The first train in Germany ran on December 7, 1835 between the cities of Nürnberg and Fürth. This rail line was only 7.45 kilometers / 4.66 miles. It became famous as the Ludwig Railroad and had its roots in a railroad project developed a few years earlier that was quite revolutionary for the times. The "Privileged Ludwig Railroad Company" was founded in November of 1833 and was granted a concession from the Bavarian King Ludwig I on February 19, 1834 to build and operate the railroad. Horses and a steam car were planned to be available for operation. Originally, the steam car was supposed to be built in Germany, but a reliable builder could not be found. Therefore, an order for the first German "steam car" was quickly placed with the father of the steam locomotive - George Stephenson in Newcastle upon Tyne, England. The order was not placed until May of 1835 and after an eight week, very arduous trip the new steam locomotive arrived in Nürnberg on October 26, 1835, but disassembled in over 100 pieces and packed in 19 large crates. The locomotive was immediately assembled under the expert direction of the English locomotive engineer William WiIson "delivered" with the locomotive. It was named after the "Adler" or "Eagle" as the heraldic animal of the Kaiser and the free imperial cities. The purchase of the cars was simpler. Two frames had been delivered from England, and the home "industry" built the car bodies as well as another seven passenger cars. The locomotive was built on a wood frame strengthened with sheet metal. Two inboard, vertical wet steam cylinders powered the driving axle located in the middle. The driving wheels had no flanges in order to enable the locomotive to negotiate sharp curves. The wheels were initially made of cast iron (later forged iron) and were surrounded with forged tires. The forged, hollow wheel spokes were given a wood core in order to cushion unevenness better. Braking was done with the help of a spindle brake, which only worked on the tender wheels on right side of the fireman. Initially, charcoal, then later hard coal was used as fuel. The approximately 6.5 metric ton "Adler" turned in excellent results right from the start. Its performance was around 40 horsepower and its speed when running by itself was 65 km/h / 40 mph. It could pull up to twelve cars. After 22 successful years of operation retirement caught up with it in 1857 and soon after that it was scrapped. Starting in 1933, the DRG had a reproduction built largely true to the original for the 100th anniversary of railroading in Germany in 1935. This was done at the maintenance facility in Kaiserslautern and included the cars to go with the locomotive. In addition to differences in technical data, the reproduction differed from the original chiefly in a thicker boiler wall for the sake of safety, additional transverse bracing, and spoke wheels made of steel. This was the steaming "Adler" reproduction at the one hundred year anniversary, 25 years later at the 125th anniversary, and, after being overhauled, the 150th anniversary of the first years of railroading in Germany. The operational reproduction of the Adler was heavily damaged, among other locomotives, in a fire at the museum depot in Nürnberg-Gostenhof on October 17, 2005. The DB's board of directors decided to restore it however. At least 80 percent of the original parts from 1935 could be used again for the restoration. In the process the new "Adler" became even closer to the prototype in details than the burned up locomotive. For example, the reconstruction of the smoke stack did not follow the reproduction of 1935 but was closer to the original. Only the two burned up cars built largely of wood had to be built completely from scratch. The new "Adler" as well as an old (1935) and two new (2007) passenger cars have been located since November 23, 2007 in a locomotive shed again close to the DB Museum in Nürnberg.
