Transcript
The new high speed TURIN - MILAN line
The route • the viaduct Dora: of 1.410 metres is the longest river viaduct on the route. It consists of 39 spans, 35 of which constructed with double girder structurework in reinforced concrete and two in concrete and steel each with a surface area of 75 metres, placed in the river bed; • the viaduct Chivasso-Aosta: with a length of 980 metres comprises 28 spans, each of 35 metres and enables the new high speed line to cross the provincial road for Montanaro and the existing Chivasso-Aosta line; • the viaduct Santhià: of 3.782 metres is the longest on the route. Made up of 152 spans each of the length of approx. 25 metres, enables the line to cross the A4 motorway junction A4 - A5 of Mont Blanc; The new high speed TURIN - MILAN line • the viaduct Ticino: 1.178 metres long, to cross the river of the same name, will be constructed in concrete and steel with 10 spans to avoid restricting the bed section; • the bored/cut-and-cover tunnel passing under the motorway A4 extends for 1.5 km and is the longest of the entire line. It will be built with a structure in reinforced concrete. The 41 municipalities crossed Province of T urin: Settimo Torinese, Volpiano, Brandizzo, Chivasso, Verolengo, Rondissone, Torrazza Piemonte. Province of Vercelli: Saluggia, Cigliano, Livorno Ferraris, Bianzè, Moncrivello, Borgo d’Ale, Alice Castello, Tronzano Vercellese, Santhià, Carisio, Formigliana, Balocco, Villarboit, Greggio. Vercelli - Sesia Viaduct Province of Novara: Recetto, Biandrate, Vicolungo, Casaleggio Novara, S. Pietro Mosezzo, Novara, Galliate, Romentino. Province of Milan: Bernate Ticino, Marcallo con Casone, Mesero, Ossona, S. Stefano Ticino, Arluno, Sedriano, Pregnana Milanese, Cornaredo, Rho, Pero, Milan. The new line runs approx. 125 km and starts in the vicinity of the station of Torino Stura to finish shortly before the station of MilanCertosa. The route runs closely alongside the A4 Turin-Milan motorway through to the municipality of Sedriano. Here it crosses the A4, runs along the north side of the motorway for about 3 km as far as the municipality of Rho. The line then deviates sharply north-east away from the motorway and after a wide curve to the south-east, re-joins the existing Turin-Milan rail line to enter the junction of Milan. The mainly flat landscape crossed by the lines leads to much interference with existing roadways, with the consequent demolition Vercelli - Interconnection of Vercelli and reconstruction of virtually all current overpasses and branches of the motorway. Most of the line extends along embankments. The geographical characteristics of the area of land concerned do not represent a problem to introduction of the new line. In fact the route exploits the natural lie of the land and runs alongside the motorway to minimise environmental impact without causing other interference on the land. The choice to insert the line within a corridor with an already dense infrastructure has led to the need to deal with a number of interferences of the new line with the rail and motorway network, as well as the water network. The works will contribute to the upgrading and improvement of the infrastructure in an area of the country subject to intense productive traffic. The interventions envisaged regard: the road network (motorway junctions, overpasses, toll gates, service stations), with water network (implementation of hydraulic underground routes, optimisation of connected network) and the upgrading of the corridor (environmental mitigation, extension of viaducts in the areas crossing rivers, to guarantee maximum transfer in the event of high waters, construction of roads for civil protection services etc.). The structural integration with the existing rail line will be by means of five interconnections: two terminals at Settimo Torinese and Milano Certosa and three intermediate ones at Santhià (Vercellese ovest), Novara ovest and Novara est. The interconnections will also serve to route passenger trains on the historical line and freight trains on other itineraries.

The main works include: METROTIPO SpA Technical characteristics RFI COMMUNICATIONS DEPARTMENT Piazza della Croce Rossa, 1 • 00161 Rome • the interconnection of Settimo/Stura where six tracks meet: two for the new high speed line, two for the existing line and two for the new rail line; • the cut-and-cover tunnel of Rondissone: of 1,435 metres is the longest tunnel of this type on the route. The work has great value in terms of the landscape as it avoids any interruption to the continuity of the territory crossed in the vicinity of the Dora Baltea; Vercelli - Interconnection of Santhià Estratto dalle Carte n. 561-562/I° ed. 2003 Map Terms Line in cutting or embankment Line in tunnel Line in viaduct TURIN MILAN Urban crossing on existing line Stations Km 0 Km 10 Km 20 Km 30 Km 40 Km 50 Km 60 Km 70 Km 80 Km 90 Km 100 Km 110 Km 120 Km 125 Estratto dalle Carte n. 561-562/I° ed. 2003 Map Terms Line in cutting or embankment Line in tunnel Line in viaduct TURIN MILAN Urban crossing on existing line Stations Km 0 Km 10 Km 20 Km 30 Km 40 Km 50 Km 60 Km 70 Km 80 Km 90 Km 100 Km 110 Km 120 Km 125
