One half of a derailed articulated auto carrier seen at Aachen West on 18 July 2007. After the first axle of the car (out of the picture on the right) had left the rails, this half of the car moved upon the other with it's buffer (between the two parts there is a special coupling with just one buffer on each side). The seperation required this half to be lifted further by hydraulic jacks, now preparations to rerail it are going on. The girder visible under the end of the car section obviously belongs to a device that is known as Deutschlandgerät in Germany (the name does not come from the country, but from the Maschinenfabrik Deutschland, which was an engineering works in Dortmund and invented this device). It allows to lift a railway vehicle and shift it laterally in the lifted position, using several hydraulic jacks (some of them still missing in the picture).
