Altaria (rail service)
From TrainSpottingWorld, for Rail fans everywhere
Altaria is the brand name of the regular rail service operated by the Spanish national railway company Renfe connecting Madrid to Algeciras, Alicante, Barcelona, Cádiz, Cartagena, Huelva, Irún, Logroño, Pamplona, and Vitoria.
Altaria trains use Talgo technology to enable them to run on different track widths: both conventional Iberian broad-gauge (1668 mm) track and the narrower international standard-gauge (1435 mm) track used for high-speed lines in Spain, as well as for the majority of lines in the rest of Europe.
