Our guide to traveling Italy by train: Trenitalia vs Italo, the high-speed network, classes, booking, rail passes, regional trains, strikes and scenic lines.
Italy is one of the best countries in Europe to travel by train. A high-speed line runs the length of the country from Turin and Milan through Bologna, Florence and Rome to Naples and Salerno, with branches to Venice, and two companies compete on it: Trenitalia, the state operator, with its red Frecciarossa trains, and Italo, a private operator. Rome to Florence takes about 1 h 30, Florence to Venice about 2 h 05, and the trains leave city center to city center, often several times an hour.
For the classic first trip (Rome, Florence, Venice), the train is faster and calmer than driving or flying. Below is how the network works, which operator and class we book, how passes compare with tickets, and what to know about regional trains, strikes, luggage and accessibility.
| Trenitalia (Frecciarossa) | Italo | |
|---|---|---|
| Owner | state group Ferrovie dello Stato | private company |
| Network | high-speed lines plus Intercity and all regional trains | high-speed lines only |
| Classes | Standard, Premium, Business, Executive | Smart, Prima Business, Club Executive |
| Accepts rail passes | yes: Eurail with a paid reservation, Trenitalia Pass with a free one | no |
| Cities served | the whole country | the main cities, including Rome, Milan, Florence, Venice, Naples, Bologna, Turin, Verona, Salerno |
The two are equivalent in speed and comfort on the main axis. We book whichever has the better timing and fare for each leg, and sometimes mix them on the same trip. Two practical differences: only Trenitalia serves regional lines like the Cinque Terre and most smaller towns, and only Trenitalia accepts passes.
Think of a long spine with a few branches:
| Route | Fastest time | Our guide |
|---|---|---|
| Rome to Florence | about 1 h 30 | Rome to Florence by train |
| Florence to Venice | about 2 h 05 | Florence to Venice by train |
| Rome to Venice | about 3 h 50 | Rome to Venice by train |
| Milan to Venice | about 2 h 25 | Milan to Venice by train |
| Rome to Naples | about 1 h 10 | Rome to the Amalfi Coast |
Station names matter. Rome's main station is Roma Termini; Florence's is Firenze Santa Maria Novella (S.M.N.); for Venice, get off at Venezia Santa Lucia, on the Grand Canal, not Venezia Mestre on the mainland; Milan's is Milano Centrale; Naples' is Napoli Centrale. Some trains stop only at Roma Tiburtina or Firenze Campo di Marte, so we always check the station on the ticket.
On Trenitalia's Frecciarossa, Standard is a good second class, Premium adds a little more space, Business has larger leather seats and a quiet area on most trains, and Executive is a small car with a handful of large seats and a meal served at your seat. On Italo, Smart is the base, Prima Business is first class with leather seats, extra legroom and a snack and drink served at your seat, and Club Executive is the top class, with extra-wide seats and catering at the seat.
For most of our travelers we book Business on Trenitalia or Prima Business on Italo: wider seats, calmer cars and more room near the seat for a medium suitcase. The difference is often modest when booked early. Executive is a treat on a long leg such as Rome to Venice.
Two passes exist in 2026 for travelers living outside Italy:
Our view: on a typical trip of four to six train legs booked a few months ahead, individual tickets usually cost about the same as a pass, with more flexibility in choosing Italo or Trenitalia. A pass helps with last-minute bookings or many long legs. We compare both on each quote.
Regional trains (Regionale and Regionale Veloce) serve the Cinque Terre, Lake Como, Pisa, Lucca, Siena, Verona and hundreds of towns. They have fixed prices, no seat reservations and no classes on most lines, and they are often crowded in summer.
The one rule to remember is validation. A paper regional ticket must be stamped in the green and white machines on the platform or in the station before boarding; an unvalidated ticket can mean a fine. Digital regional tickets bought from Trenitalia's app or website activate automatically at the scheduled departure of the chosen train, so no stamping is needed, but they are valid only for that train. We buy regional tickets for our travelers in advance and tell them exactly which one is which.
Italian rail strikes are frequent and always announced in advance, usually a week or more ahead, on the Ministry of Transport's strike calendar and in the train companies' news. For regional trains, a minimum service is guaranteed on weekdays from 6 to 9 a.m. and from 6 to 9 p.m. For high-speed and Intercity trains, Trenitalia and Italo publish a list of guaranteed trains. When a strike falls on one of our clients' travel days, we move them to a guaranteed train or arrange a car, and we warn them as soon as the strike is announced.
Italian trains have no weight limit for luggage in practice, but you carry your own bags: there are steps up into most trains, and porters are rare. Large suitcases go in the racks at the ends of each car or behind the last row of seats; smaller bags above the seats. Italo sets a size limit of 75 x 53 x 30 cm for bags in its Smart class. With two large suitcases each, we suggest one checked bag per person and sending the rest ahead, or a private transfer between stations and hotels in Venice and on the coast.
Italy's rail infrastructure company, RFI, runs a free assistance service for passengers with disabilities and reduced mobility, the Sala Blu. In 2026 it had 16 Sale Blu coordinating assistance in more than 380 stations, with staff and lifts to board and leave the train. You book by phone (+39 02 32 32 32 from abroad), online, through the SalaBlu+ app or in person. Notice required: at least 1 hour at the main "fast" stations for daytime trains, and 12 hours at other stations. Frecciarossa and Italo trains have wheelchair spaces with accessible toilets, which must be reserved. Older regional trains can have high steps; newer ones are level from raised platforms. Our guide to wheelchair accessible Italy goes further.
Our Rome, Florence and Venice by Train in 10 Days is built entirely on high-speed trains, with Business class seats reserved.

Neither is better on the main high-speed routes: speed, comfort and prices are similar. Choose by timing and fare for each leg. Trenitalia also runs the regional trains to the Cinque Terre, Lake Como and smaller towns, and it accepts rail passes. Italo often has competitive fares between Rome, Florence, Venice, Milan and Naples.
For high-speed Frecciarossa and Italo trains, yes: fares rise as seats sell, and popular trains fill up in May, June and September. We book three to four months ahead. Regional trains have fixed prices and no seat reservations, so tickets can be bought on the day, but paper tickets must be validated before boarding.
Usually not for a typical trip of four to six legs booked a few months ahead. Individual tickets cost about the same and let you use Italo, which does not accept passes. The Trenitalia Pass, from €139 in 2026, and the Eurail Italy Pass make more sense for last-minute travel or many long journeys. Pass holders still pay or book reservations on high-speed trains.
Strikes are announced in advance, and a minimum service runs: on weekdays, regional trains are guaranteed from 6 to 9 a.m. and from 6 to 9 p.m., and Trenitalia and Italo publish lists of guaranteed high-speed trains. We check the strike calendar for every client's travel days and rebook on a guaranteed train or arrange a car when needed.
