Senior discount on Trenitalia?

If you drill down into the details on the website I think you'll find that the discount is for EU only - there's a card that has to be applied for and displayed on request by the ticket checker.

Thank you, Bob. I did not see that detail, but kind of expected that to be the case.

Trenitalia used to sell a senior-discount card that wasn't limited to EU citizens. Is that no longer the case? I have bought such cards in Spain, France and the UK recently.

Here's the English version of the blurb on the Trenitalia website:
"Are you a member and are you already 60?

With the Senior offer you can travel with variable discounts, between 30% and 50% compared to the full Base price, depending on the advance of the purchase, on all national trains and in all service levels, except for the Executive level.

You can purchase the offer until midnight of the second day before the train departs, online, at the ticket offices, authorized travel agencies, self-service or by calling the Call Center (paid number).

The number of seats is limited and variable, depending on the days of the week, trains and class. You cannot combine the offer with other reductions."

Which was confusing enough for me, especially the part about only being able to reserve seats at the reduced rate 2 days in advance, that during our recent visit to Florence in June I asked for clarification at the ticket kiosk at the station where I was informed that it was EU only.

Even if you can't get the senior discount, very often if you book as soon as the tickets open up, they offer discounts. So, not sure how soon you're traveling, but that might help your budget.

It does sound as if they intend not to allow the discount the day before and the day of departure. I haven't run into that before.
