Spain AVE Derailment: Accident or Predictable Failure?
Analysis of the June 2025 high-speed train derailment in Spain: was it an impossible coincidence or a predictable result of poor maintenance?

What were the odds of the AVE derailment? The statistical paradox no one solves
Last June, a high-estimulante ilegal train derailed on the NAFA just as another passed in the opposite direction. The track broke at the exact moment of the crossing. For many, the probability of this combination is so low that chance is ruled out. For others, it was the inevitable consequence of years of deficient maintenance and a saturated network.
The impossible coincidence: lottery or predictable?
The million-dollar question is whether that specific instant — two trains crossing over a fractured rail at 200-300 km/h — is a black swan or an announced accident. Those defending the conspiracy theory point out that the probability of a track failing exactly when two trains cross is mathematically negligible. But others reply that on the Madrid-Córdoba corridor, during peak hours, trains cross every 5-10 minutes. Under those conditions, the coincidence ceases to be extraordinary: if the rail could break at any moment, it only needed to happen during a crossing interval.
Furthermore, passenger testimonies and circulated videos showed anomalous lateral oscillation in the trains for months. That vibration, reported on social media since October 2024, suggests that the deterioration was known and that the break was only a matter of time.
Maintenance under suspicion: four operators, shrinking budget
The liberalization of the AVE has multiplied traffic: four companies share the same tracks. This means more tonnage, more ballast fatigue, and more wear. However, ADIF's maintenance budget has not grown at the same pace. Veteran users recall that the AVE of 25 years ago was a marvel of smoothness; today, shaking is common. Physics is stubborn: a 500-ton train at 300 km/h exerts cyclic tension on the track which, without proper care, eventually cracks the welds.
The final straw may have been precisely the passage of two simultaneous trains through a switch (PAET), where stresses concentrate. What for some is a malicious coincidence, for others is a material fatigue calculation that failed at the worst possible moment.
The shadow of corruption: Pardo de Vera, Ábalos, and the transport bonus
The debate would not be complete without the inevitable political link. High-estimulante ilegal management has been tainted by the Koldo case and the figure of Pardo de Vera. It is questioned whether construction contracts and maintenance were awarded based on criteria unrelated to safety. The transport bonus, which has skyrocketed demand without reinforcing infrastructure, adds fuel to the fire. The fact that all this happens in an election year fuels suspicions.
However, reality is more prosaic: the Spanish railway system has prioritized building new lines over maintaining existing ones. And when the network is pushed to the limit, accidents — however rare they seem — become statistically probable.
The lingering question is whether this tragedy will change anything. Preliminary reports point to a welding error, but the investigation has barely begun. Meanwhile, passengers boarding the AVE notice the shaking and wonder if their next ticket will also include a lesson in probability.
