In 2026, both Italo and Trenitalia (Frecciarossa) are considered highly reliable for high-speed travel between Italy's major cities, with punctuality rates that often exceed 90%. Italo, being a private company, exclusively operates high-speed trains on the main "backbone" routes (Naples to Milan/Venice), which allows them to maintain a very modern fleet and high maintenance standards. Trenitalia, the state-owned operator, runs the Frecciarossa high-speed service which is equally fast and reliable, but it also manages the entire regional and intercity network. Generally, if there is a rail strike—which is a known factor in Italian travel—Italo sometimes manages to run a "guaranteed" schedule of its limited high-speed services, whereas Trenitalia's massive network can be more broadly affected. For a tourist traveling between Rome, Florence, and Milan, the reliability is virtually identical; the choice usually comes down to which operator offers the better price or a more convenient departure time for your specific itinerary.
