Aim: To investigate and develop an approach for evaluating railway resilience through considering railway faults and disruptions
Background
Currently railway safety evaluation is carried out using traditional techniques for identifying potential hazards and determining their frequency of occurrence and the resulting consequences. In addition to component and system failures and human errors, nowadays complex systems such as railways are subject to a range of additional threats, such as terrorism, cyber-attacks and wider technology-based vulnerabilities, as well as being significantly affected by natural hazards and climate change. This is a major challenge, especially when increasingly clear implications of climate change, such as severe weather, can cause a loss of life, such as in the Carmont derailment in 2020. Recent advances in resilience engineering offer a strong alternative to traditional approaches in evaluating railway safety, especially when railway services are expected to be safe, reliable and resilient (i.e. able “to anticipate, absorb, adapt to and/or rapidly recover from a disruptive event”, as per resilience definition by the UK Government).
Proposed project
The proposed project will be based on simulation and analysis of disruption scenarios on the network, which will be used to analyse the effects of these disruptions, depending on their location, passenger numbers affected, frequency and severity of consequences. Vulnerable parts of the network will be identified and analysed in terms of different threat types. This type of analysis can be used to evaluate current operation and maintenance standards and their effectiveness for reducing overall railways system risk and improving resilience to threats. In addition, an optimisation framework can be developed in order to propose best response strategies when threats occur.
Such a methodology can then be used to make better-informed decisions in railway operation and maintenance. It can potentially improve railway network resilience by reducing vulnerability to threats, such as deteriorated infrastructure, natural hazards and cyber-attacks, and enhance network recoverability by enabling prompt responses and minimising consequences
