Comparison of microscopic and macroscopic approaches to simulating the effects of infrastructure disruptions on railway networks

Markus Zinser, Torsten Betz, Jennifer Warg, Emma Solinen, Markus Bohlin
2018 Zenodo  
The current state-of-the-art in timetable analysis in the presence of disruptions is to use railway microsimulation, which typically yields detailed results on infrastructure or timetable performance.  ...  Although there is some room for improvements in accuracy, the new approach appears promising, and we found no evidence against its suitability in the presence of disruptions.  ...  From the timetable, nodes of a graph are constructed, containing the information when a train is planned to arrive at and depart from a point on the railway network.  ...

Addressing nodal constraints on the capacity of railways

John Armstrong, John Preston, Chris Potts, Tolga Bektas, Dimitris Paraskevopoulos
2017 Proceedings of the Institution of mechanical engineers. Part F, journal of rail and rapid transit  
As demand for passenger and freight transport on Britain's railways increases, providing additional capacity and making the best use of the existing infrastructure are priorities for the industry.  ...  Since the stations and junctions forming the nodes of the railway network tend to form the constraints on route and network capacity, improved understanding of their operation and capacity characteristics  ...  Capacity utilisation assessments inform both of the above objectives, in that (i) the greater the number of trains being run for a given level of capacity utilisation, the greater the level of capacity  ...
