Except the trains don't have an "under the seat", in that sense. Some of
the seats have cushions which can be lifted up, but you couldn't do that
without attracting *lots* of attention (and many, perhaps not all) are
fixed in place with cable-ties as part of a years-old security
precaution.

I saw a post saying the KX stop is the only stop on the Circle Line
where trains in both directions are separated by an central island
platform. All (most?) of the other stops have platforms on the
opposite side of the train. That means the doors that open at KX are
not used for the other stops. This might make it possible for someone
in a crowd to leave a smallish package by the doors that open at KX and
no one would notice until things had thinned out significantly.

The question I have is how far would you have to travel in either
direction from KX before the doors that open at KX would be used again?
Would you get as far as Edgware and Liverpool? Were the blasts on the
204 and 216 on the correct side (KX platform side)?

If so, then dropping the package near the door while the train was at
KX might be feasible without attracting attention. That would obviate
any "babysitting" and means the perp never has to leave KX.

I was also wondering .... how often at KX during rush hour do you see
Circle Line trains in both directions at the station at the same time
or nearly the same time? Is it something relatively common? If it is
then waiting for such an occurance to start the process would minimize
the time planting the first two bombs and gives you as much as 10
minutes before you have to be at the Picadilly Line.

If all that is true, then you really only need one person because you
can do everything in a walk.
