I will be traveling to Spain, and noticed that I can get a train ticket at a discount if I buy online now. I started filling the form, and they wanted to know lots of data, including an ID number(!) and my full address, even though I chose to buy without a registration.
This made me stop and think. Maybe they need my address so they can send me my ticket per snail mail? This would be unfortunate, as I will have left long before a letter from Spain arrives. But until a few years ago, this was the way I had to buy my online tickets in Germany - order them and they came in an envelope - so who knows, maybe the Spanish railway still hasn't changed to electronically delivered tickets?
I don't speak Spanish, so if the delivery method is explained somewhere on the site, I can't find it. Does anybody know if I can buy the ticket online and print it right away?
