The short answer
Between the big cities — Milan, Venice, Bologna, Florence, Rome and Naples — compare both and book the one with the best time and price. Comfort and speed are very similar. For smaller towns, the coast and the lakes you will need Trenitalia’s regional trains (or regional operators such as Trenord in Lombardy), because Italo runs only high-speed services.
Who runs what
| Trenitalia | Italo | |
|---|---|---|
| High-speed | Frecciarossa, Frecciargento | Italo |
| Intercity | Yes | No |
| Regional trains | Yes (Regionale, Regionale Veloce) | No |
| Network | Almost the whole country | Main high-speed routes and selected cities |
| Tickets valid on the other? | No — a Trenitalia ticket is not valid on Italo, and vice versa. | |
Main routes and approximate times
Fastest services, rounded. Both companies run most of these routes.
| Route | About |

| Rome → Naples | 1 h 10 min |
| Rome → Florence | 1 h 35 min |
| Florence → Bologna | 40 min |

Watch the station
Most trains use the main central stations — Roma Termini, Milano Centrale, Firenze Santa Maria Novella, Venezia Santa Lucia, Napoli Centrale. But some services stop only at secondary stations, such as Roma Tiburtina, Milano Rogoredo or Milano Porta Garibaldi, or Venezia Mestre on the mainland.
Classes compared
| Level | Trenitalia Frecciarossa | Italo |
|---|---|---|
| Standard | Standard | Smart |
| A bit more space | Premium | Comfort |
| First class | Business | Prima |
| Top | Executive | Club Executive |
For most travelers the standard class is perfectly comfortable on trips up to three hours.
When only a regional train works
Many favorite places are reached by regional trains, not high-speed ones — for example the Cinque Terre, Lake Como villages, Pompeii and many towns in Tuscany and Umbria.
- Regional tickets usually have a fixed price and no seat reservation.
- Paper regional tickets must be validated in the machines on the platform before you board. For digital tickets, follow the instructions on the ticket.
- Buy them at station machines, ticket offices or in the operator’s app.
Booking tips
- Book high-speed trains early. Prices change with demand; the cheapest fares sell out first.
- Compare both companies for the same route and time — one is often cheaper on a given day.
- Arrive 15 minutes early. The platform (binario) often appears on the board only shortly before departure.
- Keep big luggage manageable: there are racks at the ends of the cars and above the seats.
- Check for strikes before every train day — see our train strike guide.
