The UK's rail network is one of the safest in the world, but this is a reputation that has been hard-won through a dark history of death and destruction. Each of these accidents has helped to prevent another in the future. Signals to Danger is a series of Podcasts exploring and explaining the worst disasters on the UK rail network. Using reports, inquiries, news articles and first hand accounts, we will dive deep into these accidents and understand what went wrong, who was effected and how each incident went on to change the railway going forwards.
