The SEA HSL project is the extension of the Atlantic HSL, starting from Tours to Bordeaux. The project objective is to significantly improve rail services of the south-eastern part of France, allowing commuters to go from Paris to Bordeaux in around 2 hours (3 hours before the HSL). The SEA HSL is a Public-Private Partnership (PPP) contract involving one consortium divided in 3 entities: LISEA, a consortium formed by Vinci, Ardian and Meridiam, COSEA (formed by Vinci Construction France TP Lyon, Botte Fondations and EMCC), which was in charge to design and construct the HSL and MESEA (formed by Vinci Concessions and Systra) which is currently responsible for the maintenance, and operation of the SEA HSL. SNCF Réseau was in charge to part-fund, design and construct the connections of the SEA HSL to the French network. The SEA HSL Project consists of a main section of 302-km double track line between Tours and Bordeaux, with 7 connections to the French network totalling 38km of additional double tracks. The main section is 25kV – 50Hz electrified and is equipped with GSM-R, ETCS L2 and TVM 300 (French Class B System). Rolling stock running on the SEA HSL are equipped with ETCS L2 and/or with French national signalling system (TVM 300 / TVM430). The SEA HSL line totals 449 structures (222 road bridges, 142 rail bridges, 40 viaducts, etc.) The line has been commissioned in 2017.
