Freccia Rossa (High speed train) covers Milano to Bologna in 59 min. I timed it in 2010
+ 1 on Hotel del Borgo if I remember correctly I walked there from the factory
The hotel is directly across the street from Ducati Energia, make a right Via Antonio Cavalieri Ducati and then walk about 1/4 mile and that's the entrance.
We never took the train, I completely forgot about it. Having a car is actually very easy to get around and the Autogrills are awesome.
