of multiple crossover tracks at one junction for realtime selection of the optimal route. In this paper, the authors present the detailed calculation of headways between trains at this kind of crossover tracks, which will form the basis of the authors’ future research into their ideas.
