It might fry all the GPS sats too though. Southern region
trains won't know if they are at a 'short' platform :-)

They use GPS to decide if the rear N coaches of a 12-
coach train are next to a patform.

Mind you, people managed with the old slam door trains.

and the sun shoves its massejections in another direction as it did a couple
of weeks back then you have no immediate issue.

I can say this though at the moment the propagation over short distances of
low frequencies in the mornings is crap, and the noise is bad from the
ionosphere.
Nobody really knows the way the two processes in the sun interact to add or
diminish the solar cycle. Some may suggest by a rule of what happened when
things are as they are now, but I cannot say I'm impressed with accuracy.
With a bit of luck it will fry Musks satellites and deorbit them.
