Abstract

A model train and layout control system based on on-board sound and locomotive modules, new signaling methods, bi-directional communication, environmental sound, turnout control, train location methods, computer interaction and accessory control, by adding components to existing technology. AC power signal waveforms are variously altered to convey digital command words.
