RED 49 - Past at Danger

Our railways are the safest form of land transport in the UK. This is because generations of railway men and women have learned lessons from incidents in the past. This special issue looks at some of the accidents and disasters that stemmed from signals passed at danger, and how we are using those lessons to prevent incidents today.

This edition looks at the risks in the early railway, what we can learn from our recent history, and how we are reducing risks even further for the future.



The programme includes:

  • How Automatic Warning Systems (AWS) work
  • How Train Protection Warning Systems (TPWS) work
  • Signal Sighting
  • Signal Passed At Danger (SPAD) Risk Reduction Strategy

A look back at some of the major incidents in railway history. We learn how the rules and systems put in place protect us today, making us the safest form of land transport in the UK.
