Ciao @ccpking and welcome to our community! We are a partner site of ItaliaRail.com where you can purchase Trenitalia tickets in English and we provide English-speaking customer service.

We publish notifications when train schedules are released. They typically come out twice a year for the following six months or so. If you go to our page here - Train Timetables -and click \"Follow\" you'll receive an email notification when we receive word that Trenitalia has released bookable routes.

At the current time I'm seeing schedules already released for the Rome Termini to Venice route in September. For example, I put in a mid-September date, September 12, and got bookable results as shown below:

So maybe give a try on ItaliaRail and see if you manage to find what you're looking for.

Feel free to check back here in the community if you need any direct assistance with booking. I'll tag our Travel Experience Manager @mirai_hanna in case you would like one of her agents to get in touch with you directly via email to help you out, you can just reply to this thread and she'll get notified.

How do I buy tickets from Rome to Venice round-trip I’ll be there in September
