What are you going to do with a hijacked train? The moment you hijack it they’ll just shutdown power. Hostages? Good luck there are like 30 carts on the train all of which have window break tools and emergency door open tools.

Look at Germany or France. High speed trains are everywhere and there is no ID requirement beyond maybe a ticket check if you’re unlucky.

What do you mean there's already been terrorist attacks on trains but nobody really cares because it's a train.

one terrorist attack

Had one in 2004, didn't result in security theater (though its mishandling did almost certainly result in the ruling party losing the election).

We don't even have that stuff on flights here (at least within Schengen). On my last 4 flights I had to show my ID once and the security check is just standing in the scanner thing for a second.

Has to harm billionaire asset to matter. Killing the rest of us is a game billionaires already enjoy and would applaud the Panem twist of a visiting team

in china there are similar security checks for high speed rail

I'm sure they'd finger you if you asked nicely, and have showered recently.
