Just walk up to the station and ask. However if money is really an issue for you you should probably be taking the bus instead of the train. Buses generally cost a tiny fraction of train fares in Italy. A bus from one end of a region to another might cost only a buck or two. Search around on google.it and use the translator if you can't understand Italian. Or again, just ask at the station.
