On Saturday, April 26, southbound ICE 885 derailed within the Landrücken tunnel on the Fulda-Würzburg high speed corridor. The train, which was carrying 135 passengers, was travelling at over 200 km/h or 124 mph, when it ran into a herd of sheep which had escaped from an adjoining pasture and wandered into the tunnel portal. Ten of the twelve self-propelled cars including the front cab derailed. Nineteen passengers were injured, 4 seriously. DB officials stated that it was a stroke of good luck for the passengers that the train derailed while entering the tunnel, as the train scraped along the right-hand side of the tunnel, remaining aligned parallel to the track as opposed to jack-knifing into one another.
The tunnel wall and roadbed were both seriously damaged, although no major structural damage was done to the tunnel. High speed passenger trains are being detoured, adding 40 minutes delay to the Hamburg-Munich journey as well as delaying local passenger and freight trains on the alternate route, which was already operating at near capacity.
