Construction ‘deficiencies’ behind deadly Mexico City subway collapse, report says

MEXICO CITY – A preliminary report by experts into the collapse of a Mexico City elevated subway line that killed 26 people placed much of the blame Wednesday on poor welds in studs that joined steel support beams to a concrete layer supporting the track bed.

The city government hired Norwegian certification firm DNV to study the possible causes of the May 3 accident, in which a span of the elevated line buckled to the ground, dragging down two subway cars. 

The report also said there were apparently not enough studs, and the concrete poured over them may have been defective; the welds between stretches of steel beams also appear to have been badly done.

MEXICO CITY (AP) — José Luis Hernández Martínez crossed Mexico City every day on subway Line 12 between his home on the city’s south side and the body shop where he worked repairing mangled cars.

The 61-year-old’s train had emerged from beneath the city and was jostling along the elevated portion far from downtown late Monday night when two of its bright orange cars suddenly fell into a void.

Hernández Martínez was killed instantly, his son Luis Adrian Hernández Juarez said, one of 25 people who died in one of the world’s largest subway system’s worst accidents. More than 70 others were injured.
