1. The last 3 cars from the Iryo train (Frecciarossa 1000) derailed for unknown reasons. It's a straight line, so this is extremely rare.
2. The Renfe train (Alvia) didn't have time to break and hit the derailed trains from Iryo, the two first cars derail as a consequence of the impact.
3. The Iryo train(Frecciarossa 1000), that caused the accident, was manufactured in 2022 and it passed a technical inspection just 4 days ago.
4. The renovation of this specific part of the infrastructure finished on May 2025, so it's practically new.
Spanish high speed trains are one of the best in the world and it had plenty investment from governments of different sign over the years. This has nothing to do with the regional network (Cercanias) and the local struggles in certain regions.
IMHO, this is a horribly timed accidental technical issue.
