The diversity of Germany’s regional railways prior to 1920 is evident in the autonomy of major state railways and regional networks, such as those in Bavaria, Prussia, Oldenburg, and the Palatinate. This landscape was complemented by the Imperial Railways in Alsace-Lorraine, which were the first railways to be directly subordinate to the German Empire.
