Let the Train Take the Strain?

A relatively minor part the UK's Network Rail 5 year up-grading programme is currently 'earmarked' to deal with climate change. The funding allocated for drains; embankments and other measures amounts, however, to £2.8bn of a £45.4bn total. This is not an insignificant amount of money but it's unlikely to prove sufficient (https://www.theguardian.com/business/2024/apr/03/network-rail-investment-plan-climate-crisis-extreme-weather). £2.8bn sounds a lot but it's unlikely to 'future-proof' the UK's rail system. Climate change is already here. Weather will just become less easy to predict. Record temperatures are likely to cause rail lines to distort. Increased rainfall greatly increase the probablity of major flooding and landslide events. Fires are likely, in nearby vegetation. This is just the impact on rail. Just imagine the bill for the UK's road system?
