Deutsche Reichsbahn (East Germany)
The Deutsche Reichsbahn or DR (German Reich Railways) was the operating name of state owned railways in the German Democratic Republic (East Germany).
In 1949 occupied Germany's railways were returned to German control after four years of allied control following World War II. Those in the Soviet occupation zone (which became the German Democratic Republic or GDR on October 7, 1949) continued to run as the Deutsche Reichsbahn, the name given to the German national railways in 1937. In West Germany, the Reichsbahn was succeeded by the Deutsche Bundesbahn (DB).
Both the Reichsbahn and the Bundesbahn continued as separate entities until 1994, when they merged to form the Deutsche Bahn.
