WCC (Wireless Command Control) is an open wireless system to operate model railways and LEGO® trains. WCC can run on DC, AC, or a battery and includes just 2 components:

  • Train and layout modules to control trains and layout elements (signals, switches, etc). More info about how WCC modules work
  • Unpowered NFC stickers (optional but they give more options for interactions)

How to start

  • Check this guide
  • Order a WCC train or element module
  • Receive a module, connect to a train or layout elements
  • Create the first interaction or just control your train or layout elements manually using Loco.Engineering web app

Main features

  • Up to 10000 trains and layout elements within one network
  • No boosters, additional wiring, and command stations are required, WCC works even on DC or a battery
  • Open protocol - everyone can create hardware, firmware, and apps
  • No WI-FI router is required
  • 2-way communication between trains and layout elements
  • No CV programming required - create interactions and layout automation in the web app or use scripting language for more complex logic
  • Get the exact location of the trains with unpowered rail stickers (works in the same way as  real trains - https://en.wikipedia.org/wiki/Eurobalise)

Examples of use cases

WCC allows you to create really complex interactions and automation to give more life and realism to your layout. For example:

  • You can show different messages on a station display depending on which train is arriving
  • You can add a fully automated train block system to your layout
  • You can create a virtual train timetable and trains will move according to it
  • You can automate all your signals, barriers, and switches without command stations, boosters, and additional wires

What's next?

  • Check documentation for more details about WCC
  • Order a WCC module, receive and create your first project
  • Create your first app using API
  • Develop your own WCC hardware module based on WCC protocol
