The Italian train system is pretty friendly to cyclists. Alot of the regional trains have a designated car for bikes. You must buy a bike pass, about $5.00 for the day, along with your ticket. I took the train from Florence (Firenze) to Bologna, then Bologna to Venice (Venezia), the Venice to Trieste.
