I plan to buy a Eurail pass that enables me to travel from France to Italy. I plan to buy the France-Italy Rail Pass, but I don't know whether I would need to buy an extra pass because from my research, the train will have to stop at Geneva, which is located in Switzerland.
Do I have to buy an extra pass for this purpose?
Edit: As I research further this train comes to my mind (TGV 9249). I think this is really what I really need; am I right?
