Coal Stage

Locomotive coaling stage: a raised timber-decked platform 8 x 4 m on brick piers with the deck 2.5 m above ground for tipping into tenders, steps up one end, a hand jib crane at the track edge on a jib knob swinging out over the track.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
