{"data":{"id":"11543","slug":"modern-rail-and-metro-network-high-speed-trailer-car-ae8d1486","title":"High speed trailer car (Modern Rail and Metro Network)","summary":"A 25.7 m high speed trailer car with gangways at both ends, eight window bays and plug doors.","description":"The intermediate trailer car for the high speed formation: a 25.7 m lofted body with tapered ends, a matching skirt and glazing band, eight saloon window bays, a plug door at each end of each side and rubber gangway bellows on both ends. Two trailer bogies with three brake discs on each axle, an underfloor equipment raft and two roof air conditioning packs. Wheel flanges rest on y=0 so the rail plane sits at y=0.03; place the vehicle at y=0.57 over a track module to stand it on the railhead. Automatic coupler ports sit at each end at y=1.07. Bounding size 2.93 x 4.31 x 25.66 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: door-r1-a, door-r1-b, door-r2-a, door-r2-b, door-l1-a, door-l1-b, door-l2-a, door-l2-b, bogie-front-axle-1-right, bogie-front-axle-1-left and 6 more. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/modern-rail-and-metro-network-high-speed-trailer-car-ae8d1486","cdnUrl":"https://cdn.3dassets.dev/assets/11543/v2/model.glb","downloadUrl":"https://3dassets.dev/download/modern-rail-and-metro-network-high-speed-trailer-car-ae8d1486","thumbnailUrl":"https://cdn.3dassets.dev/assets/11543/v2/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/11543/v2/poster.webp","blurhash":"UAATl^xuV@xu-=8_M{xu009Fxvt79F~q-;M{","category":{"slug":"vehicles","title":"Vehicles"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"}],"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":298192,"triangles":7184,"vertices":21552,"meshes":20,"materials":6,"textures":0,"animations":["open","close","wheel-roll"],"boundingBox":{"min":[-1.4659854791414715,1.19209286886246e-9,-12.829999923706055],"max":[1.4659854791414715,4.309081962172565,12.829999923706055]},"sizeMeters":[2.932,4.309,25.66],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-06T15:04:47.779Z","updatedAt":"2026-09-07T11:57:54.214Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\nimport { AnimationMixer } from 'three'\n\nlet mixer\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/11543/v2/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n  mixer = new AnimationMixer(gltf.scene)\n  mixer.clipAction(gltf.animations[0]).play()\n})\n\n// Call from your render loop; deltaSeconds is time since the previous frame.\nfunction updateAssetAnimation(deltaSeconds) {\n  mixer?.update(deltaSeconds)\n}","r3f":"import { useGLTF, useAnimations } from '@react-three/drei'\nimport { useEffect } from 'react'\n\nexport function HighSpeedTrailerCarModernRailAndMetroNetwork(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/11543/v2/model.glb')\n  const { actions, names } = useAnimations(animations, scene)\n  useEffect(() => {\n    const action = actions[names[0]]\n    action?.reset().play()\n    return () => { action?.stop() }\n  }, [actions, names])\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/11543/v2/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/11543/v2/model.glb\" alt=\"High speed trailer car (Modern Rail and Metro Network)\" camera-controls auto-rotate autoplay></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/11543/v2/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.\n# Clips arrive as actions; play them from the Dope Sheet > Action Editor.","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)\nvar player := model.find_child(\"AnimationPlayer\", true, false) as AnimationPlayer\nplayer.play(player.get_animation_list()[0])","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/11543/v2/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
