Yes it does: not very many people want to use the Circle-specific
bits.

A very large number of people want to go beyond Aldgate, though -
Tower Hill is a specific example (though perhaps education about how
Aldgate is only ten minutes' walk would help more). So maybe the
"backwards C" of the Circle Line has very high demand, while the
left-hand side doesn't.

Yes, this is part of the S-stock upgrade plans: 7-car S-stock trains
the length of current District stock will run all District, H&C and
Circle services.

Good, as the current 5-car (I think) trains run on the Circle are
completely inadequate.

Does anyone know how quick the acceleration of the S-stock is? I
think a lot more trains could be fitted into the existing track (thus
giving scope for an increase in Circle frequency even without a
decrease in other frequencies) if acceleration/deceleration and
average running speed could be brought up to the level of, say, the
Central Line.
