Three approaches to simulating a rail rapid-transit system are compared. The system is itself partly continuous in nature (equations of motion, for example) and partly discrete (dispatch of trains, for example). The three approaches are (1) a basically continuous model modified to accept discrete events, (2) a basically discrete model modified to accept representations of continuous portions, and (3) a combined model designed to accommodate both the discrete and continuous parts. The third approach, combined simulation, is described in detail and is illustrated by its application to an 8-train system. The value of simulation for designing rapid transit systems and analyzing their problems is discussed. The benefits of combined simulation as compared to discrete and continous simulation are enumerated. As an example, all three methods for modelling a simple station exchange process are presented.
