ČD Class 680

ČD Class 680 are EMUs operating in the Czech Republic, using tilting Pendolino technology intended for the SuperCity train service. Built by Alstom (originally Fiat Ferroviaria), they were largely based on the nine-car ETR 470. While testing from Břeclav to Brno on November 18, 2004, the Pendolino reached a speed of 237 km/h (147 mph) and created a new Czech railway speed record. The units are able to operate on 25 kV 50 Hz AC, 15 kV  16.7 Hz AC and 3,000 V DC.https://web.archive.org/web/20150215091853/http://spz.logout.cz/novinky/novinky1.php?rok=2003&mesic=6
==History==
During the testing period, the train had problems with the Czech signaling system. The problems were reported to have been solved and the trains entered regular service in December 2005 between Prague and Ostrava. As of late January 2006, all five of the in-service trains suffered from software and operating problems, ranging from failing air conditioning and heating to malfunctions of the tilt controls. The supposedly ERTMS-compliant ATLAS control system is unable to properly connect several discrete systems, each based on different software platforms. Similar problems have also been reported with the Finnish VR Class Sm3. All problems were fixed.
