FIELD: ventilation.
SUBSTANCE: method involves moving of air with moving trains through the circulation ventilation connection connecting the tunnels near the subway station, and through the station. To create the desired air flow through the subway station from moving trains in the tunnel and its regulation depending on the frequency of train movement, the aerodynamic drag of circulation ventilation connection is changed.
EFFECT: lower economic costs for the ventilation of tunnels and subway stations.
