The Trenitalia electronic ticket

Ticketless is the purchasing solution that lets you board your train without having to pick up a printed train ticket. It operates for all trains both in 1st and 2nd class as well as for the Couchette, Wagon Lits and Excelsior services. 

Ticketless tickets can be bought conveniently on this site, by calling the call center ((+39 06 68475475) or from the certified travel agencies- thus avoiding waiting times for picking up at the self-service tellers or for buying at the desks.
