April 2, the French national train company SNCF launched a new brand for low-cost high speed trains. The new trains are called Ouigo, and marketed as distinct from the regular TGV trains. The new brand was created with French agency Carré Noir, who have previously worked on SNCF's corporate identity. The name "OUIGO " can be interpreted as a combination of the French word for yes (oui) and the English word go, a fairly simple message. This simplicity is also expressed in the visual identity programme, with simple pictograms, a clear logo and friendly pink and blue trains.
