@amazeifystore: One loose wire. A green signal. A devastating chain of failures. At Clapham Junction, a redundant wire kept a track relay energized, making an occupied track appear clear. The 1988 crash killed 35 people. The inquiry also pointed to poor supervision, testing, and training. What safeguards could have caught the fault? #ClaphamJunction #RailSafety #EngineeringLessons #SystemsSafety #EngineeringFailure #SafetyCulture #TransportHistory #RiskManagement
