模型火车不但是精致的收藏品，其外形也完全根据各国各年代火车缩小仿制而成，具有真实性和历史性，而外壳大多由高级工程塑料ABS塑成，内置精巧电机，金属压重，全按比例缩小。铁道也根据真实铁道比例缩小，用锌合金拉制而成，电流通过控制器传达至铁道后带动车头马达，模型火车就会如同真实火车一样运动，可调速前进、后退，如有电灯也会发亮或跟随火车行驶方向的转换而转换电灯方向，有些也可外加音效或烟效如真实火车般栩栩如生。

Model trains are not only exquisite collectibles, but their appearance is also completely scaled down and imitated based on the trains of various countries and eras, with authenticity and historical significance. The outer shell is mostly made of advanced engineering plastic ABS, with exquisite motors built-in and metal weights, all scaled down proportionally. The railway is also scaled down according to the actual railway proportion, made of zinc alloy. The current is transmitted to the railway through the controller and drives the locomotive motor. The model train will move forward and backward like a real train, with adjustable speed. If there are electric lights, they will also light up or change the direction of the lights according to the direction of the train's travel. Some can also be equipped with sound or smoke effects, which are as lifelike as real trains.
