The project for upgrading the Empoli-Siena line includes the electrification of the entire section and a doubling of the track between Empoli and Granaiolo by about 10 kilometres alongside the current track.

With reference to the section being doubled, the elimination of all level crossings along the line and the activation of new equipment for handing train circulation are also planned. The complex of interventions shall lead to an increase in metropolitan services and the speeding up of the Florence-Siena rapport.

Vincenzo Macello was appointed Extraordinary Governmental Commissioner for completion of the works.
