Given that the exact same question is the current top post but for driving instead of transit, I feel this question was needed.
My answer: I saw some guys hooking up a Raclette Grill to the outlet in an otherwise empty German intercity rail waggon. They had it unpacked in one of these 4 person seats with a small table. No idea if that could work or if draws too much power from the board net. I just headed on to the next waggon.
I want to live where the fast passenger train takes me to the next large city 150km away like it’s easy. I could totally get used to riding an hour to get to the hot springs; it’d be a great ‘down’ weekend.
there are some tradeoffs
that train used to have peak speed of about 150km/h on that route maybe it’s a bit faster by now. these five stops are in three cities, and there’s 250km-ish distance between them. (and all built for EU money) by that 30 minute mark it started slowing down and was something like 60km away from city
