Unleash your engineering prowess with the 3D Steam Engine Puzzle. Construct a replica of one of the earliest steam vehicles at a 1:28 scale. This model features a compact yet powerful motor capable of driving the model both forward and backward, even with a full trailer attached. The model boasts a manual three-speed gearbox, options for slow or fast forward driving, or reverse. Additional features include a folding sunshade, a steering wheel that turns, and silicon wheels.

Attach the 120-degree swiveling sprung trailer and you're set to haul your cargo anywhere. Lights placed in the firebox and chimney simulate burning, while smoke 'emerges' from the chimney, enhancing the realistic special effects of this elaborately detailed steam engine. The package also includes a period lamp and bench, in addition to the steam engine itself. Note, it requires 2 AAA/LR03/AM4 1.5V batteries, which are not included. The puzzle is shipped in pieces, complete with a detailed assembly guide. Invite your family or friends for a fun building session—no glue or tools needed. All parts are precisely cut to fit together seamlessly, ensuring a stable and durable finish.
