I hear that the H&C could be 2 months before it is back in order (worst
case because they don't know the tunnel status until the police vacate
site and Piccadily is anything up to 8 months if the tunnel needs a
rebuild - comments?

Well the TfL press release at
http://www.tfl.gov.uk/tfl/press-cent...t.asp?prID=428
says they expect to have a full service running on the Circle/H&C five days
after the police have finished their investigations. I don't think they
would say that unless they were confident there had been no major structural
damage.

If the reports today (that the explosive was mostly Acetone Peroxide) are
correct, then it would be unlikely given the damage to the train that
any serious damage was done to the tunnel.

Since the rest of us aren't the explosive experts that you are, David,
perhaps you can explain that remark?

That explains the chemistry, but says little about what type of damage
it might cause, and why. There were some early reports that the type of
explosive could be guessed from the way that victims' clothes were
"blown off" and other contemporary descriptions of the sound and light
accompanying the blasts. Perhaps these are what were being referred to?

A bit worrying that I have both main ingredients, in very small
quantities, at home. Acetone is a useful solvent for fibre glass resin
and hydrogen peroxide is an antisceptic. Looks as though I might be
using alternatives from now on.

Lots of things are flammable and explosive if converted to a fine
spray. Petrol can be used as an explosive and so can flour! Its not
worth worrying about.

In order to make Acetone peroxide you also need a mineral acid (to
act as a catalyst) and keep the mixture cool to stop unstable
products forming. Also helps if the Peroxide is in industrial strength
(at least 20 volume), as you don't get much product otherwise.

Not that I want to encourage you to do this. Acetone peroxide is
almost as unstable a high explosive as Nitrogen triiodide.

And I've been using some sulphuric acid drain cleaner this afternoon...

I can see the black helicopters closing on our little cell already...
