Hannover: The brand new cleaning unit is presented at Hannover fair in 1997. Not yet delivered, the car already wears "üstra" marks and a typical licence plate of the Hannoversche Verkehrsbetriebe (H-HV xxx). This Unimog lorry for rails and roads might be described as a large vacuum cleaner. It replaces an older and larger vehicle. Photo by Sven Herzfeld (s.herzfeld@maschsee.han.de)
