In the first service of Chapter 5 - Mixed Bag - S1 Meißen Triebischtal - Dresden I appear to be given the task of bringing the train into service in the early morning. I am placed in the cab of a BR143 but am then given 3 minutes to reach the station 2km away. Just turning on the minimum of reverser, lights and brake key, I can't reach the station in time. At the other end of the train is a BR 146. Both the 143 and 146 have pantographs raised. Is this formation correct? The next service in the journey from Dresden gives me a cab car with a 146 at the rear.
