Especially when you account boarding, navigating the airport, having to show up at least half an hour before the flight, security checkups... All time-consuming tasks related to boarding the actual aircraft that you don't have to go through to hop on a train.
No, you have to run like crazy hoping not to lose the connection train, being stopped in the middle of nowhere without any information, stuffed into wagons without air conditioning and possibility to open the windows, cramped with more passengers than available seats, without any place to stuff luggage, out of order toilets,....
You get the same issue with connections whether you fly or take the train (I strongly avoid non-direct routes for this reason).
None of my train trips in Europe (Scandinavia, Germany, Switzerland) had the issues you mentioned.
In particular, the designers of the German ICEs seem to have realized over the past ~decade that people don't want to lift heavy bags overhead (especially if the compartment is too small), and that when the only other space to store them is the corridor, the corridor will be full of bags. They added dedicated luggage racks with enough space to actually fit your luggage.
Okay so fly to CDG in Paris and then enjoy the annoying train ride into Paris that takes an hour and leaves infrequently. How do you get to and from the airport anyway?
Many cities it’s a nightmare to get to the airport, whereas the train station is usually central.
German trains pack as much people as possible and occasionally you can consider yourself lucky if you manage to reach your seat, if the wagon is still available to start with.
Agreed. I'd definitely say if you're only travelling across one or two European countries, between major cities, rail is definitely the way to go. It's more comfortable, safer, you're infinitely less likely to get touched up by an overzealous security person, usually takes you right to the city centre that you're interested in, you don't have to worry about Ryanair trying to extort something out of you. You also don't have to worry about airplane mode and many railways provide free (if shockingly bad) WiFi, and many routes have reasonable 3/4G coverage.
> In any case, that was just an example, I am not doing Germany - Portugal by train, unless forced to do so. It is more than 24h.
That's the point, we need to expand the rail network to make longer distance trips shorter, more comfortable, and affordable. Flying can't continue to be the default option.
