Effective today August 1, 2016, 'Regionali' Trains tickets are no longer valid for usage for 2 months.
From now on, when you buy a 'Regionale' train ticket you MUST SPECIFY your intended TRAVEL DAY in addition to the destination.
You will be able to use the ticket and travel ONLY on the specified Travel Day (by Midnight).
On the Travel Day, you must complete your trip within 4 hours from the time you validate the ticket at the stamping machine. If the 4 hours expire while you are still on board traveling on the train, you will still be able to reach your specified destination without penalty.
If you need to change the Day of Travel, you can do so ONLY ONCE by MIDNIGHT of the day before.
These changes were enacted today to avert fare evasion, since many passengers do not validate the tickets and re-use them on subsequent days.
