Trains in Italy: A Practical Guide to Italian Train Travel

Italy’s rail network is one of the most comprehensive in the world. It connects the entire mainland as well as Sicily, and integrates seamlessly with wider European rail systems. This means travelling within Italy by train is simple, but so is arriving from or departing to neighbouring countries.

In addition to long-distance and regional trains, several Italian cities also operate metro or underground networks. These provide fast, low-cost train transport within urban areas and are used daily by both locals and visitors.

This guide will help you understand how Italy’s train system works, how to book tickets, how to use high-speed and regional trains, and how to navigate metro networks in major cities. Below I’ll cover:

I’ve used Italy’s trains to explore the length and breadth of the country since my first visit here with Sara in 2013. If you’re new to train travel in Italy, these three tips will make a big difference:

For all standard train journeys, excluding metro networks, I strongly recommend booking train tickets early. Reserving your tickets weeks or even months ahead usually means better prices. It also guarantees you a seat on trains that require reservations, as Italian trains are not overbooked in the way UK trains often are. Booking train tickets in advance also saves time on the day of travel, avoiding queues at ticket desks and machines.

Aim to arrive at your train station 30 minutes to one hour before departure. This gives you time to find the correct platform, purchase tickets if needed, validate them where required, and grab refreshments without rushing. This is also relevant if your journey involves changing at stations – pace yourself during train travel and allow yourself some buffer time in busy stations.

Italy’s trains are generally reliable, but delays can still happen due to strikes, weather or timetable changes. Building flexibility into your plans helps reduce stress. Where possible, consider flexible tickets that allow changes without heavy fees.

The Italian railway system is built around a dense network of main lines and regional services. Most trains run frequently between main Italian cities, while regional trains fill in the gaps, connecting smaller towns and more rural areas. At a high level, trains in Italy fall into four main categories:

• High speed trains on dedicated high speed lines
• Intercity trains linking major cities at moderate speeds
• Trenitalia regional trains serving local routes
• International trains connecting Italy to neighbouring countries

Most trains are operated by Trenitalia, Italy’s national train company, alongside private operators such as Italo and regional providers. All of these I cover in more detail below.

Italy’s high speed rail network is one of the most developed in Europe. Fast services operate on purpose-built high speed routes linking the country’s main urban centres.

The fastest trains in Italy are Frecciarossa trains and Italo services. These trains reach a maximum speed of up to 300 km per hour and connect cities such as Milan, Florence, Rome, Naples and Bologna in significantly reduced travel times.

The most popular train connections/cities where you can take high speed journeys are as follows:

• Turin – a major destination for connections within northwest Italy, as well as France
• Milan – the main hub for northern Italy, the lakes, and international connections to Switzerland and France
• Bologna – a large national rail hub for both high-speed and regional trains
• Florence – centrally located between Rome and Bologna, with easy onward travel throughout Tuscany
• Rome – a key hub for Lazio and onward connections to Italy’s Adriatic coastal cities such as Pescara and Bari
• Naples – gateway to Pompeii, Sorrento and Campania via regional lines
• Salerno – the southern end of the high-speed network, with onward connections to southern Italy (Reggio Calabria) and Sicily via Messina

Ticket classes on a general level are similar to airlines:

• Economy/Super Economy – comfortable seating with basic refreshments
• Business Class – larger seats, more space, enhanced food and drink, and greater flexibility
• Prima (First Class) – the highest class with maximum comfort, often including pre-departure lounge access at major train stations such as Roma Termini and Napoli Centrale

High speed trains always feature reserved seating only, air conditioning, power sockets, luggage racks, and seated carriages. You’ll often find also a bar/cafè service onboard (beyond the complimentary refreshments) in a restaurant car or simple café service.

When booking, you can usually choose your seat (sometimes for an extra fee subject to the route and demand), add cancellation insurance, or pay extra for lounge access at major stations if this isn’t included by default in your ticket. These lounges offer WiFi, comfortable seating and complimentary refreshments prior to your journey, and are a great way to avoid what are often very busy main station areas.

Intercity trains run on main routes between major cities and coastal destinations, covering areas where high speed services do not operate. They are slower than high speed trains but more comfortable than regional services, normally with reserved seating and onboard facilities.

Night trains operate on selected long-distance routes (such as from Sicily to Rome) and remain a useful option for overnight travel. Night trains operate with sleeping compartments, couchettes and seated carriages, allowing you to save time and accommodation costs.

There are several ways to book train tickets in Italy but generally only one approach that I now follow – let me outline all the options for you here so you have a complete picture, plus my recommended way to buy train tickets:

1. If you are already in Italy, you can buy tickets at stations using ticket desks or automated machines. However, this isn’t always convenient, especially if you’re travelling during busy periods.
2. You can also book directly with the official train operators. This usually gives you the best base fare, but it requires knowing which operator runs the route you want.
3. My preferred option is using a platform like Trainline. It shows all available trains on a route across operators and highlights the best time and price options. I’ve used it for years, both in the UK and Italy, because the app and website are simple to use. Digital tickets also mean no paper validation is required on most services, saving even more time compared to traditional methods.

Between regional trains and city metro systems sit local rail services such as Rome’s Metromare and Campania’s Circumvesuviana. These can be confusing, as some are integrated into city transport networks while others require separate tickets. Always check ticket validity carefully.

Rome, Milan and Naples each operate metro systems that function like underground railways. While smaller than those in cities like London or Paris, they are fast, affordable and practical.

Milano is home to Italy’s largest metro network which enables visitors and locals to get around this huge city efficiently. Unlike Rome and Naples, there is no one single main connection point, where the four lines criss-cross the city, similar to the New York subway system.

Naples has a multi-line metro network integrated with buses and trams. Some stations are famous for their design, often referred to as “art stations.” Dante station is our personal favourite where the walls are lined with the texts of the famous Italian writer. Parts of the Circumvesuviana line are included in the network, while others, such as the Campania Express, are not. For more information on Naples’ transit network, visit Napleswise here.

Other cities from north to south in Italy feature smaller metro and fast-transit networks, including Genoa in Liguria, Turin in Piemonte, Brescia in Lombardy and Catania in Sicily.

Rome’s metro includes Lines A, B and C, along with additional rail services integrated into the same ticketing system. Buses and trams are part of the same network. Note that the train to Fiumicino Airport is not included and requires a separate ticket reservation.

Italy train travel is reliable, efficient and accessible for first-time visitors and experienced travellers alike. With many trains running daily, a well-connected high speed network, and clear ticketing options, trains remain one of the best ways to explore Italy.

Whether you’re travelling between major cities, following popular routes, or planning slower journeys using regional services, understanding the basics of Italian trains will help you travel with confidence – and make the journey part of the experience, not just the logistics.
