Trenitalia ticket changed to train + replacement bus, but no notification?

Your current ticket is still valid. Just go with the flow. Regional tickets are often open tickets, good until validated. It is virtually impossible for Trenitalia to notify everyone who bought tickets, as many buy them anonymously out of ticket machines.

Thank you for the info.

Question: when I’m getting ready to head back to Palermo and I go to the Agrigento train station, I assume I’ll be able to find the buses fairly easily and that they’ll have signs, correct?

I am sure that would be correct. Remember, you are not the only one. Other people will be doing likewise.

We had a very similar experience in September…we had regionale tickets from Firenze to Lucca showing a direct trip (with stops butno change). The train stopped in Pistoia, and because the four of us were in the last car with just two other people, we didn’t notice that EVERYONE had left the train. I finally peeked out the door and found a Trenitalia employee who basically said, “Are you looking for the bus?” Huh? He checked my ticket and apologized profusely, called the bus and told them to wait for us. Because I had purchased the tickets several months prior to our trip, the changes (adding a new parallel rail line) didn’t show, nor did they show when I checked our tickets the day prior to travel. Our tickets were honored, as I’m sure yours will be, but it might be a good idea to check with a ticket agent at the rail station.
