The LGV Sud Europe Atlantique (short: LGV SEA ) is a high-speed route in France . It was opened on July 2, 2017 and connects the cities of Tours and Bordeaux as a southern extension of the LGV Atlantique . It is 302 kilometers long, plus 38 kilometers of connecting lines to the Poitiers and Angoulême stations . The route runs largely parallel to the old, now overloaded railway line. The LGV Sud Europe Atlantique is designed for a top speed of 320 kilometers per hour.

When it went into operation, the distance between Paris and Bordeaux was shortened to 537.14 km. The fastest TGV need two hours and three minutes for this, and the cruising speed is then 262.0 km / h.

financing

The line was built by the construction company Vinci in an operator model . The company prevailed against the competitors Bouygues and Eiffage . Bank Caisse des Dépôts and the insurance group Axa are among others involved in the consortium .

Half of the planned construction cost of 7.2 billion euros will be given by the central government and local authorities as a subsidy, the rest will be provided by Vinci. This is offset by a fixed budget of 7.8 billion euros, including expected price increases. The group is allowed to charge user fees for this for 35 years. Vinci is to receive a loan of three billion euros from the European Investment Bank . The new line could increase passenger traffic between Paris and Bordeaux by three million to 19 to 20 million travelers per year.

history

Preparations

On September 25, 1990, the southwest branch of the LGV Atlantique, leading to Saint-Pierre-des-Corps near Tours, was put into operation. Since then, TGV trains have been running between Paris and Bordeaux. The overall plan for the French high-speed lines presented on April 1, 1992 then contained the project of a line called LGV Aquitaine as an extension of the LGV Atlantique to Bordeaux. The first feasibility studies were carried out between 1997 and 1998. Before implementation, the route was then divided into two sections: Tours-Angoulême and Angoulême-Bordeaux.

Tours-Angoulême

Studies on this section of the route were only carried out between 2004 and 2006. On April 16, 2007, the project was officially approved by the Ministry of Transport. The primary public interest in this was declared in spring 2009.

Angoulême-Bordeaux

Following official studies from 2001 to 2003, the regional planning procedure was initiated in 2005 . On July 20, 2006, priority public interest in the project was officially established. In preparation for the construction of the high-speed line, a second parallel railway bridge was built over the Garonne in Bordeaux by 2008 . By September 2010, the second pair of tracks was connected to the Bordeaux-Saint-Jean station .

construction

In the years 2010 to 2011, preparatory work was carried out, such as the clearing of forests or archaeological excavations on the later route. The actual civil engineering work and the construction of the engineering structures began at the end of 2011 and lasted until the beginning of 2015. During 2015, the line was equipped with the railway infrastructure. The first test drives then took place from mid-2016.

Infrastructure

The LGV SEA near Raix ( Charente department ).

Like every new line in France, the line is electrified with 25 kV 50 Hz AC voltage . The signaling consists of TVM 430 and ETCS Level 2 ; it will be supplied by Ansaldo STS . A total of 60 million euros were invested, of which 47 million were allocated to the TVM 430 and 13 million to ETCS Level 2.

The route is connected to the existing network at eight points with a total length of 38 km. Stations outside of cities, such as on former French high-speed lines, are no longer provided.

vehicles

A further 40 TGV Duplexes were ordered from Alstom as rolling stock, all of which should be delivered by the end of 2019. They are to gradually replace the previous TGV Atlantique . The price per unit is 30 million euros.

Planned continuations

Two further high-speed lines are to be built from Bordeaux by 2020: the LGV Bordeaux – Espagne to the Spanish border to Irun and the LGV Bordeaux – Toulouse . The travel time from Paris to Toulouse will then be just over three hours compared to five hours today.
