I would like to add a trolley bus to my model railroad as an eye-catcher, but I am afraid of the expense of a complete installation. Do you have any solution?

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.
