The DL6 was delivered by Diema to the Office for Land and Water Management in Heide in 1959. Purchased by a private individual in Wedel in 2003, the locomotive was sold on to the Deutsches Feld- und Kleinbahnmuseum in the same year. In 2021 the locomotive was repainted and completely repaired and put back in operation.

The locomotive is equipped with a semi-automatic transmission.
