Open Goods Wagon

6 m four-wheel open goods wagon: planked sides with side drop doors on a doors knob (shut or dropped), steel underframe with leaf springs, axleboxes and a brake lever, wheels turning on the rig; a load knob of empty, coal.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
