Agreed. I don't think trains are really good at speed yet relative to costs. They are however good at comfort if given the chance. There is less of a space and weight premium. Noise and vibration can be much lower. And a medium speed train they can still go twice as fast as car.

I wish someone would take the idea of a business or first class flight, without the luxuries and inflated cost, and put that on a modern medium speed train. Something similar to this seat layout: https://liveandletsfly.boardingarea.com/2018/02/08/swiss-777...
