Background and Overview
On the morning of December 28, 2025, a tragic accident occurred when the Interoceanic Train derailed in Asunción Ixtaltepec, Oaxaca. This unfortunate event resulted in at least 14 fatalities and left 98 people injured, as reported by the Mexican government and the Navy Secretariat (Semar).
Key Details of the Accident
The derailment took place while the train, departing from Salina Cruz en route to Coatzacoalcos, went off the tracks in a section known as “Curva de la Herradura.” This caused several carriages to fall down an embankment, leading to multiple injuries.
Passengers and Response
The train was carrying 241 passengers and nine crew members. Thirty-six individuals remain hospitalized, with at least five in critical condition. Emergency response teams and naval personnel have been working tirelessly since the accident to conduct rescue operations and provide medical assistance.
Official Response
President Claudia Sheinbaum Pardo confirmed the number of victims and ordered direct attention to affected families, along with medical assistance in IMSS and regional hospitals. She also directed the mobilization of Semar, IMSS, and IMSS-Bienestar personnel to coordinate hospital care and support for the displaced.
Victims are receiving medical care in units across Matías Romero, Salina Cruz, Juchitán, and Ixtepec. Sheinbaum mentioned that investigations are ongoing to determine the cause of the incident.
The Investigation
A week after the accident, the Federal Attorney General’s Office (FGR) completed post-mortem examinations on the deceased and initiated an investigation to clarify the accident’s causes. The site remains restricted, guarded by the National Guard and federal personnel, as experts review the railway infrastructure and operational conditions.
Organizations such as the Rail Transport Regulatory Agency (ARTF) are collaborating with FGR to analyze the train’s “black box” and identify any technical failures, excessive speed, or other operational causes.
Local Impact
In the communities of the Isthmus of Tehuantepec, the accident has caused shock and grief. Residents from Nizanda, Chivela, and Asunción Ixtaltepec recount scenes of chaos as families search for news about their loved ones across hospitals and care centers.
Interoceanic Train services have been temporarily suspended, and alternative routes like tourist buses have been established to serve passengers affected by the railway disruption.
Families of some injured individuals have reported difficulties accessing specialized care due to hospital overcrowding and a shortage of specialists in nearby healthcare facilities.
