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.

I can see you are (rightly) sceptical. But the OP has some antisceptic,
it seems.

I was taught at school that pretty much anything can be an explosive if
powdered finely enough and mixed with air. Custard powder and paint are
particularly good at demolishing the factories where they are made.

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.
