Rome-Florence Direttissima High Speed Railway

It is 254 km long, 60 km shorter than the previous line, which continued to be used.

Thanks to its technical characteristics, considerably greater speeds were possible on the express line, allowing for shorter travel times.

The "Direttissima" was the first high-speed railway line in Europe, with more than half of its total length opening on Feb. 24, 1977. Allowing for speeds of up to 250 km/h, the Rome-Florence line represented, in those years, the frontier of modern rail transport.

Lot 1: For a total length of 35,450 m, works involved the construction of 9 tunnels, 14 viaducts, 2 bridges across the Tiber River, for a total volume of 900,000 m3 of excavations and 1,300,000 m3 of earth removal.

Lot 2: The line runs from Stimigliano to Orte for a total length of 21,350 m, of which the first 11 km are in the open air while the remainder is in tunnels. The external work ran along the Tiber valley and the main works consisted of 5 viaducts for a total length of 2,500 m.

Lot 5: The section runs from the Orte station to Orvieto station for a total length of 41,350 m, including 104 bridges and viaducts, of different dimensions.

Lot 7. The line runs for 23,385 m in Val di Chiana section, comprising 5 tunnels for a total length of 3,100 m with an average design section of 100 m2. Works required 400,000 m3 of excavations, 1,600,000 m3 of removed earth, 390,000 m3 of concrete and 47,000 m of tracks.
