During Germany's re-armament prior to the Second World War several sidings were built to serve military bases (Scheuen, Bergen) which caused a sharp rise in traffic. From 1940 the line was no longer handled as a light railway but as a public railway due to standardisation of the Reich's regulations. This was reflected in the company's new name: the Celle-Soltau, Celle–Munster Railway (Eisenbahn Celle-Soltau, Celle–Munster).
