Mainline Diesel Locomotive

Big Co-Co mainline diesel locomotive about 18 m over buffers with a cab at each end: two three-axle bogies that pivot on the rig so it sits on any kit curve, wheels turning; slab body sides with grilles and a small window row.

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
