Drainage of the Railway Track:
It is necessary to keep the embankment free from water. This is done by providing side ditches, all along the edge of the embankment, and leading the water to natural channels. In cuttings, side ditches are equally important. If seepage of water is expected uphill, it is preferable to provide intercepting drains or catchwater drains (Figure).

Cross-drainage structures as discussed in Section 9.5 are constructed along with the earthwork.
