ABSTRACT
Any operational response to extreme weather should consider both the immediate risk that it mitigates, and any secondary risk that the operational response will introduce. A whole system risk model has been produced that is designed as a decision support tool for the railway industry to improve the current operational responses to extreme weather events. This initial iteration of the model considers how speed restrictions may be applied to mitigate the immediate risk from soil cutting failures during extreme convective rainfall. However, the scope of considering whole system risk can be extended to other extreme weather scenarios and operational responses.
