They're not.

Thinking about this, could it therefore be that the bus bomb failed to

Once the perpetrator is identified, I wonder if he was seen on CCTV
boarding a train earlier on?

Green Park layout, in diagrammatic form:

------ running line

Platform layout is from CULG (thanks Clive) - note both have two distinct
platform tunnels, this is not indicating a central island.

Wrong word. Lines converge at both places and that seemed to be
important on the two Circle Line blasts.

You don't mean converge, you mean there's an interchange between
Underground lines. Tighten up your text!

Not going to happen. Currently cooking up something a bit more exciting...

Still on tenterhooks wondering what that could be. It all depends on
how long the Picc will be out of service. If we're talking MANY months
(and I just checked, and KX Northern Line was closed for 16 months
after the fire, so my guess is we're looking at a closure of 1-2
years), then maybe the 'bit more exciting' would be to replace the
trailing crossover at King's Cross with a facing one and let westbound
trains reverse on the eastbound line south of KX. Assuming the tunnel
profile can take it (possible either way; I don't exactly remember)
they could probably get that up and running, at least hand-worked,
within weeks.

Eventually they'd have to put the trailing crossover back, both because
facing crossovers are frowned upon when not strictly necessary and
because it would be a total pain to get stock off the Northern to get
to Acton Works if it was still there, but it would allow the Picc to
operate between KX and Cockfosters in the interim.

I don't know why you think that either. On a quick and non-rigorous
check, I make it 34 interchange stations within the approx. area of
Zone 1, and 23 non-interchange ones. Both counts are probably low as I
couldn't be bothered to check where all the boundaries are. However using
those figures, if the bombers were working on a purely random basis,
it is likely that two bombs would explode at interchanges (p=0.51),
but not that three bombs would (p=0.37). Which is in fact what happened.

Also, if you mean that because lines have an interchange, a bomb on one
must affect the others, you can see a layout of Piccadilly Circus he
http://www.geocities.com/Athens/Acro...069/ltpicc.gif which shows
the lines are completely independent, whilst Green Park is infamous for
the long distance between lines at the interchange.

Using the current map, I make it:

* 27 stations with interchange between lines
* 22 station on one line only
* 8 stations served by one LU line but also a mainline service
* 4 stations (Aldgate, Aldgate East, Edgware Road [subsurface], and HSK)
which are divergence points for subsurface routes
Euston Square, and High Street Kensington) which can be
* Euston Square, which is arguably a mainline interchange and arguably
not.

So of 62 stations, between 27 and 40 are "interchanges".

There is also CCTV equipment with cameras in all the cars on the
newer trains. This could possibly provide vital information following an
incident, especially when that incident is on the train or following the
trail of a suspect. However, On the Northern Line, a large percent of the
equipment is faulty and has been for a long while with no urgency to
rectify it, so it's unlikely that it would be of any help.

Given the importance for public safety of working CCTV equipment on both
buses and tubes, I should think there is a good case for bringing in
legislation to severely punish companies and individual managers who
fail to keep such equipment in full working order.
