Actually for shunting that is normal. Derailment during shunting operations is a frequent occurrence and there are derailment facilities where shunting can occur, which get activated every time a train passes. What is rare is having an actual train derail.
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.
Huh? I'm answering to a whole lot of comments, not just yours, you're not special ;)
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?
