Solar storms could affect train safety by glitching railroad signals
https://www.space.com/solar-storms-railroad-signal-train-safety

"The study modeled two United Kingdom railroad routes via computer: the
Preston to Lancaster section of the West Coast Main Line, and the
Glasgow to Edinburgh line. (These tracks are among those that use 50,000
signaling track circuits controlled by electricity between rails.)"

Are we still using voltages between the rails as track circuits on the main
lines? Surely by now they're using some kind of digital code!

I can’t help think there might be a unit missing there - 50,000 track
circuits seems quite a hight number.

Axle counters are gradually replacing track circuits, but they're not without problems, either.
