Loading Gauge

The hoop hung over a goods siding exit to check loads: two timber posts at x = +/-2.4 m carrying a crossbar from which a curved iron gauge bar hangs on chains, its profile exactly the kit's loading gauge (3.0 m wide, 4.2 m above rail top) centred on x = 0.

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
