I will arrive Milan on Decebmer 26 afternoon, and plan to take night train to Rome.
How can I make a reversation for sleeper or couchette on Night Train from Milan to Rome.

Tried Trenitalia web site, really confuse and could not let me log in, even could not find the price of sleeper or couchette. Also the English version of Trenitalia is not working.

How can I call Trenitalia from outside Italy. I could not dial their gingle national number 89.20.21 from North American.
