Ballast base at y=0, concrete sleeper tops at y=0.41 and railhead top at y=0.60; 1,435 mm gauge with rail centres at x = +/- 0.7525. The module origin sits on the rail-a port at the track centreline and the module runs toward +Z on the 6 m grid. Bounding size 5.60 x 2.70 x 6.00 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/modern-rail-and-metro-network-inspection-pit-module-73d800e5","cdnUrl":"https://cdn.3dassets.dev/assets/13711/v1/model.glb","downloadUrl":"https://3dassets.dev/download/modern-rail-and-metro-network-inspection-pit-module-73d800e5","thumbnailUrl":"https://cdn.3dassets.dev/assets/13711/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/13711/v1/poster.webp","blurhash":"U7E:0n_400xa9FRkozj]00IUxtD%?at7%Lt6","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"modular","title":"Modular"},{"slug":"kit","title":"Kit / Set"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":42676,"triangles":808,"vertices":2424,"meshes":5,"materials":5,"textures":0,"animations":[],"boundingBox":{"min":[-2.8000427259132663,0.00008562587675231548,-0.0012000000569969416],"max":[2.801242779522729,2.7009667565777677,6.001200199127197]},"sizeMeters":[5.601,2.701,6.002],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T15:40:43.482Z","updatedAt":"2026-09-07T15:40:43.590Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/13711/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function InspectionPitModuleModernRailAndMetroNetwork(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/13711/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/13711/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/13711/v1/model.glb\" alt=\"Inspection pit module (Modern Rail and Metro Network)\" camera-controls auto-rotate></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/13711/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/13711/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
