Glantalbahn
In the postwar period, the line was affected by damage as a result of the war, especially in the form of long travel times. In 1920, the Glan Valley Railway between Homburg and Jägersburg became part of the newly created Saar, which was controlled by the United Kingdom and France for a period of 15 years as a League of Nations mandate. This meant that Waldmohr station had customs and border controls. With the founding of Deutsche Reichsbahn in the same year, it took over the Glan Valley Railway to Schönenberg-Kübelberg and the Saar Railway ("Saareisenbahn") was responsible for the remaining section to Homburg.
