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 railway vehicle 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. It had a sister locomotive, the Pfeil.
