The vulnerability of rail transport systems facing flood hazard, increased by the climate change, is a burning issue for the future urban risks management. Analysing the resilience of rail transport systems against flood hazard appears necessary for improving the proper functioning of cities that strongly depend on such critical infrastructures. The critical infrastructures are complex systems in which the components are particularly interdependent. This interdependency implies many failures caused by cascade effect within the system. From dependability methods, this paper provides a global methodology in order to automatically produce the chains of failures caused by cascade effect within a rail transport system facing to a flood hazard.
