This Renfe class 130 train, nicknamed “Mini Pato” (Mini Duck), made by Talgo is capable of speeds of up to 250km/h on standard gauge 25kV AC lines, and up to 220km/h on Iberian gauge 3kV DC lines. The current stretch of track between the gauge changer, and Castelló de la Plana has been newly constructed or reconditioned to allow for 220km/h operation.There is a variant of this train, class 730, that has diesel generators in carriages behind each power car, supplying traction current for the train on unelectrified tracks. It still has pantographs to run on electrified sections.There have been successful trials in the North West of the country to see if speeds of 300km/h can be reached safely on Iberian gauge lines, but it would require large amounts of investment into changing signalling, amongst other things.
