i am going to be going round europe in the summer with some friends we are going to buy an inter-rail ticket, but i was wondering how much time should we leave for traveling how long does it take to get from paris to italy by train for example.
If you take the TGV then I think you can make it in about 15-20 hours. You do have to pay a supplement for that train with the interrail ticket though.
Use this website for train timetables throughout Europe. You can look for any route within europe.
