"... Good-running locomotives are a primary requirement for enjoying operations ..."

"... shows the potential that LocoFi holds for becoming an alternative to DCC ..."

What is LocoFi™?

LocoFi™ consists of WiFi enabled LocoFi™ decoder module with onboard sound that you install in your locomotive and control using the FREE LocoFi™ app on your smartphone or tablet.

LocoFi™ provides multi-user, multi-train control of your locomotives by directly communicating using WiFi without involving the track. It's based on the paradigm shift where how you control your locomotive is separate from how you power it.

With separation of power and control comes:

  1. Simplification: The interdependence of power and control signal makes the system complex. Moreover, a direct connection means less number of intermediary components, leading to further simplification.

  2. Performance: Dual powerful micro-controllers, high communication bandwidth and the powerful computer in your hand can deliver unparalleled performance. Imagine real-time cab view streaming of an ops session or giving control to operate your railroad from across the world!

  3. Ease of Use: Everyone loves interactive rich user interface. Graphical interface of smartphone makes management, operation and configuration of your loco a piece of cake leaving you to focus and enjoy true operations like load simulation, grade simulation, braking, etc. and literally puts you in the engineer's seat.

  4. Security & Reliability: The underlying security, robustness and reliability of WiFi need no mention.

  5. Scalability: Software managed approach with powerful hardware and innovative ground up approach design leads to scalability.

  6. Real Time Feedback: Bi-directional communication provides real time monitoring and usage statistics about your loco. This feedback mechanism can be exploited to being more prototypical operation.​

The onboard sound is user configurable and stored on a removable microSD card. The sounds are in non proprietary format and easy to edit giving users the option to either use their own recordings or third party provided sounds without binding you into manufacturer provided proprietary sound formats. Just like scenery, trackwork or electronics, this just opened up yet another aspect for modelers to explore!

All this with:

  • X NO boosters or command stations

  • X NO additional wiring

  • X NO computers

  • X NO custom proprietary throttles

  • X NO CV programming

LocoFi™ hardware virtually never gets outdated

Keeps evolving with Over The Air firmware updates!

No more taking out the decoder and sending it in for upgrade.
