This new construction from PIKO presents itself as powerful, compact and yet extremely filigree. The penetrative design of the prototype was perfectly met and converted into the model to scale. Thanks to the filigree barrel frame and the clear view in the engine area, the massive boiler seems to be almost hovering. This impression is supported by the fine wheel stars of the chassis, which can also come up with a fine brake linkage. The typical constructional features of the models were likewise observed in the implementation in the model.The crystal-clear window inserts of the driver's cab and the unspoiled interior leave a view to the detailed boiler and cab back wall. The die-cast zinc and metal parts give the model a very high net weight, which provides for optimal driving characteristics in combination with the finely tuned motor with flywheel masses. The factory-digital variants have a switchable authentic illumination of the engine and the driver's cab. Similarly, flickering in the fire box can also be digitally switched. The Expert Plus model also possesses digitally switchable couplings and a wheel-synchronously controlled, pulse evaporator.The model carries the quality mark fit mfx®. In order to ensure that digital decoders can be used reliably for all users of the current Maerklin digital centers, a new quality mark fit mfx® was introduced together with Maerklin and other manufacturers. This can only be used by digital decoders that have passed a special mfx® test.These decoders and also the locomotives in which they are installed carry the quality mark fit mfx®, which certifies the unrestricted mfx® functionality. This means that PIKO products with the fits mfx® logo now fully support the many and varied functions of mfx®.This text is machine translated.
