The LGV Rhône-Alpes (short for Ligne à grande vitesse Rhône-Alpes , "high-speed route Rhone-Alps") is a high-speed route in France . It is 115 kilometers long, is used by TGV trains and is named after the Rhône-Alpes region in which it is located. The route bypasses the greater Lyon area and leads to the vicinity of Valence . It is also the first French high-speed line designed for speeds of 320 km / h.
route
Four departments are crossed; from north to south these are Ain , Rhône , Isère and Drôme . The route begins at Montanay , where it branches off from the LGV Sud-Est . It initially runs in a south-easterly direction, crosses the Rhone and turns south. The first section ends at Saint-Quentin-Fallavier , where there is an extension to the old Lyon - Grenoble line , which is also used by trains going to Italy .
The second section has two longer tunnels , the Tunnel de Meyssiez (1780 m) and the Tunnel de la Galaure (2680 m). A few kilometers after crossing the Isère , the route ends at Saint-Marcel-lès-Valence . On the one hand it merges with the LGV Méditerranée towards the south, on the other hand there is a threading out onto the old line to Valence .
features
The first section in the north (42 km) between Montanay and the Saint-Quentin-Fallavier junction, opened in 1992, is designed for a speed of 300 km / h. The minimum curve radius is 4000 m, the track center distance 4.2 m.
The southern second section (73 km), opened in 1994, between the Saint-Quentin-Fallavier junction and the Valence TGV station can be driven at 320 km / h, the maximum gradient is 35 ‰.
The engineering structures include ten viaducts with a total length of 4.5 km and four tunnels with a total length of 5.3 km. The completely double-tracked line is electrified with 25 kV 50 Hz alternating current . The entire route is monitored and controlled from a control room in Lyon-Perrache train station .
