In 1971, VEB Waggonbau Görlitz delivered two prototypes of the double-decker individual coach to the DR. The double-decker individual coaches were expected to be more flexible in adapting to changing passenger volumes and to reduce damage. After extensive testing of the two prototypes, an initial series of around 138 vehicles was delivered from 1974. The lower floor of this coach was completely equipped with seats. It was first used in the southern urban centres and routes with high traffic volumes.
