A regional train is called a Regionale, R or RV on smaller monitors.
The Full fare, the only fare available on the day of travel, is called BASE. Whenever you buy, rest assured that you can't pay more than BASE and that it's always displayed up to 120 day in advance.
All the other fares (Economy, SuperEconomy, A/R in giornata etc.) are discounted and have restrictions.
Note that if you buy on trenitalia.com and you miss a connection because of trenitalia you are always protected, discounted fare or not.
Thank you for this info!
You are welcome, but remember to time-stamp locally purchased regionale tickets before boarding.
If you forget and the train has left, look for the conductor. Don't wait for him/her at your seat.
there is a sort of family connection.
For ages italiarail has been the only authorized official re-seller of trenitalia based in North America and the only one who could sell capacity controlled discounted tickets. Now every re-seller can do it.
