| Description | The resilience of coastal railways to natural hazards such as storms and surges is an important aspect of disaster risk mitigation in those countries with vulnerable transport infrastructure. The risk model developed in this work is spatially specific to the Southwest England rail mainline through Dawlish but has application in other coastal railway alignments throughout the UK, such as in Cumbria, west and south Wales where similar hazards are encountered and the engineering assets were constructed during the same era and using similar design methods. Adaptation of the hazard elements to include local meteorological and wave environments would allow direct usage of the model in those regions. The model may also be of use in coastal railways subjected to diverse natural hazards such as Hurricane, Earthquakes and Tsunami. In addition, the damage mechanisms and failure pathways discovered show cascading effects which increase the severity of an event. Often insurance risk will underestimate these events due to not taking account of the cascading behaviour. |
| Exploitation Route | The work proposes an understanding of the failure of railway assets in the coastal margin. As more people populate the coasts around the world, infrastructure must be built to service this demand. Understanding the risks involved with infrastructure and how they respond to different hazard scenarios is of paramount importance to the insurance industry, the infrastructure owners, planners and central government. |
