Im what context it is normal to derail a train to avoid a crash with another one?
More often than you think.

Especially when the train to be derailed is slow-moving or a freight train or runaway.
As I don't know whether you are referring to an actual train, or just use that as a term for moving railway cars, the answer to your question could be either yes or no.
You are acting like a good politician servant. I am bringing facts to the conversation while you try to derail it.
I'm not angry at you or your comments, I'm mad about misinformation and opinion-pieces lacking nuance though, that I can confess. I have no party, I purposefully don't vote in the nationwide elections, only in local elections.
Anything else you'd like to know about me? Or we're good-to-go for second date already?
