Altaria trains were composed of locomotive-hauled Talgo coaching stock equipped with gauge-changing technology which enabled the carriages to run on both conventional (1,668 mm (5 ft 5+21⁄32 in) Iberian gauge) track and the narrower international 1,435 mm (4 ft 8+1⁄2 in) standard gauge track which is used for the newer high-speed network in Spain. Altaria trains were able to achieve speeds of up to 200 km/h on the high-speed lines.

Since 22 June 2022, the brand was replaced by the InterCity services along with other Renfe brands.^[2]
