Internal Combustion Locomotive

Based on online research and images, this is a hand‑crafted Dongfeng 4B locomotive.
Dimensions are approximately 450 mm × 65 mm × 95 mm (110 mm including the track bed).
The project requires 31 M3×10 screws, 21 nuts (M3×8 or M3×12 will also work), adhesive, and other standard tools.
The decorative trim pieces must be painted; they are not printed as part of the model.
Optional accessories include 1–2 AG1 7.5 mm magnetic control lights.
To ensure structural integrity, most joints are designed to be fairly tight—feel free to slightly enlarge the holes or perform minor sanding as needed.
Please refer to the attached installation files for detailed instructions.
