The Nine-Second Window
The journey began like any other, but in a matter of seconds, it descended into chaos and tragedy. A reconstruction of the fatal moments reveals a sequence of events so rapid that passengers had little time to react before catastrophe struck.
Based on witness testimony and investigation findings, the final moments of the Iryo train have been pieced together, offering a harrowing glimpse into the disaster that claimed 45 lives. The incident unfolded with terrifying speed, transforming a routine commute into a scene of devastation.
A Sudden, Violent Jolt
The first sign of trouble was not a screech of metal, but a profound and unsettling sensation. Antonio Méndez, a passenger in the fifth car of the Iryo train, described the initial moment with chilling clarity: "De pronto, sentimos como si atropelláramos algo, una sensación de subir y bajar, como si pasáramos un bache o un badén."
He continued, "e inmediatamente después empezó a temblar el coche de izquierda a derecha. Nos agarramos a los asientos porque parecía que íbamos a volcar." This account was not an isolated one; several other travelers in the same carriage reported an identical experience—a sudden, jarring impact followed by violent oscillation.
"De pronto, sentimos como si atropelláramos algo, una sensación de subir y bajar, como si pasáramos un bache o un badén."
The collective testimony paints a picture of a train that first lurched upward and downward, as if hitting a severe obstacle, before beginning to shake violently from side to side. This initial jolt marked the beginning of the end, the precise moment the train left the rails.

The Descent into Chaos
Following the initial impact, the train's movement became erratic and uncontrollable. Passengers, gripped by fear, clung to their seats as the carriage swayed violently, creating a terrifying sense of impending doom. The sensation of potentially overturning was immediate and overwhelming.
The sequence of events, from the first jolt to the final, catastrophic collision with the oncoming Alvia service, transpired in a mere nine seconds. This incredibly brief window contained the entire tragedy, leaving no time for effective response or escape. The derailment itself was the direct catalyst for the subsequent impact.
- Initial jolt and sensation of climbing and falling
- Violent side-to-side shaking of the carriage
- Passengers bracing for a potential rollover
- Derailment and collision within nine seconds
The investigation's reconstruction, informed by these firsthand accounts, confirms the terrifying speed at which the situation deteriorated. What began as a minor disturbance rapidly escalated into a fatal loss of control.
A Coordinated Reconstruction
To understand the precise mechanics of the disaster, a detailed reconstruction was undertaken. The effort was a collaborative one, involving multiple specialists to analyze every available piece of data. The project was coordinated by Kiko Llaneras, Daniele Grasso, and Brenda Valverde Rubio.
The visual and analytical components were developed by a dedicated team. Ruth Benito handled the design, while Fernando Anido led the development work. To bring the events to life, Carmen Castellón and Jacob Vicente created a detailed 3D animation, allowing for a frame-by-frame analysis of the train's movements. Yolanda Clemente produced the accompanying graphics, and Julio Núñez provided additional information for the reconstruction.
This multi-disciplinary approach ensured that the final account was not only based on witness testimony but was also supported by technical and visual analysis, providing a comprehensive view of the tragedy.
The Human Cost
Beyond the technical reconstruction lies the profound human tragedy. The 45 lives lost represent individuals, families, and communities forever altered. The accounts from survivors like Antonio Méndez provide a visceral, personal dimension to the event, highlighting the terror and helplessness experienced in those final moments.
The shared experience of the passengers in the fifth car underscores the suddenness of the disaster. Their collective memory of a "bache" or "badén"—a bump or a pothole—became the first and last warning of the catastrophe that was about to unfold. The image of passengers gripping their seats, fearing a rollover, is a stark testament to the human experience within the technical failure.
Each detail from the investigation adds another layer to the story, transforming abstract statistics into a narrative of real people facing an unimaginable situation with no time to prepare.
Key Takeaways
The reconstruction of the Iryo train disaster reveals a tragedy defined by its terrifying speed and suddenness. The entire event, from the initial jolt to the fatal collision, was contained within a nine-second window, leaving passengers with virtually no time to comprehend or react to what was happening.
The consistent testimony from those on board, describing a sensation of hitting an obstacle followed by violent shaking, provides a crucial human perspective on the technical failure. This account, combined with the detailed visual and analytical work of the reconstruction team, offers the clearest picture yet of the disaster's final moments.
Ultimately, the story is one of catastrophic failure and immense loss, a stark reminder of the fragility of safety systems and the devastating impact when they fail. The memory of those nine seconds will forever be linked to the 45 lives that were abruptly ended.
