The oldest locomotive in Germany, where is it? It still lies buried under several meters of gravel in the old riverbed near Germersheim, waiting to be awakened from its sleeping beauty slumber after more than 160 years. Finding it again after such a long time was an exhilarating adventure for passionate treasure hunters. It took more than two decades of intensive research to develop a viable treasure map. In parallel, 14 geophysical measurement excursions were conducted to ultimately capture a valid geomagnetic footprint of the Kessler locomotive 205. Many questions arose: How did the shipwreck on the Rhine in 1852 occur with the locomotive on board? How do you find a 20-ton iron object hidden underground? Where exactly is the find site? Who owns this locomotive today? When and how will the locomotive be raised?.
