MEXICO CITY (AP) — The mayor of Mexico City announced Thursday that 6,060 National Guard officers will be posted in the city’s subway system after a series of accidents.
Mayor Claudia Sheinbaum said a series of mechanical problems in recent months may have been due to “not normal” causes. Sheinbaum appeared to suggest, but did not say, that it could involve some form of sabotage.
“In recent months, incidents have been occurring that we categorize as not normal,” Sheinbaum said, adding that she had asked President Andrés Manuel López Obrador to dispatch the quasi-military National Guard officers and that he agreed.
Sheinbaum said Guard officers would be posted at subway stations “and some other facilities” in the transport system and would be there “for some months.”
She did not explain how the Guard officers, mostly drawn from the army and assigned to law enforcement, could help control a situation that appears to be caused by maintenance, design or operational flaws.
Accidents on the city’s subway have been a recurrent embarrassment for Sheinbaum, who is considered the most likely candidate of López Obrador’s Morena party to succeed him in the 2024 elections. Like the president, Sheinbaum often ascribes setbacks to a conservative conspiracy against her.
The latest accident came Saturday, when two subway trains collided in a stretch between stations, killing one person and injuring dozens more. Local media reported there had previously been signaling problems on that stretch of track.
In May 2021, an elevated section of the subway system collapsed, causing 26 deaths and injuring nearly 100 people. An investigation blamed the structural failure on deficiencies in construction, and 10 former officials have been charged with a form of manslaughter, injury and damage to property, but none have been jailed.
Poor welding, a lack of maintenance, antiquated electronic systems and the city’s frequent earthquakes and soft soil conditions have all been blamed in the past for problems on the subway, but sabotage has never before been seen as a cause.
But in the last several days, Sheinbaum said there had been three “not normal” problems found on subway cars or tracks, including the failure of a tire “that had just been inspected.” The city’s subway cars run on both tires and rails.
The Mexico City subway system has 226.5 kilometers (141 miles) of track and 195 stations. It serves an average of 4.6 million passengers every day.
