I wonder why TfL don't speed up the escalators a bit when the demand is
high?

They are already quite fast, compared to many countries. The slowest
escalators I recall are those at Seoul (Incheon) Airport, which has an
underground shuttle train to reach many of the gates - with two long
stages of escalator to reach the stations each end. If they went any
slower they'd be going backwards! It's a shame because the rest of the
airport is excellent.

According to the paper I quoted the other day LUL escalators move generally
at 43.2 m/min. I can't find a Moscow figure but speeds up to 60 m/min are
considered acceptable for public use, it appears.

According to "The Vertical Transportation Handbook" (1998, available on
Google Books) speeds of up to 61 m/min are used on the Moscow metro -
although it states that this is primarily to reduce the travelling time
on its very long escalators rather than to increase handling capacity.

It adds that modern escalator speeds (presumably in the USA) have been
standardised at 30 m/min.
