While the cities are already linked by rail, the fast train via the airport will save inbound travellers having to head to either Termini or Tiburtina station on the other side of Italy’s capital.
CEO of the Italian state railway company, Gianfranco Battisti, announced the new initiative on Tuesday, saying the aim is to create “a great integrated transport network” connecting Italy’s “stations, airports and ports”.
Battisti added that a similar service would be introduced at Milan’s Malpensa airport next year.
“We are highly confident that Malpensa can become another transport opportunity that we will develop with the Frecce [trains] in 2019,” he said.
The railway company will also increase the number of high-speed trains between Milan and Rome from December, according to Italian media.
Services will also be extended between Milan and Venice, and between Florence, Rome and Naples, while there will be extra trains on weekends between Rome and Bari.
