This is a model of the German State Railroad Company (DRG) narrow gauge steam locomotive, road number 99 221, in the photo gray paint scheme as originally delivered. This is the version with an older design boiler with a feed water heater. The paint and lettering are prototypical for Era II. Two powerful Bühler motors with ball bearings drive all five of the wheel sets. The locomotive has an mfx/DCC decoder with many sound and light functions, such as headlights that change over with the direction of travel, cab lighting, or separately controlled running gear lights. The locomotive has a whistle and bell activated by a reed switch. These sounds will also work in analog operation. The locomotive has a built-in smoke generator with steam exhaust synchronized to the wheels as well as cylinder steam. The locomotive has many separately applied details including a completely detailed cab as well as doors that can be opened. The dual headlights and the large ventilation installation on the cab roof are correct for the era. Length over the buffers 55 cm / 21-5/8".
