We left Como via the regional train; it took us back to Milan Centrale. We waited awhile in Milan for the track announcement (at which point there is a mad dash to the train, then down the platform for the right car). I saw a fair amount of mask wearing at the terminal. On boarding the Frecciarossa (fast) train we got upgraded to business class because they'd substituted our car with an upgraded car. We enjoyed roomy reclining leather seats and free drinks as we watched the countryside whiz by.
We arrived in a foggy, atmospheric Venice.
