WCC train, car and accessory modules

WCC modules receive messages from other modules (other trains, cars and layout elements) and control trains, cars and accessories (more about WCC protocol). A WCC module has SoC (System on a chip) that not just start/stop a train or car, change signal light but also plays sounds, sends messages to other modules, handles received messages and uploads statistics. WCC modules are similar to DCC decoders but with more functions, over-the-air updates, over-the-air sound uploading, custom scripts for more complex logic.

You can order modules at or develop your own modules.

WCC modules

  • Train modules
  • Car modules
  • Accessory modules

Optional WCC submodules

You can connect additional submodules to a WCC module using 4-pin connectors (no soldering required)

  • NFC submodule detects unpowered NFC tags on rails
  • Sound submodule plays sounds and music
  • Real-time positioning submodule sends messages with the current train and car location on a layout
  • Your own submodules based on the WCC protocol

How to get started?

  • Select and order a WCC module at
  • Install and connect the module (a detailed guide can be found in the package with a module or by scanning QR-code on the module)
  • Order and connect optional submodules (NFC, sound, real-time positioning) to the module
  • Open the web application at on a mobile device, tablet or computer
  • Follow instructions in the app to create a project (or layout network) and connect a first module ( you need a Wi-Fi router or Bluetooth device or computer with a USB port to connect a module )
  • You can add new modules to the layout network anytime - click on “Add Module” in the web app
