VENT AND STATION TEST (VST) FACILITY SINGLE AND DOUBLE TRACK STATION TESTING

The report concerns ventilation and environmental control in subway rapid transit systems and is one of many leading to a subway environmental design handbook. The report is to present test data generated in the VST facility for single and double track stations. Pressure signatures for various stations with and without mezzanines, for various entry portals, vent shafts and platform configurations are presented and compared to a DSI generated theory. Circulation patterns for the various configurations are presented and recommendations are made.
