This is a model of the class HG 4/4 cogwheel steam locomotive, road number 704, of the DFB (Furka Mountain Line Steam Railroad). It is a finely detailed model with heavy metal construction including many separately applied details. All driving wheelsets are driven via side rods by a powerful motor. Genuine cogwheel for operation with the LGB 10210 cogwheel rack is possible. The doors to the cab and the smoke box door can be opened. The paint scheme and lettering are prototypical for Era VI, or as the locomotive looks today. The locomotive is equipped with an mfx/DCC decoder with many light and sound functions such as headlights, cab lighting, running sounds, whistle sound activated by a reed switch. The locomotive also has a built-in smoke generator with steam exhaust synchronized to the wheels as well as cylinder steam, steam at the exhaust for the vacuum brakes, and steam exhaust at the whistle when the latter is activated.
