An IC service to Hamburg, leaded by two 210 (former 218) engines, waits for departure in Berlin Zoo station in March 1997.
At the end of this train, an electric engine of series 120 is carried to Nauen, where the 210 engines will leave the train.
For the rest of the journey (under electricity), the train will be pushed by the 120, a steering-car is already behind the diesel engines.
