Short summary

Railways in floodplains and coastal areas are frequently damaged by floods. Railway systems suffering scour damage face interruption of operation for weeks. This substantially limits the socioeconomic activities that rely on the transport service provided by the railway. This paper proposes new fragility curves for railway embankment and ballast scour. This contributes to expand our ability to estimate risk of flood hazard on our society more holistic than ever.
