The HSB 187 016 diesel multiple units are narrow-gauge vehicles operated by the Harz narrow-gauge railways. A total of four copies were built in 1999 in order to be able to operate less frequented routes more efficiently.
 The model is approx. 54 knobs long and consists of approx. 630 individual parts. It is prepared for motorization with a Power Functions train motor, but can also be easily motorized with an old 9V train motor. Both driver's cabs are indicated, the roof can be removed in sections, but the interior has not been expanded.
