Abstract: A designer-oriented computer program, designated the Single-Track Subway Environment Simulation model, has been developed to simulate multiple train operation in a single-train subway and to provide continuous peak, and average readings for the air velocity, temperature, and humidity throughout the stations, tunnels, and ventilation shafts. The program also provides continuous calculations of the location, velocity, and acceleration of the train(s) moving through the system. This program is intended for use in evaluating the influence of tunnel geometry, ventilation shaft design, and environmental control equipment upon airflow, temperature, and humidity in a subway. The aerodynamic portion of the program has been validated using data from a scale-model test facility.
