Wireless DCC sound decoders and signals for railway modelling

Add interactions and automation to your layout without boosters, additional wiring, command stations, and CV programming. Works with scales N, TT and H0.

How it works Products

How do Wireless DCC Decoders Work?

1

Install a train decoder

Install a decoder into a train (we call our train decoders "Wireless Command Control / WCC train module")

2

(Optional)Connect layout elements

Connect signals, switches, displays and other layout elements to an accessory decoder (we call our accessory decoders "Wireless Command Control / WCC accessory module")

3

(Optional) Put tags on a train or tracks

Tags are wireless and unpowered 8 mm x 8 mm stickers that help to track train position. Tags can be mounted on trains as well.

4

Create interactions and automation in the web app

Change decoder functions, settings and logic directly from your web browser. No command stations required. For example, you can "tell" a decoder to display a message on a station display #2 if a train #4 cross a tag #5

Schematic how wireless DCC work for model railway

That’s it. Control your trains, layout accessories, and create interactions using the web application for Win, Linux, Mac, iOS, and Android or 3rd-party wireless throttles.


Main features

  • - Two-way wireless communication between all decoders - trains, cars, and layout elements "talk" with each other

  • - Decoder functions, CV, settings, and logic can be changed directly from a web browser

  • - No boosters, additional wiring, command stations and CV programming required

  • - Can run on DC, AC tracks and a battery

  • - No vendor lock-in anymore - WCC is an open protocol with clean documentation, code and hardware examples for Arduino

  • - Loco.Engineering decoders can be used with classic DCC systems, so you can buy one decoder and try it on your current layout

  • - OEM and the white-label app even for small model train manufactures

  • - The easiest and probably cheapest way to convert your DC layout to DCC

  • - Over-the-air sound and firmware updates - you shouldn’t remove the train case to update sounds and firmware

  • - Everyone is able to create custom controls and throttles

  • - Low-cost - sound decoders cost €50 or $55. You don't need any additional tools to control decoders or to program them.

  • - Designed, developed, and produced in our workshop in the EU. Zero outsourcing and full control of development help us to deliver updates and new features very often.

  • - Updates and new features every week, fast friendly support

FAQ

How much does it cost?
The estimated price on DCC train decoders with sound is €50, tags - €1, accessory decoders with sound - €60, car modules - €60 (+ VAT on orders from EU countries).
Where can I find documentation about WCC protocol specification and API?
Check our Knowledge Base and feel free to contact us if you still have questions
Is it an open system?
Sure everybody will be able to use WCC open protocol and API to create their own WCC train, car and layout modules, remote controls and mobile/web apps. Check our documentation for more information.
Where can I buy Loco DCC decoders and tags?
Loco.Engineering train, car and accessory decoders will be available at our online store from November, 2023. Subscribe here to be notified when modules and tags are available.
How many trains and layout elements can I connect simultaneously?
You can connect and control up to 32,767 devices (trains, layout elements, signals, displays etc) within one network (or project). If you need more just create two networks.
How far can commands reach?
WCC protocol is based on a mesh network. This means that each train or layout module should be placed as far as 15 to 50 meters from the last.
How many layout elements can I connect to an accessory module?
Check the accessory module webpage to get current module's specifications
