Accident on the Mexico City Metro activates emergency protocol for Aquiles Serdán
The impact occurred on Line 7 and caused a temporary suspension of service.
On the night of Friday, October 3, an accident occurred on the Mexico City Metro, resulting in the death of a woman at the Aquiles Serdán station on Line 7 of the Collective Transportation System (STC). Security cameras and eyewitness accounts are being analyzed to clarify what happened on the platform.
The incident occurred on the platform heading toward Barranca del Muerto when a moving train struck the victim in the head. According to initial reports, the woman—between 25 and 30 years old—had leaned toward the tunnel to check if the train was approaching. Witnesses indicated that she was unable to get away in time.
Initially, the hypothesis of an accident due to carelessness while crossing the yellow safety line was considered. However, minutes later, the STC itself released another version: "The person allegedly lost his life after trying to throw himself onto the tracks as the convoy passed," they stated in an official statement.
Given the severity of the impact, the emergency crews who responded to the scene confirmed that the woman was no longer showing vital signs. Metro paramedics performed life-saving maneuvers, but were unable to revive her. It is presumed that she died of head trauma, although the Forensic Medical Service (Semefo) will determine the exact cause through a legal autopsy.
As a matter of protocol, service was temporarily suspended at the station while rescue and evacuation efforts were carried out. Later, the STC reported that Line 7—which connects El Rosario with Barranca del Muerto—was operating normally again until the end of the day .
The Attorney General's Office (FGJCDMX) has opened an investigation to clarify what happened. As part of the investigation, the station's video surveillance cameras will be reviewed, and statements will be taken from eyewitnesses. The identity of the deceased woman has not yet been revealed.
The Mexico City Metro reiterated its call to respect the yellow safety line, stay behind it, and avoid approaching the tracks. This accident adds to other recent incidents that reopen the debate about protective measures on platforms, especially at stations with high passenger flow.
In addition to the immediate impact on service, the accident on the Mexico City Metro raised concerns among frequent commuters. On social media, several passengers expressed their concern about the lack of physical barriers on platforms, especially at high-traffic stations like Tacuba, Mixcoac, and Centro Médico. While the STC has implemented awareness campaigns, protective systems such as automatic doors have not yet been installed on most lines.
The incident also rekindled the debate on mental health in public spaces . Civic organizations such as Metro Seguro and Red de Apoyo Psicológico CDMX pointed out the need to strengthen the presence of trained personnel at stations, as well as improve signage for help lines. In some cases, rapid-care booths or direct contact points with emergency services have been proposed.
On the other hand, the accident on the Mexico City Metro highlighted the importance of response protocols. According to sources from the STC, the reaction time was less than five minutes from the moment of impact until the arrival of the first aid teams. However, users reported delays in resuming service and a lack of clear information during the operation .
The Prosecutor's Office is continuing its investigation and has not ruled out any hypothesis. Security camera recordings are expected to be analyzed in the coming hours, and statements will be taken from operational personnel, security guards, and witnesses. The goal is to determine whether there was a technical failure, reckless conduct, or a deliberate act.
Meanwhile, the Mexico City Metro reiterated its commitment to passenger safety. In a statement released this Saturday, the state-owned company emphasized that "the yellow line is a fundamental preventive measure" and that "crossing it puts the lives of passengers at risk."
These types of incidents, even if isolated, have a strong impact on public perception of the transportation system. The Metro transports more than five million people , many of them workers, students, and families who depend on this service to reach their destinations. Therefore, every incident like the one that occurred on Aquiles Serdán requires a review of protocols, increased surveillance, and improved infrastructure.
