Last October the GTF 250 RC completed an important project inside the Valico tunnel on the A15, the Autostrada della Cisa, in the northbound tunnel tube near the Berceto exit.
After completing a series of tests, the GTF 600 RC arrived at the site located next to the Genova Brignole train station where it is being used to excavate a 110 m tunnel linking the two main tubes.
The video illustrates the main stages of development that led to the new GTF 600.
