The machines will excavate Lot 1A Battipaglia–Romagnano of the new railway line in Italy.
According to Greek mythology, Leucosia and Ligea were sirens that dwelled along the shores of the Bay of Salerno.
Leucosia means the white one or the radiant one, while Ligea means clear-voiced or melodious.
One of the two 13.46m-diameter TBMs will excavate the more than 800m-long Serra Lunga tunnel and will then continue with the 250m-long Acerra tunnel and the Petrolla tunnel, which will be more than 1.2km. The other will dig the Piano Grasso tunnel, more than 2.2km long, followed by the Contursi tunnel, which will be over 1.5km.
They will join TBM Partenope – launched in February this year – which is excavating the Saginara tunnel.
Xenia Consortium, led by Webuild with partners Pizzarotti, Ghella, and Tunnel Pro, is responsible for Lot 1A.
