A recent train derailment in Oaxaca, Mexico, has drawn attention to public infrastructure safety. This incident follows a deadly 2021 subway collapse in Mexico City, which occurred during Claudia Sheinbaum's tenure as mayor. Investigations into the subway disaster cited faulty welding, inadequate inspections, and maintenance issues. Opposition parties blamed corruption and negligence, also criticizing Marcelo Ebrard, who is now the economy minister.
