The technical report has been prepared under the Transit Development Corporation (TDC) project 'Ventilation and Environmental Control in Subway Rapid Transit Systems.' The underplatform exhaust system is a subway environmental control feature designed to remove train generated heat within the confines of stations and thereby improve environmental conditions. To evaluate the performance of this system, a full-scale test facility was constructed in a station of the Toronto subway. This report describes the facility design and the experimental program. A presentation of test results and interpretations is included, leading to the development of a quantitative design versus performance relationship for use by subway environmental engineers.
