Deadly Mexico City Metro collapse

Tue May 04, 2021 11:18 am

Surprised this isn't being discussed yet. Awful news from Mexico City of a metro overpass collapsing onto a busy road, taking a train with it.

https://www.bbc.co.uk/news/world-latin-america-56977129

An interesting point from the article was that local residents reported cracks in the structure after the 2017 earthquake. It was reportedly repaired, but interesting to see if further undetected damage led to the collapse. This line is one of the newest in the system too, only opened a decade or so ago.

Very disheartening to see...until COVID, CDMX was really enjoying a resurgent environment of investment and improved reputation. Unfortunately, corruption is fairly endemic in Mexico's public works construction...we'll have to see what comes of this.

Absolute tragedy. Up until the late 90s, the subway worked flawlessly. Then, since 1997, the mayor is democratically elected rather than designated by the president. Before this, the subway was pretty much built (10 out of 12 exisiting lines), operated and subsidized with federal funds. That is not the case anymore. I'm not loging for the past, just stating that things have changed and local governments have been unwilling or unable to properly fund and operate this complex system.

The two newer lines; 8 and 12 have been built since. The maligned one is the newest: Line 12. Built in haste following a winding path among what were originally irregular settlements, it was never part of any master plan and doesn't lead itself to have trains circulating at relatively high speed. From the get go, there were problem with the rails bending. Corruption may have played a role here. The new path was longer (32km), more complicated and with incompatible and cheaper technology (non-pneumatic wheels). Bigger works yield bigger cuts for corrupt politicians I guess.

Some versions say employees denounced damages from the 2017 earthquake that were not dealt with. We'll see. Employees belong to a strong and rather corrupt union themselves. I have no problem thinking nothing was done because of a flawed conception of "savings" (very prevalent with our current federal and local governments) and sheer incompetence (also prevalent). Lots of ideology and politics, little technique and management.

It has to be said that there was a single deadly accident in 1975. The last five years or so there have been THREE. As I said, the subway used to work just fine.

Just awful - Mexico City deserves to know how this happened and whether anyone needs to be held criminally accountable

Think they had an earthquake not all that long ago maybe that had something to do with it. The rail line seems fairly new.

This reminds me of the negligent bridge collapse down in Miami

Love how every "travel blogger" says they will never fly AA/Ethihad again and then says it again and again on subsequent flights.

The question is was the bridge checked correctly after the earthquake. And also was it conceived and built right.

The answer to the first question is a resounding no, since local community noticed for months the structure was damaged. There were pictures posted on Twitter from last October showing a visible crack.
