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

6 car - but of only 16m so seems quite short. A stock is 8 x 16m, D stock
is 6 x 18.3m

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.

The end game in 2018 with S stock and new signalling is shown in that LU
document posted a couple of weeks back:

32 tph peak on the north (8 H&C, 8 Circle, 16 Met) and south (24 District, 8
Circle) of the circle. So 8 tph Adgate to Tower Hill, 16 tph Edgware Rd -
Baker St.
