Eschede derailment
The Eschede derailment occurred on 3 June 1998, near the village of Eschede in the Celle district of Lower Saxony, Germany, when a high-speed train derailed and crashed into a road bridge. 101 people were killed and 88 were injured. It remains the worst rail disaster in the history of the Federal Republic of Germany and the worst high-speed-rail disaster worldwide. The cause was a single fatigue crack in one wheel that, when it failed, resulted in a part of the wheel becoming caught in a set of points, effectively changing the setting of the points whilst the train was passing over it. This led to the train's carriages going down two separate tracks, causing the train to derail and crash into the pillars of a concrete road bridge, which then collapsed and crushed two coaches. The remaining coaches and the rear power car crashed into the wreckage.
