The most common way to travel in Italy is train
Trains in Italy are convenient and relatively cheap compared with other European countries. The better train categories are fast and comfortable.
Trenitalia is the national train system that runs most services. Its privately owned competitor Italo runs high-velocity trains on two lines, one between Turin and Salerno, and one between Venice and Salerno.
Train tickets must be stamped in the green machines (usually found at the head of rail platforms) just before boarding. Failure to do so usually results in fines.
Italy operates several types of trains:
Regionale/interregionale Slow and cheap, stopping at all or most stations.
InterCity (IC) Faster services operating between major cities. Their international counterparts are called Eurocity (EC).
Alta Velocità (AV) State-of-the-art, high-velocity trains, including Frecciarossa, Frecciargento, Frecciabianca and Italo trains. with speeds of up to 300km/hr and connections to the major cities. More expensive than InterCity express trains, but journey times are cut by almost half.
