London to Rome by train

There are no direct trains from London to Rome. The journey requires at least two changes and takes around 14 hours on the fastest same-day connections. Most travellers find it easier to break the trip with an overnight stop in Paris, Lyon, Turin, or Milan, arriving in Rome fresh the next morning.

The standard route starts with a Eurostar from London St Pancras International to Paris, then a high-speed train through the Alps to Turin or Milan, followed by an Italian high-speed train to Roma Termini. Eurostar fares start from around £39 in Standard class. The Paris to Turin or Milan leg can start from around €29 in advance for second class. Italian high-speed trains from Milan or Turin to Rome start from around €19 to €29 in standard class. Booking each leg early matters. Advance fares sell quickly on all three segments, and prices rise sharply as the departure date approaches.

Route options

Via Paris

This is the standard route. Use it unless you have a specific reason not to.

Take a morning Eurostar from London St Pancras International to Paris Gare du Nord. From there, take the RER D to Paris Gare de Lyon, two stops. Allow 60 to 90 minutes for this transfer; it takes longer than the map suggests. From Gare de Lyon, take a high-speed train to Turin Porta Susa or Milan Centrale, then an Italian high-speed service to Rome.

Two trains serve the Paris to Milan corridor. Trenitalia’s Frecciarossa is the newer of the two and arrives at Milan Centrale, which has far more onward connections. The SNCF TGV covers the same corridor but arrives at Porta Garibaldi, a smaller station on the edge of the centre. Both take around six to seven hours from Paris. Advance fares are broadly similar. If you are continuing to Rome the same day, the Frecciarossa is the easier choice, Centrale has frequent Frecciarossa and Italo departures for Rome throughout the afternoon.

Milan to Roma Termini takes roughly three hours.

Via Lille

Take a Eurostar to Lille Europe, the train stops there before Paris, so no separate booking is needed. From Lille, change at the same station onto a service to Lyon Part-Dieu. Stay overnight in Lyon, then take a morning Frecciarossa to Turin and Milan.

This route adds a day, but it cuts out the Paris station change entirely. Worth considering if you have heavy luggage or simply don’t want to rush across Paris on a tight connection.

Current service note

Direct Paris to Milan trains, Trenitalia’s Frecciarossa and the SNCF TGV, are running normally. Scheduled maintenance in the Mont Cenis tunnel will pause them from 11 September to 9 October 2026. If you are travelling in that window, check alternative connections before you book.

Overnight and sleeper options

No direct sleeper runs from London to Rome.

The most practical option is a planned hotel stop in Paris, Lyon, Turin, or Milan, then an early train to Rome the next morning. Most travellers who attempt the whole journey in a day find it exhausting by the time they reach Roma Termini.

From September 2026, the European Sleeper service runs overnight from London via Brussels to Como and Milan, on Mondays, Thursdays, and Saturdays. You arrive in Milan the next morning and take an Italian high-speed train onward to Rome. It is a new service, so check availability early.

There is also a Nightjet sleeper from Stuttgart to Venice. Combined with a Eurostar and TGV from London to Stuttgart, this gets you to Venice overnight. From Venice, you continue to Rome by day train. It is a longer route with an extra change, but it works well if Venice is also on the itinerary.

Tickets and fares

Each leg is a separate ticket bought from a different operator.

London to Paris, Eurostar Standard fares start from around £39 for advance bookings. Plus class includes a meal at your seat on London routes. Premier is the top tier, with lounge access and a sit-down dining service. Prices move considerably by date and demand.

Paris to Turin or Milan, Frecciarossa or TGV Second-class advance fares on the Frecciarossa start from around €29. The TGV is similar on the same corridor. Check both when you search, prices and times differ by date, and the gap can be worth looking at.

Turin or Milan to Rome, Trenitalia or Italo Advance standard-class fares start from around €19 on Italo and around €29 on Trenitalia’s Frecciarossa. Both run frequent services and take roughly the same time. Italo tends to be cheaper for flexible advance fares.

Seat reservations Seat reservations are included in the ticket price on Frecciarossa and Italo. There is no separate reservation fee if you are buying a full ticket. Pass holders work differently, see below.

Combined cost Booking all three legs well in advance, standard class across the whole journey can start from around £100 to €150. Last-minute booking or upgrading one leg to business class changes that substantially.

Service types by leg

Where to book

Book Eurostar directly at eurostar.com. For the Frecciarossa, go to trenitalia.com; for Italo, italotreno.it. Direct booking on the Italian legs is usually cheaper than going through an aggregator. Rail Europe and Trainline let you search across operators, which is useful for comparing options, but they add a service fee at checkout.

When to book

Eurostar opens around six months ahead. Trenitalia opens around four months out, Italo around three to four months. The cheapest fares are limited and go first on popular summer and weekend departures. Book as soon as dates are fixed. Prices on the same route can vary noticeably between Monday and Friday of the same week, so check a few days if you have flexibility.

Interrail and Eurail passes

An Interrail or Eurail pass covers the continental legs of this journey from Paris or Lille onwards. Neither pass includes Eurostar or UK domestic trains. You need a separate Eurostar ticket regardless of which pass you hold.

UK residents are European residents, so the correct pass is the Interrail Pass. Eurail is for travellers from outside Europe.

Pass holders still need to pay a seat reservation fee on Italian high-speed trains. This is separate from the pass, not waived by it. Book these reservations at the same time as your journey, especially for summer departures. Pass-holder places on popular trains fill up before the general ticket pool runs out.

Connections and transfers

Transfer cities

Paris

The transfer between Gare du Nord and Gare de Lyon is where this journey can unravel. The RER D connects them in two stops, but getting from the Eurostar platform to the correct RER entrance, then navigating Gare de Lyon and finding your train, takes time. Allow 60 to 90 minutes. If the Eurostar runs late, you may miss the Paris to Milan connection. Build in some buffer when you book.

Train facilities

Eurostar Plus and Premier passengers get meals. Standard passengers buy from the cafe-bar. The Frecciarossa and TGV both have cafe-bars open to all. You can bring your own food on all three trains.

When to travel

April, May, September, and October are generally the better months. Temperatures in Rome are manageable, crowds are smaller, and train availability is easier than in high summer.

July and August are the busiest period. Eurostar and Frecciarossa departures on summer Fridays and Sundays can sell out weeks ahead. If you are going in summer, book well in advance.

Arriving in Rome

Roma Termini

High-speed trains from Milan and Turin arrive at Roma Termini. It is Italy’s largest station, with 31 platforms connected by a central concourse. Scan the QR code on your ticket to enter the platform area. The departure board shows the platform number (binario) around 15 to 20 minutes before each service.

Metro lines A and B both serve Termini, and there is a bus terminal at the main entrance.

Getting into the city

A single ATAC ticket costs €1.50 and is valid for 100 minutes across the metro, bus, and tram. Day passes (24-hour, 48-hour, 72-hour) are worth buying if you plan to use public transport regularly. Bus 40 Express runs past the Vatican, Spanish Steps, Pantheon, and Colosseum. Validate your ticket before boarding any bus or tram.

Taxis from Termini to central Rome typically cost €10 to €25 depending on where you are headed. There is a fixed fare for Fiumicino Airport, but city journeys run on the meter.
