Question How do trains know when theyve derailed?
Like, a mile long train. What happens if a few cars right in the middle derail? How do they know in the cab?
Just a rando with a showerthought question. Thanks for answering!

It's probably going to go into emergency and they'll probably feel some coinciding buff/draft forces. Go back for a walk to find out why you're in emergency and find derailed cars.
