The DABuzfa 778 double-decker driving trailers have 29 1st class seats and 64 2nd class seats. Both first and second class offer seats on the upper level, lower level, and at the ends of the coach. Thus a PMR-compliant access for both classes at platforms of approximately 550 mm above rail level is guaranteed.
The coaches have a permitted top speed of 120 km/h. The boarding area is approximately 600 mm above the rail level and is therefore suitable for the requirement for low-floor boarding.
The driving trailers are equipped with 34-pin discrete push-pull train controls of Deutsche Bahn, as well as conventional push-pull train controls.
DABuzfa 778 double-decker driving trailers are typically used in train combinations together with DBuza 747 or DBuza 749 double-decker centre coaches. Currently, the double-decker coaches are often used with electric locomotives, less often with diesel locomotives, such as the BR218, as well.
