The fleet of 40 dual-voltage (25kV 50Hz ac/1.5kV dc) double-deck trains - dubbed TGV Océane by SNCF - were ordered in March 2012 using a €1.2bn option from a contract awarded to Alstom in 2007.

Seventeen TGV Océane will be in service by the time the 302km Tours - Bordeaux high-speed line opens on July 2 2017 and the remainder of the fleet is due to be delivered by the end of 2019.

The TGV Océane features a new exterior livery, which reflects towns and cities in the regions of Occitanie and Nouvelle Aquitaine.
