You might find some information about night trains in the ticket office of your train station. I think that you have to book before, even if you have a Global Pass.
About the timetable, you should look into the Thomas Cook European rail timetable. It's really complete and it could tell you between which cities you could have night trains.
See ya' (on the road maybe).
thank you for your answer!! :)
For Italian part check the trenitalia website. http://www.trenitalia.com
I just checked and found there is a train from Roma to Venice.
Departing time 22:36
Arriving time 5:26
Cost 40.50 Euro
From Venice to Ljubljana there is only one train daily which is at 21:20 and arrived there at 1:41 am costing 25 euro.
I hope this would help.
Thanks for your answer. Yeah, I considered taking the menmioned night train from Rome to Venice.
If I travel with the Interrail pass, do I have t pay the full 40,50 € or would I get it a bit cheaper? Dies anyboday know that?
I have no personal experience but I guess like other fast trains in night trains too u have to do reservation which will cost around 10 euros at least. But definitely it will be cheaper with the Interrail pass.
I just took this (a little further though, to Zagreb)
I think for you, you are estimated to get off around 1 30 am, so maybe it won't be so bad. We boarded at 9 30, the seats did not recline at all, the lights stayed on the whole time and the AC was on full blast. Definitely plan on bringing a sweatshirt no matter how hot it is outside. Also, the ticket people and border control stop for a very long time frequently, so plan on being a little later than expected. A night train is a night train, so I'm not really complaining, but I have been on much nicer ones-good luck. It won't be so bad since you are doing the shorter trip, just make sure you have someplace to go as you will probably get off in the middle of the night.
