AbstractTemperature and air flow measurements in two adjacent stations of the Toronto Yonge Street subway systemindicated average ventilation rates due to train piston action plus fans of between 70ft3/min and 130ft3/min perfoot of tunnel. These rates were enough to limit the average subway temperature to about 11 "F above ambient and to limit the diurnal subway temperature variation to about 1O0F, the ambient temperature varying as much as 20°F. Comparison with approximate theory indicated that the Yonge Street subway is operating near optimum conditions and that reduced ventilation would be deleterious whereas increased ventilation would not be effective in further improving comfort conditions with the existing traffic.
