Open wireless platform to control trains, layout accessories (signals, level crossing), and any movable vehicles on a layout


Recommended Posts


Hi everyone. I’m working on a new open wireless platform to control trains, layout accessories (signals, level crossing), and any movable vehicles on a layout. I call it WCC (wireless command control). Every decoder communicates with other decoders over the air that’s why you need just plug DC power into your layout. No command stations and boosters are required - just install a decoder inside a train or connect a decoder to a signal, open a browser on your laptop or mobile device and you can already control your layout. DCC is still can be used in case you already have a layout with DCC.

I would like to get your feedback, and ideas to know what features should be included at the beginning and what later. The protocol will be fully open with code examples so users who like to code can develop their own decoders and controllers. WCC decoders will be available from December 2023 - January 2024, documentation about the protocol with code examples on Arduino and how to develop your own decoder will be available in December as well.

Below you can find more details about how it works, a schematic, and a photo of a decoder prototype - production candidate (currently the size is 11 x 39mm, after we release the main version, we'll add special versions for Kato). Also, you can get more info at https://loco.engineering

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

- Detect train location and add complex interactions with NFC tags (for scale N NFC tags (5 mm x 5 mm) should be placed on a train, and readers (small circuits) should be placed under rails)

- 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 manufacturers

- The easiest and probably cheapest way to convert your DC layout to the interactive layout

- 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. 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

It'll be interesting to see if this takes off or how well it works.  Good luck!     I'd be interested in adding support to an iPhone/Mac control app I am writing, eventually.

Thanks for posting. For my Japanese steam locomotives, it'll be nice if smaller than a Blunami BLU-2200 decoder, easier to install and hopefully much less expensive.

Currently we're waiting for PCBs for the final version. Hope everything will be available from June on our website
