The Ústí nad Labem derailment occurred on 28 June 2010 when a CityElefant train derailed at Ústí nad Labem, Czech Republic.

The train involved was a ČD Class 471 CityElefant double deck electric multiple unit[1] that had been manufactured in 2001.

[2] At 16:47 CEST, the train was derailed on approach to its final scheduled stop, Ústí nad Labem hlavní nádraží, in the southern suburb of Vaňov.

The line, which forms part of an international railway corridor linking Prague and Berlin, was closed following the accident, although one track was later reopened to traffic but requiring the use of diesel locomotives as the overhead wiring had been damaged.

[2] Although investigations are still underway,[needs update] it has been already reported that at the time of the crash, the train was travelling at 108 kilometres per hour (67 mph) while the speed limit at that location was 50 kilometres per hour (31 mph).
