Network Rail is undertaking a programme of adaptation pathways across the network to develop a long-term strategic adaptation plan and identify priority areas for further adaptation investment. This approach will help identify those parts of the network which may require transformational change to enable safe and reliable services to continue in the future.
Further, we recognise that the UK rail network is large and diverse, with different landscapes and communities facing different climate risks. Network Rail has produced a Weather Resilience and Climate Change Adaptation (WRCCA) plan for each of its five regions. This allows Network Rail to better identify, at a regional scale, those routes most at risk from climate change and extreme weather events. In 2026, 14 TOCs will also submit their first WRCCA strategies. As most TOCs operate over confined geographical regions, these will add further detail to our understanding of regional risks.
