Set of two double-deck carriages, type DBmue, manufactured by VEB Waggonbau Görlitz.

■ Prototype version
■ One-off edition with certificate

In 1971, VEB Waggonbau Görlitz delivered two prototypes of the double-deck single carriage to the DR. The double-deck single carriages were expected to allow for more flexible adaptation to fluctuating passenger volumes as well as cost savings in the event of damage. Following extensive testing of the two prototypes, an initial series of around 138 vehicles was delivered from 1974 onwards.
