Abstract: A plural output control station for operating electrical apparatus, such as model electric train engines and accessories. The control station employs a data processor for monitoring and controlling the signals generated at a plurality of transformer-driven power output terminals. An exemplary station includes two variable-voltage alternating current (AC) output channels (TRACK 1 and TRACK 2) and two fixed-voltage AC output channels (AUX 1 & AUX 2). The variable-voltage outputs are controlled by a data processor responsive to respective operator-controlled throttles for varying the AC output voltage and therefore the rate of movement and direction of electric train engines, typically three-rail O-gauge model trains. The variable-voltage outputs can also be offset by the data processor with positive and negative DC voltages for enabling engine functions such as horns, whistles and bells.
