The LGV Sud-Est (French: Ligne à Grande Vitesse Sud-Est; English: South East high-speed line) is a French high-speed rail line which connects the Paris and Lyon areas. It was France's first high-speed rail line. The inauguration of the first section between Saint-Florentin and Sathonay-Camp by President François Mitterrand on 22 September 1981 marked the beginning of the re-invigoration of French passenger rail service.
Other LGV projects have extended the reach of high-speed trains that use this line, including the LGV Rhône-Alpes and LGV Méditerranée to the south and the LGV Interconnexion Est to the north. These connecting lines shortened journey times between Paris and the southeast of France (Marseille, Montpellier and Nice), Switzerland and Italy, as well as between the southeast and the north and west of France, the United Kingdom and Belgium. The LGV Rhône-Alpes, Sud-Est and Méditerranée, taken as a whole, were also nicknamed the City To Coast (C2C) Highway ("Ville à la Mer").
Route
The line crosses six departments, from north to south:
The TGV system is compatible with the regular rail network, avoiding the need for new infrastructure construction to reach existing train stations in the dense urban areas of Paris and Lyon.
The distance from Paris (Gare de Lyon) to Lyon (Part-Dieu) is 425 km (264 mi). The LGV route is 409 km (254 mi) long; by avoiding built-up areas between Paris and Lyon (particularly Dijon) this enables a route 87 km (54 mi) shorter than the regular line, which is 512 km (318 mi) long. There are no tunnels.
The line includes various connectors to the regular rail network:
- at Pasilly-Aisy towards Dijon, and further through the Jura Mountains to Vallorbe and Lausanne or Neuchâtel and Zurich
- at Mâcon-Pont-de-Veyle towards Bourg-en-Bresse and the Savoie department
- at Saint-Florentin
- at Le Creusot station
- at Mâcon-Loché station
These last three are used by service trains or in order to divert passenger trains if needed.
The line runs next to the A5 autoroute for 60 km (37 mi) and the N79 road for 15 km (9.3 mi). For its full length, a 5 m (16 ft)-wide area has been reserved for a telecommunication artery.[citation needed]
Line specifics
The line has a surface area of 16 km2 (6.2 sq mi) – in comparison Charles de Gaulle Airport occupies 32 km2 (12 sq mi) – with an average width of 40 m (130 ft).[citation needed] Platforms are 13 m (43 ft) wide, with a space between track centres of 4.2 m (14 ft). The line was designed for a nominal speed of 300 km/h (190 mph), with a minimum radius curve of 4,000 m (13,100 ft) – although seven curves were made to a smaller radius, but no less than 3,200 m or 10,500 ft.[citation needed]
In total, the line comprises 847 km (526 mi) of track. This is formed by UIC 60 (60.3 kg/m [40.5 lb/ft]) rails placed in 288 m (945 ft) lengths, welded in place (with certain segmented sections). The 2.41 m (7 ft 11 in) concrete sleepers are formed of two blocks of concrete tied together by a metal strut. There are 1660 sleepers per kilometre.
Traction power is supplied by eight EDF substations at 25 kV AC, 50 Hz. The catenary is fed by an inverted phase "feeder" cable, which is equivalent to a 50 kV supply and reinforces the available power, enabling a single trainset to draw up to 14 MW.[citation needed]
Signalling relies on high-frequency track circuits, signals being transmitted directly to the driver's console. There are lineside marker boards indicating the limits of each block section, but no signals as such.[citation needed]
The highest point on the line is 489 m (1,604 ft) above sea level, near the town of Liernais, 55.5 km (34.5 mi) north of Gare du Creusot. This is near the range dividing the Seine and Loire river valleys, and not far from the Rhône river valley.[citation needed]
Stations
The LGV Sud-Est serves the following stations:
Le-Creusot and Mâcon-Loché are basic stations situated away from built-up areas. They have four tracks, with the two central tracks being reserved for through trains, and the side tracks serving stopping trains on two side platforms.
Costs
Item | Cost, nominal[2] (in 1984 francs) | Cost, real (in 2007 euros) |
---|---|---|
Construction of superstructure and infrastructure | 7.85 billion | 2.0 billion |
Construction of superstructure and infrastructure, with land purchase | 8.5 billion | 2.15 billion |
Rolling stock | 5.3 billion | 1.35 billion |
Total | 13.8 billion | 3.5 billion |
From 1996, the track of the LGV Sud-Est was renewed at a cost of FRF 2 billion,[2] or about €300 million.
