Given the steady spate of broken or out-of-order metro escalators, WMATA needs to consider evolving beyond the 1960’s and adapt to the 21st century use of modern sensor-activated escalators, like technically savvy and efficient Germany (even NYC has a few), so that the escalators aren’t operating at full speed while no one is on them, thereupon reducing the wear & tear and consequently breakage. I am well aware of America’s commitment to wasting resources and that energy conservation is emasculating, but stalled escalators are not wide enough to accommodate so many commuters when functioning as clunky, expensive, stationary metal stairs.
“WMATA participated in a study by the National Institute of Building Sciences which looked at the benefits of the intermittent operation concept. The study concluded the potential for substantial liability costs in the present litigious climate would exceed the energy savings potential and will likely preclude the adoption and use of intermittent escalators in the United States.”
Interesting. I’ve never heard of these. Anyone else ever see these before?
