The Celle-Soltau, Celle-Munster Light Railway (German: Kleinbahn Celle-Soltau, Celle-Munster GmbH) was until 1908 a publicly owned company run by the district of Celle in North Germany and was originally named the Garßen–Bergen Light Railway (Kleinbahn Garßen-Bergen).
With the permission of the Celle–Wittingen Light Railway a solution was found in the shape of a junction on their line.
It was more than two years later, on 13 December 1904, that direct services from Bergen to Celle became possible when the line to Celle-Vorstadt on the Celle–Wittingen railway was opened.
Two years earlier, in 1908 the Celle–Soltau, Celle–Munster Light Railway had been founded as a GmbH, supported by the district of Celle, the Kingdom of Prussia, the Province of Hanover and the districts of Fallingbostel and Soltau, the town of Celle and several villages along the line.
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.
