The Döllnitzbahn GmbH is a private railway company in Saxony in eastern Germany.
The primary aim of the company was initially the preservation of the remaining goods traffic from the kaolin mine at Kemmlitz.
With the help of used PKP diesel locomotives, they succeeded initially in keeping the goods traffic going.
The Döllnitzbahn was the last narrow gauge railway in Saxony to run public freight services.
Today only school trains and steam-hauled 'specials' run on the Döllnitzbahn railway, e.g. for touristic purposes.
