Deadliest European Train Crash Since 2013: Signal Failure and Human Error on the Madrid–Andalusia Line

A reporter on the scene breaks down the chain of events behind a deadly collision between two trains in southern Spain, the deadliest rail accident in Europe since 2013. The account covers the signaling outage, the erroneous instruction given to the Renfe train, and the emergency response witnessed roughly two hours after the crash.

■ Cause of the accident
- Signaling system failure at around 8:30 a.m. that automatically halted several trains
- A human error that sent the Renfe train an incorrect order to proceed at high speed
- The approximately 25 km the train traveled before impact, against standard protocols

■ Scene and response
- Scale of the police and emergency deployment, including fire crews and mortuary vehicles
- Passengers who were on board the two trains

■ Comparison with the January accident
- Both occurred on the Madrid–Andalusia line in southern Spain
- The January incident appears linked to track maintenance issues, while this one points to human error
