The railbuses were delivered to the following railways:
Kiel-Schönberg Railway (Kiel-Schönberger Eisenbahn) (one unit)
Kiel-Segeberg Railway (Kiel-Segeberger Eisenbahn) (two units)
East Hanoverian Railways (Osthannoversche Eisenbahnen) (seven units)
North Frisian Transport (Nordfriesische Verkehrsbetriebe) (one unit).

Following the withdrawal of passenger services the railbuses were sold to south German railways or to Italy.
After the six railbuses had been decommissioned in Italy, there were bought in 2000 by the Lüneburg Railway Society (Arbeitsgemeinschaft Verkehrsfreunde Lüneburg or AVL) and brought back to Germany.
Only one vehicle has been scrapped to date, the others still exist, some in working order.
In some examples the engine was removed and they were only used as trailer cars.
In 2010 the following are working:
VT 21 of the Prignitz Railway, (Prignitzer Eisenbahn), sold to the Westphalian Localbahn, (Westfälische Localbahn), ex OHE GDT 0517
