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, the first 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). To seperate them, hydraulic jacks were already placed under the upper half to lift it further.
