Dear BART: it’s not like society just invented escalators. This is a fairly well-understood technology, used world-wide.
How many dedicated escalator repair personnel do you have? How many spare parts do you hold onsite? Why does this escalator keep breaking?
How do you keep them running?
“People,” Likhachev says. His division has a staff of 3,000. It has workers posted at every station during operating hours. It has a 20-member emergency rapid response team. It also has its own factory churning out spare parts, “so we don’t have to rely on suppliers.”
This is not to say that all escalators work all the time, because they don’t. But let’s be clear about one thing: “We do not have escalators out of order,” Likhachev says. “We close some for repair.”
