So I want to buy the 4 days in 1 month promo, but I don't really understand how I can check which trains and connections I can take. This is the first time I´m going to buy one and I wanted to do Madrid (im here right now) , Hamburg and finish in Paris, does anyone know how I could make this? hahaha like where can I see the trains? I just find the railway map but that's it.
any help would be awesome
(ps, I could take another bus or something plus I have the 4th destination which im planning to use depending on how I can get to any of this cities)
