ČD Class 680 are electric multiple units used in the Czech Republic, using tilting Pendolino technology. Built by Alstom (ex Fiat Ferroviaria) they were largely based on 9-car ETR 470. While testing from Břeclav to Brno on November 18, 2004, the Pendolino reached a speed of 237 km/h and created a new Czech railway speed record. The units are equipped to work on 25 kV 50 Hz AC, 15 kV 16 2⁄3 Hz AC and 3,000 V DC.
