I´ve checked and I have to change train 2 or 3 times. How does it work?, I mean, do I have to get off in a certain station in the way and change to another train like if it was an underground?, do I have to wait until the finish of the line?, how do I get this info? because I only know the number of train for the moment and I would like to get lost XD.
I guess, if I book the tickets, I will get more info but I would like to know it in advance :)
Thank you very much!
