The locomotive has a frame, superstructure, tender and applied parts constructed mostly of metal. This is a highly detailed model with many separately applied parts, Wagner smoke deflectors and a detailed engineer's cab. The locomotive has an mfx digital decoder, controlled high efficiency propulsion and a sound generator with operating sounds synchronized with the wheels as well as extensive sound functions. It can be operated with AC power, DC power, Märklin Digital or DCC. There is a built-in smoke unit with smoke exhaust and cylinder steam synchronized with the wheels. The dual LED headlights have a light color correct for the era and change over with the direction of travel.

It comes with a reproduction of the prototype coupler on the front and a claw coupler on the rear of the tender. An accessory package with a reproduction of the prototype coupler, a claw coupler plus engineer and fireman figures is included.
