These TGV trainsets are based on the earlier TGV Atlantique. The first Réseau ("Network") sets entered service in 1993. Fifty dual-voltage trainsets were built in 1992-1994, numbered 501-550. A further 40 triple-voltage trainsets, numbered 4501-4540, were built in 1994-1996. The last ten triple voltage units carry the Thalys livery and are known as Thalys PBA (Paris-Brussels-Amsterdam) sets. As well as using standard French voltages of 25 kV AC and 1,500 V DC (also used in the Netherlands), the triple voltage sets can operate under the Belgian and Italian 3 kV DC supplies. They are formed of two power cars ({{Convert|8,800|kW|sigfig=4|disp=or|abbr=on}} under 25 kV—like the TGV Atlantique) and eight carriages, giving a capacity of 377 seats. They have a top speed of {{Convert|320|km/h|0|abbr=on}}. They are {{Convert|200|m|0|abbr=on}} long and are {{Convert|2.904|m|ftin|abbr=on}} wide. The dual-voltage sets weigh {{Convert|383|t|0|lk=out|abbr=on}}, and owing to axle-load restrictions in Belgium the triple-voltage sets have a series of modifications, such as the replacement of steel with aluminium and hollow axles, to reduce the weight to under {{Convert|17|t|1|abbr=on}} per axle. Owing to early complaints of uncomfortable pressure changes when entering tunnels{{Citation needed|date=November 2016}} at high speed on the LGV Atlantique, the Réseau sets are pressure-sealed. RenovationAfter some ten years of successful service, the interior of TGV Réseau sets became outdated and needed a refurbishment. This refurbishment was part of the TGV Est project, as the dual-voltage sets were to assure the domestic services there. The same interiors would also be used in coaches for POS sets (which were coaches of former TGV-Réseau sets). Three possible interiors were presented to the public between 2002 and 2003 in different stations:
At the end of the Train Capitale exposition in Paris, MBD Design and Christian Lacroix were announced as the winning design. Work 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 {{Convert|300|km/h|0|abbr=on}}, this was later changed: the Lacroix-design will be applied to all TGV Réseau sets.
