Not notice loud banging and violent shaking underneath you? You can sleep through that, with practice, but you will notice it.

It's actually rather quiet from the relatively sound-proof interior, and there is no noticeable shaking.

These aren't American trains.

I took those trains many many times, years ago. A lot of shaking and a lot of banging because that’s how they change bogies. The vibration spreads across the carriage’s frame from underneath. And no, those aren’t American carriages. They’re formerly East German.
