Alvia

Alvia is a high-speed train service in Spain offered by Renfe Operadora on long-distance routes with a top speed of 250 km/h (160 mph). The trains have the ability to use both Iberian gauge and standard gauge, which allows them to travel on the recently constructed high-speed lines for part of the journey before switching to the "classic" Iberian gauge network to complete it. Trains that run exclusively on high-speed tracks are branded AVE or Avant.
