One of the new low-floor trams in Braunschweig, numbered 9561, in
an unusual orange livery which is possible the beginning of an
advertisement livery. In the middle under each of the three 
carbodies, a special bogie with no axles between the wheels is
located. Similar types are used in other cities too, but the 1100mm
gauge is unique to Braunschweig.
