I don't know for sure, but wonder whether people walking up the escalator
tend to stay further apart than those who stand still? If so, walking may
actually reduce the capacity.
It may reduce the number on the escalator at any specific moment, but
it's unlikely to reduce the number tranported from the bottom to the
top per unit of time, since people who walk spend less time on the
esclator than people who don't.
