ok, I called the trainstation and it is like this...
the train Frankfurt - Vienna on the 1th december would leave at 22.47 and arrive at 8.52 in Vienna.
the train Vienna - Frankfurt on the 7th december would leave at 20.28 and arrive at 6.02 in Frankfurt.
Is this ok? Also with the dates?
Each ticket is 29 Euro and 3 Euro to send the ticket to Finnland.
So all together 61 Euros.
The tickets can only be bought with a credit card. So if you want, you can send me an e-mail with your cardnumber and when it expires and so on. Or if you don't have a creditcard I can also just buy it with my one. As you like.

Just tell me, what I shall do. ;-)
