Railbus

Four-wheel diesel railbus about 12 m over buffers, a light single car for the branch: a cab at each end with a wide windscreen, a long row of passenger windows, two-leaf passenger doors each side on a doors knob, underfloor engine and fuel tank, roof exhaust.

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
