started on the first dual-voltage sets in 2004 at SNCF's Hellemmes workshops, near Lille. In 2006 the last dual-voltage set was finished. Between 2008 and 2009 the three-voltage sets will also be refurbished in the same design. The refurbished sets can be distinguished from the non-refurbished ones by: the slightly changed livery; the fittings in the coaches, which are in new colours (red for 2nd class, yellow-green for 1st class and silver for the bar) and the reflecting stripes on the sides of the motorcars. Although SNCF announced in July 2007 that the Lacroix-design would not be continued because some materials vibrated at , this was later changed: the Lacroix-design will be applied to all TGV Réseau sets.
