Summary: InOui is neither rolling stock nor an acronym. This new branding inOui, or TGV inOui, is the commercial brand for the French TGV service presented by SNCF on 27 May 2017 initially for certain services, then applied to all ‘classic’ TGVs from 2020. The SNCF was thereby embarking on a branding policy revolving around the onomatopoeic ‘Oui’ (Ouigo, OUI.sncf, Ouibus and therefore InOui), in order to distinguish it from the Ouigo, Lyria, Eurostar or Thalys brands. The inOui brand also puts an end to targeted commercial products such as ID-TGV or TGVMax. The former commercial site VoyagesSNCF.com has become ‘OUI.sncf’. The visual identity is what is known as an ambigram, which can be read both forwards and backwards via a central symmetry of 180 degrees. It applies to the entire SNCF TGV service and to high-speed rolling stock other than the brands mentioned above.

TGV inOui is the premium high‑speed service operated by the SNCF, introduced in 2017 and extended from 2020 to all conventional TGV routes, alongside Lyria and the low‑cost brand Ouigo. Initially mocked yet defended internally, the name replaced the working title TGV Plus and was chosen to embody comfort, innovation and a renewed customer promise. Trials began on the Paris–Bordeaux–Toulouse corridor before a wider rollout to Lille, Marseille and Nice, with the entire network expected to adopt the brand by 2020. By then, the inOui fleet comprised around 280 trainsets.
The service introduced enhanced onboard features: Wi‑Fi replacing TGV Connect, at‑seat catering with online ordering, the digital concierge Anatole, and automatic ticket changes triggered by geolocation, all contributing to higher satisfaction levels on Paris–Lyon.
Passengers benefit from unlimited Internet access via a captive portal and can order from the Bistro TGV inOui, renamed in 2025. Located in coaches 4 or 14, it offers snacks, drinks and hot or cold meals, with discounts for Avantage, Liberté and Grand Voyageur cardholders. Future TGV M sets will feature a two‑level Bistro car.

National rolling stock from SNCF (past and present)
TGV Atlantique trains, introduced in 1989, totalled 105 sets built by 1992. All underwent Lacroix refurbishment between 2005 and 2010. SNCF planned to retire most units from 2015, ultimately scrapping 76. Since 2019, strategy shifted: 28 remaining sets received RITA modernisation in 2021 and will stay in service until 2029 after nearly forty years.
The TGV-Réseau trains were intended for cross-country routes that bypass Paris, such as Lyon-Nantes or Lille-Montpellier. They are derived from the TGV-Atlantique trains and were numbered in the 500 series for 2-current trains and the 4500 series for 3-current trains. The surplus allowed some TGV-Réseau trains to be assigned to Thalys for service in the Benelux countries.
TGV Duplex 201 – 294 2-current Alstom 1995 –
…
The TGV Duplex trains are made of aluminum to maintain a load of 17 tons per axle despite having two levels. With two trainsets, they can carry 1,020 passengers. There are three generations: Duplex, DASYE, and 2N2. The Duplex trains have power cars identical to the TGV PBKA and operate in Germany, Switzerland, and Spain, but not in Belgium.
TGV Duplex-Réseau 601 – 619 2-current Alstom 2006 –
…
This is a result of a modification to the order for the TGV-Est. SNCF removed 38 power cars from certain TGV-Réseau trainsets and integrated them into new Duplex trainsets, creating the 600 series. Meanwhile, 19 old single-deck TGV-Réseau trainsets received new locomotives similar to those of the TGV PBKA for the launching of TGV-Est.
TGV DASYE 701 – 750 3-current Alstom 2008 –
…
Dasye (Duplex ASYnchrone Ertms) is the second generation of Duplex TGVs. 49 trainsets of the 700 series were built. They feature asynchronous motors enabling operation on lines with ETCS Level 2, including LGV-Est, Perpignan-Figueras, BPL, and SEA. Trainsets 724 to 741 have been dedicated to Spain routes since the LGV to Barcelona opened in December 2013.
TGV Euroduplex or TGV 2N2 in France, is the third generation of the TGV Duplex. These are interoperable trainsets, capable of operating in all neighbouring countries, including Spain (on UIC tracks). Moroccan railways are also equipped with this type of trainset. Part of the fleet has been configured for the Ouigo España service (2021).
The TGV M (“M” for modular) is the result of the new high-speed passenger train platform Avelia Horizon from Alstom. It has a broadly similar design to the TGV Duplex sets, with double deck design and 2 power cars more short. The TGV M is expected to enter service with the French train operator SNCF in TGV service in 2025.
