The Renfe Class 102 or S-102 (nicknamed "Pato" in Spanish, because of its nose that looks like the beak of a duck) is a push-pull high-speed train used for the AVE service and operated in Spain by the state-run railway company Renfe, and based on Bombardier Transportation's power car technology. Outside AVE service, Talgo markets this train as the Talgo 350.
Further production of closely related trains, differing in seating arrangement, resulted in the S-112.
