Looking for digital control of your trains
(and more)?

LocoFi™ provides TRUE independent control of multiple locomotives within the same block with engineer assignments. Not only that, each engineer knows who's running which train.

All this with:

  1. NO change in wiring to your existing DC or DCC layout and minimal to NO wiring for a new layout. Ideal for DEADRAIL!

  2. NO investment in specialized equipment like command stations, boosters or computers that will only get obsolete with time.

  3. ABILITY to run your locomotives at scale speeds on layouts with different track power type (DC/DCC) or voltage (7V - 24V).

  4. EASY to configure and operate intuitive graphical interface.

  5. NO more punching numbers to switch between trains. All trains are visible on your dashboard. Simply swipe with your finger to switch between them.

  6. ONBOARD sounds that are user customizable and separate from cab sounds.

What's more?

  1. First of its kind, ASCL (Auto Stop on Connection Loss) provides the ability of your train to stop itself automatically if there is ever a loss of communication with the controller.

  2. Create speed profiles for different track voltages. When taking your locos/consist to any layout with a specific track voltage, simply switch to that profile and have realistic prototypical operation.

  3. With speed profiles in place, consisting is as easy as 1-2-3.

  4. Loco configuration is all GUI based with touchscreen toggles and sliders that makes it super easy. No more punching numbers or turning knobs.

  5. Ability to support high bandwidth. Useful for video transmission.

  6. Cab sounds from smartphone and not from the locomotive. Only sounds that you hear from the locomotive while standing outside at a distance come from the locomotive.

  7. Onboard sounds are user customizable without needing any specialized hardware. Simply edit the open source format .WAV sound files using free software like Audacity and upload from your computer onto the removable microSD that comes with the LocoFi™ module. Third party sound experts are welcome.

  8. NO unrealistic sounds that only sound cool but not experienced in real life.

  9. Use of various sensors present on your smartphone to provide one of the best tactile feedback and control.

  10. FREE OTA updates means no need to change hardware to get the benefits of new features.

  11. If tinkering is your forte, implement your own app software or even your own firmware.

Sounds too good to be true?

Benefits of using LocoFi™:

  1. Simple: Easy to setup. Easy to configure. Easy to use.

  2. Flexible: Runs on DC, DCC or battery (deadrail) power.

  3. Customizable sound: Based on open source .WAV format.

  4. Realtime feedback: Bi-directional communication enables real time feedback from the loco e.g. current speed, other trains/engineers on the network, etc.

  5. WiFi based: Being WiFi based enables being part of the IoT realm. Create a network of devices and define events and actions to run your story on the layout.

  6. Cost: No extra wiring or equipment. Period. Most likely, all you need to buy is the LocoFi™ module.

No extra sound decoders needed just to get sound with direct wireless capability. Sound is built right in. It can even be tailored to your liking with simple editing... that's right, simple and... again without needing any extra proprietary equipment.

With LocoFi™, you do have to solder 7 wires to install the module in the loco but there's no mess of wiring to deal with under your table. This should be an easy call to make.

Introducing LocoFi™

LocoFi™ provides simple yet powerful multi-train multi-engineer model train control system with onboard sound without any extra equipment like command stations, boosters, expensive proprietary handheld controllers or even computers. There's minimum to no wiring at all. All you need is a LocoFi™ module, your smartphone and optionally a WiFi router. The module gets installed in the loco and can be DC or DCC track powered or even battery powered. Since the communication is DIRECT over ubiquitous WiFi protocol, there's no commands that go on the track. This means reduced overhead, less maintenance, less hidden costs that come with setting up a system. It's cutting edge technology utilizing existing hardware in everyone's hands, simple intuitive interface and even customizable sounds. Because of its simplicity and ability to be powered by a variety of power sources from as low as 7V to as high as 24V, your can take your locos (even consisted) around to different clubs without changing a thing. Being primarily a software and WiFi based system, it is updateable over the air so you don't have to miss out on the new features as they roll out. Your hardware remains the same but the functionality keeps increasing. This, no programming based system with haptic controls and pressure sensitive features can easily co-exist independently with other systems on the same layout without interfering at all. It promises to be a system of the future using the in-built IoT to connect to other devices on the network, create a distributed system with embedded powerful processors and high bandwidth to support video streaming, decision making as in artificial intelligence and automation. The bi-directional nature of communication provides real-time feedback, is prototypical in nature and yet even kids can operate it!

"... those who don’t wish to convert a layout to Digital Command Control (DCC), LocoFi ... provides an intriguing option for independent locomotive control as well as on-board sound. ..."

"... app also features so-called “haptic” control, .... This helped me more easily control the throttle without having to look at the screen."

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

The Details

LocoFi™ is 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!
