I understand one of the prerequisites for the introduction
of regenerative braking on the Central Line was a requirement to replace
older motors in escalators at stations. They share their supply with the
traction and needed to be able to handle the greater variations in supply
voltage.

Does that mean the escalators speed up slightly when a train brakes into
a station? Seems a good idea - get the passengers from the last train
out of the station quicker!

Hopefully they stay the same speed, but don't draw as much "external"
power for a few seconds.
