  "notes": "Same 11.8 m module as road-segment-straight and road-intersection-4way. Tileable along X (seams x = +-5.9 m, height field and textures periodic), the meadow edges at y = +-5.9 m also repeat so tiles can be placed side by side. Pivot on the nominal track level like the paved road tiles (z = 0), base -0.20 m. Unique 11.8 m texture set: soil with gravel and stones, compacted ruts with dried puddles and tyre marks, grass with dry patches; grass tufts as real blade geometry along the ridge and the verges. No bottom faces.",
