I think there are two issues being confused here. There's no reason to
doubt that TPTB at LU spent the first 20 minutes (or hour or however
long) thinking a power surge was responsible for the incidents.
However, the public were told for *hours* afterwards that it was just
a power surge. For the whole morning, news organisations were
variously reporting up to 7 explosions on the Underground and up to 3
on buses, while being kept completely in the dark by official sources.
There was a definite witholding of information, be it at the behest of
LU, or the security services, or whoever.

Thank you.

First of all, how can a 'power surge' cause a major explosion on one
train but not all of the others fed by the same substation? And there
were several trains. So, a system-wide 'surge'? Again, why would most
trains be unaffected?

And just how would the power supply apparently 'surge'? Maybe the grid
voltage could have shot up suddenly, but how? Wouldn't other
recipients of electricity (including National Rail electric services
in the London area) have noticed? And wouldn't the power supply, and
the trains, have had some protection?

The thing is I can't put my hand on any sources ATM, but I'm certain
that the authorities have said that the story was fabricated. And why
not?
