Track Broke Day Before Spain's Deadly Train Accident and Went Undetected

Investigators say a voltage drop went undetected for 22 hours, and the report rules out driver error, sabotage and terrorism.

  • On Wednesday, The Guardia Civil revealed that tracks near Adamuz broke 22 hours before the fatal derailment, yet signalling systems failed to trigger an automatic alert due to a configuration flaw.
  • Hitachi Rail told police the system only generates warnings if voltage drops below 0.780 volts; because voltage remained at 1.5 volts, the system interpreted the track as safe despite Adif's 2017 specifications.
  • A dynamic inspection detected a "vertical acceleration defect" two months prior at the break site, yet monitoring efforts proved insufficient. Investigators are examining "poor welding" concerns and technician experience requirements.
  • The disaster claimed 46 lives after the Malaga-Madrid train derailed and collided with an Alvia service. The CIAF detected "inconsistencies" in subcontractor documentation, casting doubt on signatures despite Adif's "correction" submission.
  • Toxicology tests and analysis by the RJU definitively ruled out sabotage, terrorism, and driver error. The official report confirmed both professionals acted correctly, describing the collision as "completely unexpected and without any time to react.
