The Adler (German for "Eagle") was the first locomotive that was successfully used commercially for the rail transport of passengers and goods in Germany. The was designed and built in 1835 by the British railway pioneers George and Robert Stephenson in the English city of Newcastle. It was delivered to the Bavarian Ludwig Railway (Bayerische Ludwigsbahn) for service between Nuremberg and Fürth. It ran officially for the first time there on 7 December 1835. The Adler was a steam locomotive of the Patentee type with a wheel arrangement of 2-2-2 (Whyte notation) or 1A1 (UIC classification). The Adler was equipped with a tender of type 2 T 2.
The Adler is often cited as the very first locomotive used by a railway company on German soil. But as early as 1816 a serviceable steam locomotive was designed by the Royal Prussian Steelworks (Königlich Preußische Eisengießerei) in Berlin. During a trial run this so-called Krigar locomotive hauled one railway wagon with a payload of 8,000 German pounds (about 4.48 tonnes or 4.41 long tons). But this vehicle was never used commercially. Nevertheless, the Adler was undoubtedly the first successfully operated locomotive in regular use in Germany.
