Powerful, compact, and yet extremely delicate, this new construction from PIKO is presented. The squat design of the prototype has been perfectly captured and scaled into the model. Thanks to the intricate bar frame and the unobstructed view in the engine area, the massive boiler appears to almost float. This impression is further supported by the fine wheel stars of the chassis, which also features a delicate brake linkage. The typical structural characteristics of the prototypes have also been taken into account in the model's implementation. The crystal-clear window inserts of the driver's cab and the unobstructed interior allow a view of the detailed boiler and cab back wall. The zinc die-cast and metal parts give the model a very high weight, which, in combination with the finely tuned motor with flywheels, ensures optimal driving characteristics. The factory digital versions come with switchable authentic lighting for the engine and the driver's cab. The flickering in the firebox can also be digitally controlled. The Expert Plus model additionally features digitally switchable couplings and a wheel-synchronized pulsed vaporizer.
