toy steam locomotive 3d model

Compact stylized toy steam locomotive for a casual mobile puzzle game. Very simple clean geometry, short body, low height, wide enough to read clearly from a top-down 3/4 camera. Small rectangular cabin at the rear, short rounded boiler in front, one small simple chimney, flat front face, three small wheels on each side. Wheels must be smaller than the body height and clearly separated from the body for animation. No realistic mechanical rods, no undercarriage detail, no extra pipes, no couplers, no rail track, no environment, no scenery, no text. Smooth rounded edges, polished low-poly mobile game style, toy-like proportions, visually similar to a premium casual puzzle game. Neutral grey material only so the whole train body can be recoloured red, blue, green, yellow, purple, or orange in the game. Centered at world origin, straight orientation, clean GLB-ready geometry.
