  Protective measures have already been established against heavy rainfall for embankments to predict the collapse of slopes and control the entry of trains into dangerous spots. In order to secure safe and stable transport, however, it is necessary to implement train operation control more appropriately in rainfall. For this purpose, it is important to grasp the moisture behavior in embankments during and after rainfall, in order to correctly evaluate the danger of collapse, and reflect the result of evaluation in train operation control. In this research, a waterspraying experiment is conducted by using a model embankment which imitates a railway embankment to grasp the moisture behavior in the embankment in rainfall for different values of the permeability of embankment material and when the slope of the embankment is waterproofed.
