No exact numbers from me. However, I suspect that on certain lines
at certain times there are more trains than stations in the central
area (a term I use in a vague way). That may also be the case
outwith the central area, where the distance between stations is
much greater.

The Circle Line IME is likely got more trains than stations during the
rush hour due to "intruders" from the Met, District and Hammersmith
and City although the effect will be lessened to some degree when
clearance is required by use of various sidings/extra platforms or
escape routes to other lines. The central parts of the Northern Line
are possibly another candidate for having more trains than platforms
(rather than stations) during the rush hour but I suspect the "excess"
trains (if any) do not amount to more than a few.

The Circle Line itself runs only every 8.5 minutes, thus allowing room
for the "intruders". The timetabled interval between trains of the
combined service is not less than 2 minutes, whereas the stations are
generally 1.5 to 2 minutes' running time apart. (Farringdon to King's
Cross is the main exception at 3.5 minutes.) So there are, on average
anyway, more platforms than trains.

I think that generally in the central area, trains run at 2-minute
intervals or more, and stations are 2 minutes apart or less.
