Milan - Limbiate suburban tramway, Italy
Reconstruction of the Milan–Limbiate Extra-Urban Tramway, Italy
On the northern outskirts of Milan, MM SpA (Metropolitana Milanese) has awarded to the consortium led by GCF – Generale Costruzioni Ferroviarie the redevelopment project of the Comasina “Frecciarancio” tram line.
The project provides for the complete demolition of the existing single-track line running alongside the road. In some sections, the current alignment will retain its function as a tramway right-of-way, while in other sections, where possible, the route will be completely reconfigured to allow the track to be laid on a dedicated, reserved right-of-way in the center of the roadway between the two carriageways.
A total of 19 stops are planned along the 11.70 km route, which, for financial reasons, is divided into two sections: Lot 1, from Milan Comasina to the Varedo depot (7.92 km, with 13 stops); Lot 2, from the Varedo depot to Limbiate – Monte Grappa (3.78 km, with 6 stops).
To achieve the required performance targets—adequate commercial speed, regular, reliable and safe service, and satisfactory tram frequency—the project includes, where possible, double tracking over a total length of 3.54 km.
Features of the new line
The line will be equipped with entirely new technological systems, including: track laid on a grass-covered surface with an irrigation system; the electric traction system, comprising electrical substations, feeders and overhead contact lines; electrical and special systems (switch control boxes, remote switch control system, audio-video system, remote operation system, SDH transmission system, telecommunications cables); finishing works at stops (shelters, barriers and other stop furnishings); and the installation of systems at the stops.
A complete reconstruction is also planned for the existing roadways—and their related underground utilities (sewers, pipelines and cables)—which will be progressively renewed and adapted to the new metro-tramway configuration. This includes the construction of curbs, pedestrian and cycle path pavements, and stop platforms which, with a height of 0.22 m above rail level, together with future low-floor trams, will ensure virtually level boarding. All stops will also be equipped with tactile paths for visually impaired users.
Among the major civil works are the new depot and maintenance facility in Mombello and the “philological” widening of the historically and culturally significant Villoresi Bridge.
