This is true. And sadly the big state monopolies have been lobbying against the airline like system of bookings. They don't want to be responsable for connection like airlines are. And they don't want to compete on a level bases either. They don't want open ticketing information.

The EU approach to rail improvement is incredibly flawed.

And all the different monopolies have their own dumb as opinion about things. French system is run by a bunch of airline manager idiots. German can't make their IT work for shit. And so on.
