Steam locomotive T 9.3 in the version as TKi3 of the PKP in epoch III.  In terms of design, the Expert steam locomotive leaves hardly any room for wishes and takes into account all the structural and visual features of the prototype locomotive, such as PKP lamps, enlarged coal box, the true-to-original line routing on the boiler or fine die-cast metal spoke wheels in typical PKP colours.  By retrofitting a PIKO digital decoder, the lighting in the drivers cab and running gear area can be switched. In addition, a digitally switched, flickering LED in the area of the firebox simulates the red glowing coals. All of the lighting, including the light change in the direction of travel, is designed using modern, maintenance-free LED technology. The PIKO model is also prepared to be equipped with a vehicle sound.
