In 1965 German Deutsche Bundesbahn developed a six axle electric loco for fast passenger service. The unique design made the E03 (later 103) for the most famous German electric loco. All sample of the three designs reached a maximum speed of 200 km/h. Although they were developed only for light trains the 103 succeeded in heavy intercity service for more than 30 years. Engineer/driver mode: Engineer/driver mode switch on with CV170 = 1, Engineer/driver mode switch off with CV170 = 0)
The Engineer/driver mode serves as a prototypical control of the train. The realistic start up process and the current-dependent processes are activated.
***Please note! In Engineer/driver mode, the train only reacts when one or both pantographs are up***
Heavy load operation:
F13 - Activates heavy load operation. The acceleration now takes noticeably longer and the electric motors work harder.
Braking functions:
F17 - Brake function 1 with brake valve sound. Trains brakes to a standstill.
F19 - Brake function 2 with brake fan sound. Downhill simulation (speed reduction with CV179 and CV182 adjustable). Train significantly reduces the speed.
Radiator fan automatic:
F20 - In standstill and radiator fan button off:
1 x press = radiator fan step winter / 3 x short press = radiator fan step summer / 2 x short press = stop radiator fan run-on after driving while stationary. If radiator fan button is permanently active = radiator fan remains in radiator fan step winter until button is switched off.
F20 - While driving and radiator fan button on: Radiator Fan button pressed = radiator fan step winter or summer (depending on the speed or forced activation) remains switched on and the button is switched off. Press twice = switch from radiator fan step winter to radiator fan step summer (depending on the speed or forced activation)
*** Attention: After switching on while driving from radiator fan step winter to summer, the step summer remains switched on until radiator fan function is switched off! ***
Deactivate braking Sound:
F27 - Deactivates brake squeal Sound when the train stops. (4 different brake squeal sounds with CV165 value 0-3 selectable)
F18 - Station Announcement #1: Announcements selectable via CV169: (0=randomized Announcement, 1=Ulm, 2=Cologne, 3=Mainz, 4=Munich, 5=Mannheim, 6=Salzburg, 7=Stuttgart, 8=Dortmund, 9=Duisburg, 10=Augsburg)
Additional function: direction switch, E03/BR103 long version, selectable with CV168 = 1
