Tender locomotive D793 of the RAG, Era IV with sound and smoke, DC/AC
Prototype condition around 1972

The finely detailed model is mostly made of metal and features a variety of separately applied parts. It goes without saying that the prototype-specific differences are taken into account. A visual highlight is also the wheels designed with thin spokes.
The model is depicted with largely worn wheel tires, allowing the wheel stars to have prototype-appropriate dimensions. This leaves enough space for the flange to be designed in such a way that safe operation on two- and three-rail tracks is possible. To minimize compromises in the chassis, we guarantee operation only on radii from 420 mm. Since the locomotives were used in local freight and shunting service, they are equipped with a shunting coupling in the standard pocket on both sides.

- Newly designed smoke generator
- Crosshead, slide bar, and piston rod made of metal

Matching hook couplings with non-magnetic hooks are included with the locomotive. Of course, the model emits smoke from the chimney in a wheel- and locomotive sound-synchronized manner, controlled by axle sensors. This makes operating the classic Prussian locomotive a visual and acoustic delight.

Naturally, we paid close attention to the prototype when designing the sounds. For example, during downhill runs, the acoustic can be switched to counter-pressure brake using the function key, mimicking the Riggenbach counter-pressure brake.
The acoustics of the various air and feed pumps were also different. Shunting is done prototypically under the dual lighting of the right lower lantern. In the Prussian variant, the third headlight can be activated to display the head signal Zg 7 (counter train signal).
For the first time in large series, the lanterns are designed to be free-standing, as per the prototype. When coal is acoustically shoveled into the firebox, the firebox lighting also glows.
