Analysis of the Design, Operation and Maintenance Options to Provide a Fault Tolerant Railway System

It will be a challenge for the railway industry in the future to increase capacity whilst further improving reliability and the overall cost effectiveness of the system. Increasing the utilisation of the network by operating more hours per day, possibly with more freight transported at night, has been already stated as a possible solution to meet capacity requirements. However, a greater utilisation of the existing infrastructure would make the system more vulnerable to disruptions. Fault tolerance is the key property of complex system to deliver a reliable service. This paper introduces a methodology involving simulation, failure modelling and optimisation techniques, to systematically analyze options that may contribute to produce a fault tolerant railway system. A network modelling tool based on Petri Nets has been developed in order to evaluate the impact of different design strategies on the overall system performance. Numerical simulations for a railway network case study under different scenarios are provided and results are discussed.
