Abstract
An electronic control system for model railroads incorporates a motor control unit, an electronic state generator that generates particular operating state signals responsive to multiple reset conditions. A first reset condition initiates sequencing of motor control states and a second super reset condition independently controls system initialization conditions increasing the overall number and accessibility of controller generated operating states.
