Double-decker bus DDH 200

The DDH 200 was a modern attempt to reintroduce double-decker buses to Vienna. Built in 1977 by Gräf & Stift as a one-off, it was tested on line 13A. Despite numerous technical improvements, it remained a prototype – its use in Vienna's urban traffic was simply too impractical. Today, the DDH 200 is a popular exhibit at the Remise Transport Museum.
