The route, explained
Start with the same France–Italy corridor as the Naples journey, then choose Rome as your final stop. The itinerary is built around a night in Lyon, leaving room to compare the onward departure from Milan.
Roma Termini is the central terminus, while Roma Tiburtina also serves high-speed trains. Check the station in the result against where you are staying. A train calling at Rome is not necessarily a train calling at Termini.
On a multi-day trip, review the Milan connection together with your arrival in Rome. An earlier final arrival may be more useful than a shorter total trip with a late finish. Use the planner to compare both, then book with the operators.
This route avoids changing stations in Paris. Lille is the connection into France, and Lyon is the planned overnight stop before the Frecciarossa corridor to Turin and Milan.
Yes, Naples is a separate onward destination on Italy's high-speed network. See the London–Naples guide if you want the whole trip to finish there, or add Naples in the planner after a stay in Rome.
