Climate change related risk for GB railway system Theme of recommendations Specific key recommendations (with relevant climate variables in brackets) Time scale for action System Changing patterns of precipitation with consequences for soil moisture levels and stability. Focus on lineside management issues which affect infrastructure and ‘weather and climate resilient’ design and management options with multiple benefits. Determine which earthworks debris detection systems are most effective (High precipitation, Low precipitation). Medium term Infrastructure

Climate change related risk for GB railway system Theme of recommendations Specific key recommendations (with relevant climate variables in brackets) Time scale for action System Increased risk of flooding from heavy rainfall events, high sea levels and storm surges with consequences for resilience of infrastructure and assets. Adaptive pathways and lifecycle cost analysis for reducing vulnerability of infrastructure, assets and
Take an ‘adaptive pathways’ approach, such as that developed by the Thames Estuary 2100 project to the long term management of the GB railway to improve the resilience of infrastructure to flood risk and storm damage (High precipitation, High winds, High sea levels and storm surge).
