A laboratory model incorporating a microprocessor-based system to control signals and points and to monitor track circuits is described. Approach locking and backlocking controlled through a programmable timer are included. The model consists of a control panel with entrance-exit type control, namely, a switch and a pushbutton for each route. Light-emitting diodes take the place of signal lamps. Points are simulated by means of three position-neutral polar arrays. A method of reducing the probability of accidents associated with this type of control is presented. It consists of duplicating the input channels and utilizing redundant input data.
