Travel from Naples to Rome

Train, definitely. Either Trenitalia or Italo would be fine, just pick the one with the preferred price and time. Booking ahead usually gets you some nice price reductions although you must commit to a specific train as economy-priced tickets aren't refundable or changeable. Seats on both for the Napoli Centrale> Roma Termini (assuming that's your station of arrival) will be reserved. 2nd class/Standard (or "Smart" in the case of Italo) is fine: no need to pay for a more expensive carriage as the trip will only take a bit over an hour.

Yes, you can certainly take the train from Naples to Rome.

There are multiple train traveling this route; Freccia (high-speed) trains, and Regionale trains. The Freccia trains take about an hour & 15 minutes to travel this route and they’re more expensive. The Regional trains are less expensive but they’re slower.

You can check train schedules here: Trenitalia.com

If you’d like to save money, you may book your discounted (Promo) Freccia train tickets up to 120 days in advance.

You’ll need to choose the following stations:

• Naples = Napoli Centrale
• Rome = Roma Termini

Have a wonderful trip!

Pay attention that the advance purchase discount is like airline tickets: Your train trip is for only one departure, and is not refundable or changeable. We got to the Naples station well before the preceding Frecciarossa left for Rome, but they would only consider a full-fare, walkup price. So we sat on our luggage for an hour and used our discount ticket printouts.

We’d arrived at the train station in Naples via a separate train from Sorrento to Naples. We walked over to the ticket area to get tickets for the next train to Rome, as long as the price worked. As I recall, Italo was more euros at the time, and we’d have to wait longer for their train, so went with Trenitalia.

Approaching Rome, we got off at the stop that was a 2 or 3 minute walk from the Ostia Antica ancient Roman town and ruins, just west of Rome. They let us stash our luggage for free in the entrance guards’ shack, and tour the fascinating ruins and surviving mosaics and buildings on foot. It’s kind of like seeing Pompeii, except it wasn’t destroyed by a volcano. When we were done seeing Ostia Antica, we took a taxi to our hotel. Basically door to door service, first by train, then by taxi.
