In 1816, the Royal Prussian Steelworks built a steam locomotive able to complete a trial run of hauling a single wagon along a short course laid out on company grounds. The Krigar locomotive had been designed by Johann Friedrich Krigar. It was not considered a success; the gauge was unsuitable and it was under-powered. The Adler locomotive, an import built by the father and son team of George and Robert Stephenson of Newcastle, England, became the first viable commercial locomotive in Germany. The machine was delivered to the Bavarian Ludwig Railway in 1835, and began hauling passengers and cargo between Nürnberg and Fürth the same year, a distance of less than twenty kilometers. The locomotive typically pulled nine wagons able to accommodate 192 passengers between the two cities at a modest speed of 28 km/h. It remained in service for twenty-two years.
