I'm a bit confused by what I'm seeing on the Trenitalia site so want to check before I purchase tickets. We want to go from Lecce to Napoli Centrale and there is a route offered with 1 change. A Frecciargento train goes from Lecce to Caserta, and then the next leg is listed as a Regionale
However in the area for the Regionale train it says
To travel, you must check in after midnight on the day of travel and before the scheduled departure of the train selected at the time of purchase. Servizio regionale 2 Classe a prenotazione
I thought Regionale trains never sell out because they don't have reserved seats. And the Frecciargento section, which I think is a reserved train, doesn't have this text. For this journey what will we need to do in order to take these trains? Log onto the Trenitalia site and check in somehow?
Also the connection time in Caserta is 9 minutes. Does this seem ok?
