: Can't say it bothers me though I do think the ATO could do with a bit
more

speed
and

then

again
lets
: brake.. etc etc. I'm thinking someone should have mentioned the
concept of
: coasting to the systems programmers.

Doesn't this contribute to the shorter headways that ATO trains can
operate
compared to manually driven trains?

Yes and no. What I'm saying is that if the computer had more intelligence
it
would know that it will have to break again fairly soon so theres no point
accelerating to a higher speed but instead just keep coasting at the
current
one. No only would this be more comfy for the passengers but it would save
energy too.

How granular is the speed control on these trains? I read somewhere that
the Victoria line basically has Full and Half speed (as well as stop,
obviously). Is the Central line system more advanced?
