[February, 2011] I went to Nice from Milan by train.
It took about 5 hours.
I was expecting a new fast train like the Red Arrow, but in fact it was an old type with compartment seats.
It had a good old travelling atmosphere.
6 people in the room once started talking, they never stopped, so there was not a moment of sleeping for me.
You would expect one train goes all the way, wouldn't you.
I felt somewhat an invisible fence between the countries.
