My situation is:
1. I travel from Vicenza to Milano on the Italo high-speed train. The train leaves at 9:45 and arrives in Milano at 11:26.
2. In Milano I want to board the Trenitalia train to Spezia that leaves at 12:10.
This will happen on Monday.
In my experience, high-speed trains in Italy are likely to be delayed. I have already been traveling on an Italo train, which was delayed for 40 minutes (due to the high-speed line jam, as I heard in the announcement) This was Friday. Right now I have boarded a train that was delayed 10 minutes, it's Saturday.
My question is: will I arrive in time to Milan to change trains on Monday or should I not consider doing so?
Additional question: do these high-speed delays have anything to do with Ferragosto's vacations (which was recently in Italy) or just the weekend?
