Metro has recently had a huge budget deficit (despite raising the price of everything), and has started skimping out on maintenance. Today was a relatively hot day, and my guess is that something on the track popped, causing the wreck. If so, then there will be big time hell to pay.
Agreed. . .from basic escalator service to track maintenance to operators. . .they are all indications of a shoddy operations. We have been thus far very lucky.
