It can be a bit of a mess with different tickets and stuff I've heard

@Servais I'd love to do this once, but this is not practical at all where I live in order to do it more often, because I live in one of the countries marked with a shade of red on this map (in S-E Europe). And that is not taking into account various incidents that can occur with the locomotive and/or other rolling stock.

Train travels inside the country are indeed doable, and many people take them, but the speed is so low that for longer distances it is rather more feasible to travel by plane in a couple of hours than take one full day for each trip.

One of the coolest is from Copenhagen traveling. The train goes on to a ferry, then you get off the train, go grab a beer and enjoy the trip then. get back on the train and choo choo to Germany.

Not really. I take a bus though.

I used to love going to london from brussels. Not much opportunities these days but I would with pleasure.

Did it once but probably not again unless I can’t drive for some reason, like old age. I just love the freedom to be spontaneous about routes and schedules.
