Before you call up the national government in Berlin: The Kingdom of Bavaria is history. The magical anniversary number refers to the date of the crowning, when the Bavarian Prince Elector, with the favor of Napoleon, styled himself in 1805 as King Maximilian Joseph I. The cultural flowering then began under King Ludwig I, who was succeeded by Maximilian II, and the Fairy Tale King Ludwig II. What makes this history so interesting for us are the Royal Bavarian State Railways, which we have to thank for some of the most beautiful prototypes around. We are celebrating the anniversary with a one-time series of the articulated Mallet locomotive, the class Gt 2x4/4.
