>How do escalators even fail like this? In the specific case it is a combination of lack of maintenance combined with bad maintenance. It seems like the firm that had the contract for the maintenance was cutting a few corners (removing or disabling existing safeties) to reduce "false alarms" and having a lesser numbers of calls to re-enable the escalators. I.e. the issue has nothing to do with the engineering or designing, which was fine, but rather with the (poor) maintenance performed.
