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, you 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 is 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!
