Hello,
Thank you for your question. I am happy to see that the community is helping out by giving answers and suggestions as well. Yes, the scheduled for some routes are out but the trainline does not release all schedules at the same time. The closer to December the more routes will be open and available. Because the trainline Trenitalia is ran by the Italian government the schedules run 365 days a year and they stay pretty consistent to what the previous years schedule was. You can always look at the past schedules to get a good idea of what will be available.
