The purpose of this study is to analyze the effect of cooling by the water atomization in the train base with ventilation equipment. We examined the characteristic of the water atomization by the experiment that changed the quantity of water and the ventilation volume. The temperature descent by latent heat of water mist was 2℃ at velocity 0.3m/s quantity of water 18.4L/h, 3℃ at velocity 0.3m/s quantity of water 36.8L/h, 1℃ at velocity 0.6m/s quantity of water 18.4L/h, and 2℃ at velocity 0.6m/s quantity of water 36.8L/h. The evaporative efficiency has close relation to the ventilation volume and the quantity of water. On the same quantity of water the evaporative efficiency tends to improve so that velocity is fast.
