Avant (train) in the context of "Alvia"

High-speed railways in Spain have been in operation since 1992 when the first line was opened connecting the cities of Madrid, Córdoba and Seville. Unlike the rest of the Iberian broad gauge network, the Spanish High-speed network mainly uses standard gauge. This permits direct connections to outside Spain through the link to the French network at the Perthus Tunnel. High-speed trains run on a network of high-speed rail track owned and managed by ADIF (Administrador de Infraestructuras Ferroviarias), where the dominant service is AVE while other high speed services such as Avant, Alvia, Avlo, Euromed, Ouigo España and Iryo, as well as mid-speed (InterCity) services also operate.

AVE trains are operated by Renfe, the national passenger high-speed rail operator in Spain, but other companies such as Ouigo España and Iryo compete on the Madrid–Barcelona and other routes in accordance with the European Union legislation. French TGV services run from the border to Barcelona under the TGV inOui brand. Alvia and Euromed trains are also operated by Renfe and have the ability to use both Iberian gauge and standard gauge lines offering high-speed services across the whole Spanish network.
