The corner post of the station kit: a 0.46 m square concrete column 3.5 m tall on a spread base, with a rusted cap band and four external tie rods at its arrises. It is wider than the 0.28 m wall bays, so two runs stopping at each other's inner face meet inside it with nothing sharing a plane. Dimensions 0.66 × 3.50 × 0.66 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Static geometry; no rig, animation, collision or navigation data.
