Fast trains (Frecciarossa, Frecciaargento) are, naturally, faster and more expensive. For some trips a slower train (Intercity or Regionale) may be a better buy.
Tickets on regional trains will need to be validated at the validation machines before boarding the train.
Know the station where you want to get off. Large towns have several stations.
Find the train by time and the train number. The boards at the train station will list the final destination of the train, which may not be the student's destination.
Tickets on fast trains and inter-city trains have assigned seats. The car and seat number will be on the ticket. Regional trains have no assigned seats or times on the ticket and therefore must be validated.
