Delivered in 1963, this locomotive was used as CDL 20 on the Bad Schwalbach moor railway (then spa railway) until 1985 (Schöma factory number 2699 built in 1963). The locomotive was traded in to Schöma in 1985 after gearbox damage, overhauled there and sold on to Klasmann-Werke GmbH in Bockhorst as CHL20G. In the 2000s, it was acquired by a private individual from Wedel, who sold it to the DFKM.

The locomotive has a 3-cylinder 4-stroke diesel engine with hydrostatic drive and electric starter. The locomotive was refurbished in 2022. It is ready for operation.
