The team has been commissioned by Italferr to design and build the Naples - Cancello section of the route.
The project, which is scheduled for completion by 2022, is the first section of the Naples - Bari line, a key part of plans to upgrade of the railway lines throughout the country.
The section between Naples and Cancello will bring rail service to the new Napoli Afragola station, which will act as the point of transfer between regional and high-speed services, improving access to rail services in Naples. The project also includes the construction of the Acerra station and two urban stations. The section will extend for about 15.5km across the Casoria, Casalnuovo, Afragola, Caivano and Acerra areas.
The Naples - Bari route is part of the Scandinavia - Mediterranean Corridor of the Trans-European Network (TEN).
Salini Impregilo has a 60% share in the consortium, with Astaldi holding the remaining 40%.
