Trains are great for no more than 600km range trips. I live in Spain, and it's great to get into the train without doing all the procedures you do with a plane. I arrive to the station 10 mins before departure and I never had troubles. With airplanes I need to be there 1 hour before. Then you spend another 30 mins getting into the plane, following the instructions for just only 1h trip. The same trip Barcelona -> Madrid can be done without all the hasle and even faster than in airplanes, in addition, you arrive in the center of the city, much better connected than the airport, where you spend another half an hour to reach the city center.
In my experience, airplanes are worth once you talk about trips over 800km. Trips that you cannot do in less than 2 hours of train.
