Overview
- SEMAR confirmed the main locomotive derailed on Line Z near Nizanda, between Chivela and Nizanda, at approximately kilometer Z-230+290 toward Matías Romero.
- The convoy carried two locomotives and four passenger cars with 241 passengers and 9 crew, and emergency teams attended and evacuated those on board.
- Federal and state agencies mobilized, including SEMAR, Oaxaca civil protection and police, and the IMSS, after President Claudia Sheinbaum said the government was monitoring the response.
- Officials have not issued casualty figures, while some outlets report at least 10 people injured receiving medical care.
- Investigators are conducting peritajes to determine whether mechanical issues, track conditions, or external factors caused the derailment, as unverified images online suggest severe damage including a fall into a ravine.
