WCC vs Others

WCC vs DCC projects

WCC is a new look at how we can operate model trains, cars, and layout elements. WCC is a new protocol and doesn't depend on DCC. Main advantages:

  • two-way communication between trains, cars, and layout elements
  • over-the-air firmware updates
  • no programming is required
  • WCC modules can execute user's scripts to run complex interactions
  • no signal wires are required
  • works on DC, AC or a battery


Feature WCC DCC
Communication 2-way between trains, cars, and layout elements one-way
Connection Wireless (Mesh network) Wired
Supply DC, AC or battery AC
Position accuracy up to 1 cm no positioning
Over-the-air updates yes by default only BLE decoders
Programming Optional using scripts Required
Sound In train and accessory modules, over-the-air custom sounds Only built-in sound
Automated train block system Built-In Required a lot of time and knowledge, expensive

WCC vs Roco Z21

Roco Z21 is a digital control system (hardware + software) that controls trains and layout elements using DCC. You still should think about all DCC stuff - wires, CV programming, and boosters. WCC is a fully wireless system and you should connect WCC modules only to DC, AC, or a battery.

WCC vs Blunami

Blunami is a DCC decoder with Bluetooth. You can control a train directly from the iOS app but you cannot create any interactions without DCC. That means you still should think about signal wires, CV programming, boosters. WCC is based on mesh networking with 2-way communication between trains, cars, and layout elements and you can create realistic and complex interactions just with 1 WCC train module and a few WCC unpowered tags.
