Rather comically referred to as Ducklings, the Renfe Class 130s

are technically impressive trainsets being multi-mode as well as dual gauge. In fact, they can change gauges whilst moving relatively slowly thus able to take advantage of both the standard and Iberian (1,668 mm) gauges. They are not as fast as some of the other Renfe trains but they are far more versatile. 130 025 waits to leave Barcelona Sants station with the 17.30 to Madrid taking the coastal route via Valencia.
