{"data":{"id":"11550","slug":"modern-rail-and-metro-network-electric-freight-locomot-d1036303","title":"Electric freight locomotive (Modern Rail and Metro Network)","summary":"A 20.9 m Bo-Bo electric freight locomotive with two pantographs, machine room louvres and a warning panel.","description":"A four axle electric freight locomotive: a 20.9 m lofted body with raked cab ends and wrap-around screens, machine room louvre bands along both sides, a warning panel and headlight clusters at each end, cab access steps and grab handles. Two motor bogies with named wheelsets, an underslung transformer, roof insulators with a high voltage bus, a circuit breaker and two single arm pantographs, one raised and one folded. 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 3.53 x 5.91 x 20.88 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: pantograph-front-lower-arm, pantograph-front-upper-arm, pantograph-front-head, pantograph-rear-lower-arm, pantograph-rear-upper-arm, pantograph-rear-head, bogie-front-axle-1-right, bogie-front-axle-1-left, bogie-front-axle-2-right, bogie-front-axle-2-left and 4 more. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/modern-rail-and-metro-network-electric-freight-locomot-d1036303","cdnUrl":"https://cdn.3dassets.dev/assets/11550/v2/model.glb","downloadUrl":"https://3dassets.dev/download/modern-rail-and-metro-network-electric-freight-locomot-d1036303","thumbnailUrl":"https://cdn.3dassets.dev/assets/11550/v2/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/11550/v2/poster.webp","blurhash":"U45#|r.98^M^W@I8ITof00Mx.9%4I8%%.Aj^","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":400472,"triangles":10052,"vertices":30156,"meshes":24,"materials":8,"textures":0,"animations":["wheel-roll"],"boundingBox":{"min":[-1.764458075875631,4.768371586472142e-9,-10.4399995803833],"max":[1.764458075875631,5.910008833135505,10.4399995803833]},"sizeMeters":[3.529,5.91,20.88],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-06T15:04:49.952Z","updatedAt":"2026-09-07T11:57:56.635Z","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/11550/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 ElectricFreightLocomotiveModernRailAndMetroNetwork(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/11550/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/11550/v2/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/11550/v2/model.glb\" alt=\"Electric freight locomotive (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/11550/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/11550/v2/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
