Abandoned telephone exchange

Walk a derelict mid-century exchange built from the Abandoned Telephone Exchange pack: a glazed corridor, a switch hall of racks and distribution frames, the manual operator room, the battery plant and the repair benches, all left mid shift.

About

A 33 by 16 metre exchange from 47 of the pack's 51 models, laid on the pack's own tiled floor bases inside three of its roofed building shells, under the hall preset with the lamps set just below the timber ceilings the shells carry.

You start in the glazed corridor along the south wall, facing a doorway through the operator partitions. Beyond it the switch hall runs 33 metres across: two back to back suites of selector racks and main distribution frames, broken by cross aisles onto each of the three rooms, with the floor trench covers and the supported overhead troughs following the same route and turning down the drop ladders at either end.

Straight ahead is the operator room, closed off by four glazed partitions and the equipment room door. Six manual switchboard bays with their end panels stand against the back wall under the call indicator and subscriber jack fields, headsets, twin cord pairs and a test handset still on the shelves, the chairs pushed back at angles, and the supervisor and directory desks either side with their telephones, call logs, slip trays and book racks. The cord rails, writing shelves, service telephone and bell box run down the side walls.

Off to the west is the power plant and battery room: twenty five cells in tiered rows, four charging cabinets with terminal strips on top, three ringing generators and five fuse distribution boards. To the east are the repair benches, five along the back wall with the resistance box, insulation meter, plug test block, splicing vise and stripped selector assemblies on them, a relay island behind, tool chests under component sorting drawers, and the spare handset cabinets down the wall.

Nothing moves. Every design in this pack is static by intent: the selectors, relays, keys, cords and doors are modelled as they were left, with no call routing, no simulation and no mechanism a rigid node transform could honestly carry. The decay is placed rather than animated, with fallen ceiling panels, mail sacks, chairs and loose paperwork scattered through the corridor, the hall and all three rooms.

Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.

Points of interest

The corridor
A glazed run of operator partitions walls the corridor off the switch hall, with three doorways cut through it. Ceiling panels, mail sacks and chairs lie where they came down.
Glazed Operator Partition (Abandoned Telephone Exchange)
The switch hall
Two back to back suites of selector racks and distribution frames run the length of the hall, split by cross aisles onto each room. The trench covers follow the cable route under your feet.
Selector Equipment Rack (Abandoned Telephone Exchange)
The cable runs
Supported troughs carry the overhead route above the aisle and turn down the drop ladders at each end, terminating on the frames below.
Overhead Cable Trough (Abandoned Telephone Exchange)
The operator room
Six manual switchboard bays behind the glazed partition and the equipment room door, with the indicator and jack fields above them, headsets and patch cords still on the shelves and the chairs pushed back.
Manual Switchboard Bay (Abandoned Telephone Exchange)
The supervisor desk
The rotary telephone, the call log and a slip tray sit where the last shift left them, with the plan board and jack field on the wall beside.
Supervisor Desk (Abandoned Telephone Exchange)
The power plant and battery room
Twenty five cells in tiered rows against the back wall, four charging cabinets and three ringing generators along the front, and the fuse boards above and beside them.
Battery Cell Bank (Abandoned Telephone Exchange)
The test benches
Resistance and insulation meters, a plug test block, a splicing vise and stripped selectors across five benches, with the tool chests, sorting drawers and spare handset cabinets behind them.

Common questions

How do I use Abandoned telephone exchange with my AI development tools?

Press "Copy for AI agent" above and paste the prompt into Claude Code, Cursor, Codex, GitHub Copilot, ChatGPT or any other coding assistant. The prompt carries the direct CDN URL, the real-world size, the licence and the loading notes, so the assistant can fetch the scene and place it in your project without you writing the loader yourself. For a permanent connection, add the 3DAssets.dev MCP server to your tool with one command (for Claude Code: claude mcp add --transport http 3dassets https://3dassets.dev/mcp) and the assistant can then search the whole catalogue, fetch files and read the usage snippets on its own.

How do I get started?

Walk the scene here with the keys or touch to see how the pack fits together. To build it yourself, download the pack with the button, then copy the "Copy for AI agent" prompt: it links the layout JSON, which lists every placement with its position, rotation and CDN URL, so an assistant connected to the MCP server can rebuild the scene in your engine and change it to order.

MCP server setup

Which game engines and tools can I use Abandoned telephone exchange with?

Anything that reads glTF, which today means all of the major ones: three.js and React Three Fiber on the web, Godot 4, Unity, Unreal Engine 5, Blender and the model-viewer web component. Every model in the scene is a self-contained binary glTF (.glb) with textures embedded, so each is one file to import and no plugin, converter or decoder to install first.

How do I import this scene into Unity, Godot, Unreal or Blender?

Unity: install the glTFast package (com.unity.cloud.gltfast) from the Package Manager, drop the .glb into Assets and drag the prefab in, or load it at runtime from the CDN URL. Godot 4: copy the file into the project folder and the editor imports it as a scene you can instantiate. Unreal Engine 5: File > Import with the built-in glTF importer, which converts the axes for you. Blender: File > Import > glTF 2.0. Units are metres with +Y up in the file, and every importer above handles the conversion to its own axes automatically.

Can I use Abandoned telephone exchange in a commercial game, and do I need to credit anyone?

Yes to commercial use and no to credit. Every scene on 3DAssets.dev is released under CC0 1.0 Universal, which places it in the public domain: use it in a paid game, an app, a film or a client project, modify it, redistribute it, and put nothing in the credits. A link back is welcome but it is entirely your choice.

CC0 licence text

Can I load it from the CDN instead of downloading it?

Yes. The pack behind it has a permanent URL on cdn.3dassets.dev that is CORS-enabled and never changes content, so you can pass it straight to GLTFLoader, glTFast or model-viewer in production and cache it as hard as you like. Downloading is only needed for engines that import from disk.

Is the demo itself a file I can download?

No, and it does not need to be. A demo is a layout of the pack's published models composed in your browser from the CDN, so there is no extra file to fetch. Download the pack for the models, and take the layout JSON linked above for the placements: together they are the whole scene, and an AI agent can rebuild it from those two links.

Can I change the scene, or add gameplay to it?

Yes. The layout is plain data in metres, so move, add or remove placements freely in your own engine. Colliders, navigation and gameplay are yours to add: the demo shows what the pack looks like assembled, and your game decides how it plays.
