ÃÂD Class 680 are high-speed 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 BÃ Âeclav to Brno on November 18, 2004, the Pendolino reached a speed of and created a new Czech railway speed record. The units are able to operate on , and 3,000 V DC.
The initial Czech order for tilting trains was placed with Fiat Ferroviaria during 2000. As part of the Alstom take over of Fiat Ferroviaria the order was changed to Pendolino trains. The first set was delivered in 2004 as Pendolino ÃÂD 680.
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.
The seven car units are composed as:
Cars are individually numbered, with the driving motors carrying their numbers on the nose.
Pendolino is used primarily for the SuperCity train service, which is the fastest train service of ÃÂD.
In December 2006 Czech Pendolinos were given permission to operate in Slovakia and Austria.
In 2009 and 2011, one pair of ÃÂD 680s operated as SuperCity Slovenská strela between Prague and Bratislava. However, it was cancelled due to a low demand, since the train was not actually faster, but more expensive.
As of 2020 ÃÂD Pendolinos operated nine trips a day in each direction on the SuperCity train service under the name SuperCity Pendolino which is running the Prague-Pardubice-Olomouc-Ostrava route, with some continuing to BohumÃÂn and one continuing to the Slovak city of Koà ¡ice under the name SuperCity Pendolino Koà ¡iÃÂan. Twice a day the service is as extended as an InterCity train from Prague to Frantià ¡kovy Láznàvia Plzeà Â.
