The Kaliningrad Tatra trams are unusual in having bow collectors, rather than pantographs.  Meter gauge system - so German. In 1999 Kaliningrad bought 12 ex-Cottbus Tatra KT4D trams.. Ex-Potsdam KT4Ds also were in service. The T4 is a narrower version of the T3. Sold to the Soviet Union as T4SU vehicles.
