Thanks all. I had thought that DOO on the tube was a 1980s phenomenon.

The Victoria stock uses a very simple 1960s system that's quite
different to that used in modern ATO trains. From memory, trains run at
either a standard restricted speed, or flat out, with no finer controls.

Its not quite that crude I don't think. I'm sure theres some intermediate
speeds. However despite its age IMO it provides a much more pleasent ride
than the ATO on the central line whose internal logic seems to consist of
"i'm going too fast , must slow down ... I'm going too slow , must speed up,
slow down, speed up, slow down, speed up". The hopeless software even makes
it consistently brake coming into some platforms only to speed up again
10 metres further along just to slow down again - St Pauls springs to mind.
Never mind the wasted electricity it can't do the running gear or track any
favours.
