Alvia

Alvia is a high-speed train service in Spain offered by Renfe Operadora on long-distance routes with a top speed of 250 kph. 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.

Routes
, RENFE Class 120 / 121, RENFE Class 130 and RENFE Class 730 trains are in service.

Class 120 trains are used on the routes from Madrid to Pamplona, Logroño, Irún and Hendaye (France) (running on high-speed lines from Madrid to Burgos and changing gauge there), and between Barcelona and Irún, Bilbao (running on high-speed lines between Barcelona and Zaragoza).

Class 130 trains are used on the routes from Madrid to Bilbao, Irún, and Hendaye (changing gauge at Burgos), from Alicante to Gijón and Santander changing gauge at León and Venta de Baños, between Castellón and Gijón (on high-speed lines from Castellón to León), and between Barcelona and Galicia.
