We have been working on expanding our train automation system.  The video below provides a glimpse of the (near) future.  In this video we control everything from a tablet: switches, traffic lights, train head lights and the train itself... The layout automation system is connected to a PC that runs nControl, the tablet interfaces with the PC using a remote desktop app like TeamViewer.  The train uses a prototype of our WiFi based train controller.  The train communicates with nControl using nControl's internal MQTT server.  The track switch motors and controllers are available; the traffic lights should become available the first weeks of April.  The train controller is in development: the goal is to be able to control the direction, speed, head lights, check the battery power, and use a position sensor so nControl can track the position of the train on the layout. Let us know what you think!
