iDTGV
A former SNCF low-cost high-speed train service offering online-booked TGV journeys in France.
Last updated August 22, 2026
Overview
iDTGV was a low-cost passenger rail service operated as a wholly owned subsidiary of SNCF, France's state-owned railway group. It used TGV high-speed trains on several French high-speed lines and was designed to offer a more price-sensitive and digitally oriented alternative to conventional TGV travel. The service operated principally on routes beginning or ending in Paris and connected the capital with destinations in southern and other parts of France. The referenced description states that the service served 12 French stations. A central feature of iDTGV was its online-only sales model. Customers could purchase tickets through the service's website, generally up to six months before departure. Promotional fares began at €19 per passenger on all routes according to the referenced service description, although exact prices depended on availability and booking conditions. Additional services could also be bought online, often at a lower price than purchasing them onboard. This model placed iDTGV among the early European rail offers built around advance online distribution, differentiated service options and variable pricing rather than a single standardized onboard experience. The onboard proposition was divided into two distinct carriage atmospheres. The iDzen area was intended for passengers seeking a calm environment, including business travelers; mobile-phone use and loud conversation were restricted. The iDzap area targeted families, leisure travelers and passengers who preferred a livelier journey, with more permissive noise rules and food service available at intervals. The separation of these environments was a defining part of the brand rather than merely a seating classification. First-class passengers received wider seats, additional legroom and access to a power socket. The service also offered several ancillary features. A buffet car was available on designated trains, with its location varying by train configuration. In partnership with Navendis, iDTGV operated a pre-booked taxi service called iDcab for journeys in the Île-de-France region. Passengers could rent tablets loaded with films and games, together with headphones, for use during the trip. Seat selection was available during or after booking, although changes to added services required the ticket to be reprinted. Compared with standard TGV services, iDTGV applied stricter baggage conditions. The referenced description specifies an allowance of one item of hand luggage and one suitcase per passenger, with a supplement for additional bags. These rules formed part of the service's low-cost operating model and helped distinguish it from the more flexible conditions associated with conventional TGV travel. iDTGV was ultimately discontinued at the end of 2017. Its activities were only partially replaced by Ouigo, another SNCF low-cost high-speed rail brand. As a result, iDTGV is best understood as a discontinued SNCF sub-brand whose importance lay in experimenting with online-only ticketing, advance purchase, differentiated onboard atmospheres and ancillary paid services within French high-speed rail.
History
iDTGV emerged as an SNCF low-cost high-speed rail concept built around a different commercial and service model from the conventional TGV offer. Rather than treating the train primarily as a standardized transport product, the brand combined online-only distribution, advance purchase and onboard segmentation. The service was operated by SNCF through a wholly owned subsidiary and ran TGV services on multiple French high-speed lines. Its sales process was a defining part of the concept. Tickets were available online, with booking opening as far as six months before departure. The model supported lower promotional fares and reduced dependence on conventional station-based sales channels. Ancillary purchases, including seats and selected onboard services, could also be handled through the website. The emphasis on digital booking anticipated later low-cost and digitally managed rail products, while the advance-purchase structure allowed the service to offer lower prices to passengers willing to plan ahead. The onboard product was deliberately differentiated. Each train was organized into two atmospheres: iDzen and iDzap. iDzen was intended to provide a quiet environment, with restrictions on mobile-phone use and loud conversation. iDzap offered a more relaxed and sociable setting suited to families and holidaymakers, including food service at intervals. This arrangement allowed SNCF to address different passenger expectations within the same train rather than offering a single uniform cabin experience. First-class travel added wider seats, more legroom and access to electrical power. The brand also extended beyond the train journey itself. Catering was provided through a buffet car on applicable train configurations. Passengers could rent tablets containing films and games, with headphones available for use during the journey. In the Île-de-France region, iDTGV partnered with Navendis to provide iDcab, a pre-booked taxi service intended to connect rail travel with local ground transportation. Seat selection and other service modifications were handled through the online booking system, although changes could require a new ticket printout. The service's low-cost identity was also reflected in its baggage policy. The referenced description gives passengers an allowance of one hand-luggage item and one suitcase, with charges for additional bags. This was more restrictive than the baggage arrangements associated with standard TGV services and illustrates how iDTGV used rules and paid extras as part of its cost structure. The network operated from Paris to a range of French destinations, particularly in the south, and the referenced account states that it served 12 French stations. Although the service was associated with some European destinations in secondary descriptions, the available reference material establishes France as its operating market and does not provide a reliable complete list of international routes. At the end of 2017, SNCF discontinued iDTGV. The service was only partially replaced by Ouigo, which became the group's principal low-cost high-speed rail brand. iDTGV therefore occupies a transitional place in SNCF's commercial history: it was a discontinued experiment in online-only rail sales, fare-led demand management, service personalization and paid extras, and it helped establish concepts later associated with low-cost high-speed rail in France.

iDzapOnboard service environment
iDzap was the livelier iDTGV carriage atmosphere, aimed especially at families, holidaymakers and other leisure travelers. It allowed more noise and conversation than iDzen and included food service at intervals. The concept made passenger atmosphere a visible part of the product design.
