Duchy of Brunswick
The Duchy of Brunswick State Railway was the first state railway in Germany. The first section of its Brunswick–Bad Harzburg railway line connecting Braunschweig and Wolfenbüttel opened on 1 December 1838, as the first railway line in Northern Germany. In the 1870s, the Duchy of Brunswick State Railway merged with the Royal Prussian State Railways. Some other railways of secondary importance were operated by the Brunswick State Railway Company, founded in 1884.
