I saw a cargo train derail in Rochester NY in the early '70s. Only moving 30 mph or so in city limits and cars were leaping straight up and coming down every which way. Having seen one in process, I'm even more amazed at the low number of deaths.
He couldn't remember what type of engine it was, and I think he said there weren't any serious injuries.
I knew a guy that was on a commuter train that was rammed from behind in a tunnel going into Boston. His injuries amounted to a dry cleaning bill for his suit from smoke grime and smell.
