1. A power supply for a model railroad layout, comprising:
- an AC transformer arranged to provide an adjustable-voltage AC track power signal and a fixed AC accessory voltage signal;
a pass device coupled to the AC transformer for controllably phase modulating the fixed AC accessory voltage signal to form an altered AC accessory voltage signal;
a relay arranged for connection to a model railroad track, the relay coupled to the AC transformer to receive the adjustable AC track power signal, and coupled to an output terminal of the pass device to receive the altered AC accessory voltage signal; and
a microprocessor, the microprocessor having a first output arranged for controlling the pass device for controllably phase modulating the AC accessory voltage signal for encoding a desired digital command word, and the microprocessor having a second output for controlling the relay for switching between the AC track power signal and the altered AC accessory voltage signal.

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.

2. A method for use in a model railroad locomotive comprising:
-
providing a smoke generator disposed at a first location in a model railroad locomotive; coupling the smoke generator to an on-board micro-processor in the model railroad locomotive for controlling the smoke generator; and under control of the on-board micro-processor, distributing smoke generated by the smoke generator to a second location in the model railroad locomotive, the second location spaced apart from the first location, for controllably simulating an emission of smoke or steam from the second location. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
