Abstract

See full text

A model train accessory controller is connectable to a DC power pack having a throttle to apply a power signal to a set of train tracks. The controller includes a switching device, which is in electrical communication with the power pack and the train tracks, to reverse a polarity of the power signal on the train tracks. The controller includes an input, and a processor in electrical communication with the switching device. The processor receives a command from the input to produce, by control of the switching device, a digital command having a series of sequential reversals in the polarity of the power signal.
