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

To neighboring countries yes, if there is a good connection. If there is a night train even further. However, the price should not be much higher than a flight and I want to change train as little as possible. Buying tickets should not be too complicated either. Unfortunately, taking an airplane is often easier in my experience. We need a true high-speed railway network across Europe. Something like the Shinkanzen.
