FIELD: ventilation.
SUBSTANCE: ventilation system (70) includes air duct located in tunnel and provided with possibility of removal of smoke, gases and hot air (F), which are formed as a result of fire inside the tunnel, and their exhaust to the tunnel outside; on-board fire detection device and position determination device, which are installed aboard the transport vehicle; and electronic control unit. Air duct includes a lot of first air valves, which can be brought into action separately and which, when being opened, connect the inner side of air duct to inner side of the tunnel. When being used, the vacuum created with suction device connected to the air duct is formed in that air duct.
EFFECT: higher protection efficiency of passengers of transport vehicles.
