It's ironic that this should happen in an area without a single
electrified line.

Not really. As part of any electrification project is protection/
immunisation of sginalling circuits from stray power, it is arguable
that the signalling systems in electrified areas may be more robust
and resistant to surges such as this. A surge taking out the emergency
genny does sound farcical.

Yet more evidence for "an incompetence of engineers" being the
appropriate collective. They could have hot-wired the generator into
service, or even just done the job properly to begin with so it works
as intended. If this lot had been around in WW2 we would have lost.

Glad to see that somebody besides me thinks this way about this type of
issue.

Where was the backup?, money used towards some directors bonus!?

It was probably a stray gust of wind that started the turbines going
unexpectedly and tripped the whole grid :-)

NOBODY expects windmills to generate!

Having backup genset running is little use if the surge has taken out
fuses and/or power supplies in the kit that the generator is
supplying.
