 note = {The results obtained from the field tests on the ventilation of air in a tunnel caused by the piston-action of a train running through it are reported in this paper. In the tests the wind-velocity at the exit of a blow-hole as well as at the exit of the tunnel was measured and the ventilation efficiency of air was calculated.
According to the results of the tests, the ventilation efficiency does not depend on the velocity of the train. Rather, it was found that the larger the number of cars becomes, the larger the ventilation efficiency becomes. On the other hand, it also increases slightly by the presence of a blow-hole.
Finally, it is expected that less than forty percent of the air in a tunnel is ventilated while a train is running through the tunnel.},
