TheLGV Rhône-Alpes (French:Ligne à Grande Vitesse; English: high-speed line) is a 115 km (71 mi)Frenchhigh-speed rail line situated in theAuvergne-Rhône-Alpes region which extends theLGV Sud-Est southwards. Opened to service in 1994, the line bypasses the built-upLyon area towards the east; in addition it servesLyon-Saint-Exupéry TGV station (known until June 2000 as Satolas TGV station). BeyondValence TGV station the line is continued by theLGV Méditerranée. LGVs Rhône-Alpes, Sud-Est and Méditerranée, when completed, received their official nickname, theCity To Coast (C2C) Highway ("Ville à la Mer").

The line was constructed in two sections, north and south. The first section was opened in time for the1992 Winter Olympics inAlbertville.

The line crosses four departments from north to south:Ain,Rhône,Isère andDrôme.

The route of the new line represents a total length of 115 km (71 mi); 42 km (26 mi) fromMontanay toSaint-Quentin-Fallavier, and 73 km (45 mi) from Saint-Quentin-Fallavier to Valence. The line is connected to the regular network by links at Saint-Quentin-Fallavier, enabling links toSavoie,Isère andItaly viaChambéry andModane.

The line has a surface area of 12.18 km² (4.70 sq mi) (in comparisonLyon-Saint-Exupéry Airport occupies the same area).

Like theLGV Sud-Est, the line was designed for a nominal speed of 300 km/h (186 mph), with a minimum curve radius of 4,000 m (13,000 ft), and a space betweentrack centres of 4.2 m (14 ft). The second section is designed for 320 km/h (199 mph).

The line includes 10 large viaducts (total length 4.3 km (2.7 mi)), and 4 tunnels (total length 5.3 km (3.3 mi)).

A command post named CCT (Commande centralisée des trains - Central Train Command) enables the continual monitoring of trains running on the entire line and to remotely control security installations. It is situated in Lyon, in an SNCF building near thegare de Perrache.

The line comprises one new station:Gare de Lyon Saint-Exupéry, situated in the commune ofColombier-Saugnieu. This station, with its striking architecture, is the work of the Spanish architectSantiago Calatrava. It serves theLyon–Saint-Exupéry Airport.
