The built-in charging current limiter would make charging a Goldcap last far too long. The component would lose the desired effect.
In general, Digi-Trolley™’s steering system is completely different from the vintage Eheim-/Brawa models. Digi-Trolley™ cannot be operated without a wire in the roadway.
The dimensions of the Eheim-/Brawa overhead lines are considerably different from those of the Digi-Trolley™, so a combined operation is impossible.
In an analogue environment, the electronics is responsible for a constant brightness even at low voltages.
In an analogue system, the controller is responsible for constant brightness. Once adjusted, its impact during operation can no longer be changed. The speed of the model is controlled independently of this electronics via a joystick box outside the model.
In a digital system, a driving decoder controls the driving speed as well as other additional functions, like switching sth. on or off (eg direction indicators), dimming sth. (eg interior lighting) or volume controlling (moving vehicle).
To optimize the power supply and to ensure the most quiet and smooth ride, Digi-Trolley™ is supplied with an ‘anti flicker capacitor’ by default. If this component doesn’t do a job good enough, you may add additional capacitors yourself (depending on the available space in the model). Be aware, however: If the overall capacity of these parts is too high, other components may be damaged.
All components that are necessary for the operation of the Digi-Trolley™ are available either as individual parts or as a conversion kit.
Both a digital and an analogue design are planned.
The analogue version is powered by 16 V AC or DC. The digital version supports only DCC.
In addition to operational models, illuminated non-functional models will be offered. The power supply for the interior lights, driving lights and direction indicators is realized through the overhead line – just as in the operational models.
These standing models have no engine and no electronics and are therefore considerably less expensive than full-featured models. These models are also well suited for crowding a trolley bus depot.
Market launch was scheduled for early 2016. Unfortunately, due to severe difficulties in the production of peripherals, there is a delay by some years. Right now, we are confident to show a running model in 2020.
Update: The Corona pandemic is expected to postpone the market launch by one year.
