Abstract

To minimize risk from passengers and emergency rescue teams in occurrence of an event of the release of toxic agents or a fire scenario, an understanding of the dispersion process inside subway systems is valuable information. To gather knowledge about the airflow conditions in the subway system of the Tyne and Wear Metro in the centre of Newcastle upon Tyne, air velocity and tracer gas dispersion were obtained during a nightly experiment in the absence of train movement. Results indicate that dispersion ways and passenger routes often overlap.
