At 7:43 PM, the quiet of Córdoba’s evening was broken. Three of the carriages of a high-speed Iryo train lifted, twisted, and slipped off their track as it was leaving the Córdoba–Julio Anguita station. A southbound Renfe train carrying people on their way home or away collided head-on in a matter of seconds. Once precisely engineered, steel suddenly became volatile. It was Spain’s deadliest rail accident in more than ten years, with 45 fatalities and 292 injuries.
On paper, the trains were neither outdated nor badly maintained. Only three days prior, the Iryo had passed its final inspection. Less than a year ago, the tracks, which are a part of the nation’s renownedly vast high-speed rail network, underwent a €700 million renovation. However, investigators discovered a 40-centimeter weld break—a tiny opening that proved to be lethal.

This incident is especially unsettling because everything seemed so commonplace. There was excellent visibility, the track was straight, and speed limits were respected. It wasn’t sabotage, rain, or speed. It was a crack that was literally hiding in plain sight.
I was struck by the detail of how something so tiny in size could have such a profound emotional impact.
With ruthless urgency, the aftermath developed. In a nearby sports complex, a temporary triage center was established. For identification, DNA samples were taken from family members in several cities. As flights were added in a hurry, many passengers were left stranded in stations overnight. The suspension of rail service between Madrid and Andalusia for several days was particularly painful in a nation where train travel is ingrained in daily life.
The visit of King Felipe VI and Queen Letizia, who toured the wreckage with somber faces and well-chosen words, added to the tragedy’s weight. Political tensions were not significantly reduced by their presence. Despite growing criticism, Transport Minister Óscar Puente remained steadfast. He declared, “I have a clear conscience,” but not everyone agreed. Especially after earlier warnings from the national train drivers’ union, SEMAF, the opposition called for accountability. They reported track degradation in August 2025, including in the vicinity of Adamuz. It seems that their warnings were ignored.
The incident also demonstrated how hidden vulnerabilities can affect even the biggest high-speed rail network in Europe. Second only to China, Spain has more than 3,900 kilometers of high-speed rail, but in just two weeks, there have been two significant derailments. Two days after Adamuz, a commuter train near Barcelona collided with a collapsed wall, killing the driver and injuring numerous others. That crash also sparked concerns about weather resilience and infrastructure management, particularly in the wake of Storm Harry’s days of intense rain.
In the Adamuz crash, the Renfe train suffered the most damage. Crumpling like tinfoil, its front cars were hurled down a four-meter embankment. On the other hand, the Iryo train suffered less obvious damage at the front, even though its rear carriages derailed first. The importance of milliseconds was later determined by analysis: some cars’ front wheelsets slightly compressed the damaged rail, allowing the trailing sets to roll over it—until they didn’t. The track eventually gave way. The sixth vehicle leaped. The others came after.
Researchers observed surgically specific patterns of wheel damage. Steel spun sideways and developed stress fractures as a result of the rail break acting like an abrupt cliff. Prior to the accident, three trains had crossed the break. All displayed damage to the wheels. None were halted.
Spain’s transport ministry has now committed €20 million in compensation, with staggered injury payments and €216,000 per family for each deceased person. However, no payout can genuinely make trust and grief work together. The financial assistance will provide relief for certain survivors. Others might find it offensive or inadequate.
The human element is what remains. The dog that was lost in the collision and discovered alive in the forest by firefighters a few days later turned into an unexpectedly symbolic tale. Not only because it gave people hope, but also because it served as a reminder that sometimes survival is determined solely by chance. These catastrophes are haunted by the randomness of who survives and who does not.
There will be more scrutiny of Spain’s larger rail system, but the issues are more profound. Will high-speed travel continue to be incredibly dependable in addition to being quick? When administrative and physical fault lines run underneath, can institutions regain the trust of their constituents?
Prime Minister Pedro Sánchez allowed time for the country to grieve by announcing three days of mourning. To stand amidst the devastation and grief, he called off his trip to Davos. In the meantime, SEMAF declared a strike in February, citing recent incidents and a string of warnings that were disregarded. They are emotionally and technically frustrated.
There is, however, cautious optimism. In addition to the failed track, railway engineers are currently looking into other similar sections of the network. Once viewed as auxiliary, structural sensors and diagnostic tools could soon take center stage. Spain could significantly lower future risk by incorporating real-time monitoring. It might eventually stop the next collision, but it won’t bring back the people who died at Adamuz.
There is a thin boundary between memory and motion. Progress is promised by high-speed travel. However, every second—and every signal—counts when that speed becomes disastrous.
