A probably unique photograph of the "Adler" taken around 1851, and probably the only one in existence, is in the Nuremberg city archives ("Stadtarchiv Nürnberg"). However, neither the age of the photograph is documented definitely nor is known if the picture shows the original locomotive or only a model. The second class passenger wagon No 8, built in 1835 and rebuilt between 1838 and 1846, was preserved because Ludwig I of Bavaria is supposed to have travelled in it. In 1925 the establishment of the Nuremberg Transport Museum was planned. It was decided that the "Adler", which had been scrapped in 1855, should be reconstructed. The exact plans from that era were lost. Only one engraving from the time of the historical "Adler" provided information. In 1929 these plans were halted by the Great Depression. To celebrate the centenary of the railways in Germany in 1935, a replica of the "Adler" was built beginning from 1933 by the Deutsche Reichsbahn in the Kaiserslautern repair shop ("Ausbesserungswerk"), which was largely true to the original. The original idea of the President of the Reichsbahn Julius Dorpmüller and the members of his staff was to use the "Adler"-replica as an instrument of propaganda for the ""new era"" in the city of the Reichsparteitag Nuremberg. They planned to contrast the "Adler" with modern gigantic steam locomotives like the high-speed DRG Class 05. For the realisation of the replica they used the results of the planning in 1925. Besides of different technical data the replica differed from the original with thicker boiler casing and additional cross bracings and spokes wheels made of steel. The replica attained an average speed of 33.7 km/h in tests on an 81 kilometre stretch of line. The route had gradients of between 1:110 and 1:140. From 14 July until 13 October 1935 visitors could travel with the reconstructed "Adler"-train on a track length of two kilometres on the area of the centenary exhibition in Nuremberg. On the driving cab were also the President of the Deutsche Reichsbahn Julius Dorpmüller and the Gauleiter of Franconia Julius Streicher. The "Adler"-replica was in use after that in 1936 at the Cannstatter Wasen in Stuttgart and during the 1936 Summer Olympics in Berlin.
