This video is from the screen of an Android tablet, showing NX (Entrance-Exit) operation of a complex area of railroad tracks. With this system, turnouts are set by pressing 2 buttons, or more if selection between multiple routes is needed. On a smooth screen without physical controls, the "buttons" are simply graphical elements. The software is written in RFO Basic. The input is from a text file which encodes connectivity and graphics: in principle, the same software could control any layout. In this demonstration, the layout is the east end of the Tech Model Railroad Club's main freight yard. The west end also uses NX control, but it is a hardware-based system with a microcontroller and a monochrome screen.
Connection to the actual railroad will be by a Bluetooth link, and remains to be built.
