“…Kozan and Burdett (2005), Vromans et al (2006) and Harrod (2009) have shown that SRT has a significant impact on capacity analysis, for instance, a slight change in SRT can have remarkable effect on the amount of capacity.…”

Abstract. Identifying railway capacity is an important task that can identify 'in principal' whether the network can handle an intended traffic flow, and whether there is any free capacity left for additional train services. Capacity determination techniques can also be used to identify how best to improve an existing network, and at least cost. In this article, an optimization approach has been applied to a case study of the Iran national railway, in order to identify its current capacity and to optimally expand it given a variety of technical conditions. This railway is very important in Iran and will be upgraded extensively in the coming years. Hence, the conclusions in this article may help in that endeavor. A sensitivity analysis is recommended to evaluate a wider range of possible scenarios. Hence, more useful lower and upper bounds can be provided for the performance of the system.

“…One way to increase reliability is to reduce the propagation of delays due to interdependencies between trains [38]. For example, the interdependencies can be decreased by reducing the running time differences per track section and creating more homogeneous timetables.…”

“…In fact, an exponential relationship exists between adding trains to a congested network and the expected level of network performance [12]. For the time being, the focus is on solving small primary disturbances, mainly because no timetable is robust enough to handle large disruptions without drastic realtime traffic adjustments [38].…”

Does the Liberalization of the European Railway Sector Increase Systemic Risk?

Recent large-scale blackouts and other incidents have shown that failures in network industries can have serious economic and social consequences. A large body of literature covers critical infrastructures (and their protection), but most of it is confined to a relatively restricted number of sectors such as electricity and information and communications technology (ICT). In addition, much of the literature discusses systemic risk in complex networks from an engineering perspective with the goal of mitigating risk using quantitative techniques. The railway sector is a critical infrastructure that shares a number of characteristics with electricity (e.g. interconnection), but it has received little attention when it comes to systemic risk. This paper analyzes the extent to which the liberalization of the railway system increases the sector's systemic risk, a pressing question in the wake of the creation of a single European railway market. The paper also discusses the broader issue of the governance of systemic risk in the railway sector, especially since the mitigation of risk tends to be limited to risk management from a technical perspective while ignoring the institutional dimension.

“…Vromans, Dekker and Kroon [14] describe an analytical method to evaluate how the minimum gap between two trains affects reliability. An adequate method of evaluating how a system reacts to delays and how changes affect this is simulation, as described for example in [3,10].…”
