Like all Traxx models from PIKO, the EU43 of Przewozy Regionalne features sharp engravings, capturing every detail of the bogie covers with the axle bearings and spring elements. The body, including the flaps, fan grills, handrails, as well as the roof with the lines and pantographs, was modeled after prototypes and intricately engraved. The printing and painting correspond to the prototype. The locomotive is powered by a powerful motor, with cardan shafts and gears on all four wheel sets. The light changes from white to red depending on the direction of travel.
