@albertcardona So true! And on top of that, it's often super hard to figure out where/how to buy the relevant tickets. You don't want to know how much time I spent on that. I actually wrote a blog with tips about this: https://mariekevanvugt.blogspot.com/2023/08/how-to-travel-by-train-in-europe.html
@mvugt
I am trying to go to Germany from the UK. It's really not far by any stretch of the word. The train connections between multi-hour legs are less than 20 minutes. Past experience indicates that's not enough.
I wish there was an integrated trans-European railway ticketing and scheduling system.
