Ah, this is for a trip in December if that makes any difference to it being dead / things not open in August?

Not sure I like the idea of the late night train if it's dangerous though... I would be with my fiance and wouldn't want to put her in a risky situation.

I was looking on italiarail.com and although they don't have their schedule for December yet, on a Monday in November they have trains we could catch that would be early enough with time to spare to make it back for the return flight.
