Europeans, do you take the train to travel to other countries?

As a French living in Germany, I often take the train to visit some friends/family. I would say it's working well from Frankfurt to Lyon or Frankfurt to Paris and not too expensive if you have a Bahncard and you can plan your trip in advance. But IMO, it the least we should expect from 2 neighboring countries.

I'm very excited to see the resurgence of night trains though, I love this mean of transport in particular!
