The new escalators slow down when no-one's using them... I've seen that in
Stockholm, but is this the first one in Britain?

I thought that the DLR had them at one of the Greenwich extension
stations - Cutty Sark maybe?

I dimly remember reading that they were tried on the underground
decades ago but were eventually set to run continuously, it being a
seemingly insoluble problem in the days of steam, cogs, valves and
pulleys.
