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

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.


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.

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

Two and two (in service), I thought?

I thought the W&C had two trains and two stations.

So where are there three platforms (or are you counting one at
Northumberland Road?)

But not more trains than platforms. Of the five trains, four are required
to work the peak service; the fifth would be in the depot beyond the
platforms at Waterloo. There are two platforms at each of the two termini,
so every train could get to a platform.

Just out of interest, how exactly does this work? I can't help
feeling that there are usually more trains on the system than
there are stations, and that therefore some trains get stopped
between stations. Do they detrain people in the tunnel and get
them to walk along to a station? Or do they hold trains in the
tunnel until the train ahead has been emptied and shunted forward?

I don't know exactly how it works, but I think that there are more
trains than stations only in your imagination. I am sure that some
body will be along in due course to give us the exact numbers.

On the Victoria line there are 15 stations or 31 platforms and 37
trains during the peaks.

I think there are 16 stations on the Victoria Line - but your point is
taken.

IIRC at least in the peaks the W&C has 4 trains in service. Normally all
passengers alight from a loaded train each time it enters a platform, and at
Waterloo the train runs forward into the headshunt/depot in order to
reverse.

Presumably after the Code Amber evacuation, on other lines trains run
forward ecs to a depot, allowing a following train to enter the same
platform to evacuate.

No. Four trains and, for the peak service, six drivers.

The numbers vary. The Victoria Line has a peak of 38 trains for 16
stations and 33 platforms. Overall, the current peak services (pre 7th
July) involve:

Bakerloo: 32 trains (31 in the evening peak)
Central: 72 trains
Jubilee: 51 trains (see note)
Northern: 91 trains
Piccadilly: 76 trains
Victoria: 38 trains
Waterloo & City: 4 trains

Circle + H&C: 30 trains, plus 2 standing spare
District: 77 trains (67 D stock, 10 C stock)
East London: 6 trains
Metropolitan: 45 trains, plus a half train on the Chesham shuttle

[In the morning peak, one Jubilee train comes out of service shortly
before the last of the 51 enters service.]

Do they detrain people in the tunnel and get them to walk along to a
station? Or do they hold trains in the tunnel until the train ahead has
been emptied and shunted forward?

The latter is more common, I believe.
