I have bought my return ticket from Florence to Naples 3rd June but I want to deviate a bit. ( Iv'e already changed my date OK but it is not a ticket I can cancel and at Eu 112.0 I can't just not use it) ). Now I would like to go off to Arezzo and Perugia for a few day first.
I want to avoid having to go back to Florence to get the train I have the ticket for ie; NO 9527. I can't find the train route on line for no 9527 so I don't know which station I have to go to to connect with it. It would seem to be Chiusi or Orte but I need to be sure. It's easy to find all the stops on regional trains but not the Frecciarossa????
You want to pretend to be buying the ticket you have, by entering the Florence departure time on a train to Naples. You should see a few trips, one of which will be 9527. Click on a word like Journey Details. It should expand down and reveal all the stops and their times.
We have to hope that someone who knows more than I do can post that your entire journey remains valid if your ticket is NOT scanned by the conductor near Florence. An air ticket would be cancelled if you did not board the first leg of a trip. Many premium rail tickets are booked like air tickets nowadays.
Train No 9527 is nonstop between Firenze SMN and Roma Tiburtina, so that is where you would need to pick up the train. Seems like going back to Firenze SMN will be your best option. Info is at www.trenitalia.com, click on "Details" on the train listing.
“and at Eu 112.0 I can't…”
I am sure you meant €112 EUR

Ditto to what Sam said. According to the info on 9527 per the Trenitalia website (click "Details") that train is non-stop between Firenze SM Novella and Roma Tiburtina so you can't just pick it up somewhere in between.
The journey shown, per random dates, is:
Firenze SM Novella: 12:14
Roma Tiburtina: 13:40-13:43
Roma Termini: 13:49 - 14:00
Napoli Alfragola: 14:56 - 14:58
Napoli Centrale: 15:12
I am assuming you are using the Trenitalia website?
