The rocks are split and have sharp edges so they kinda knit together. They are used under the ties to spread the load and NOT let ties sink into the mud. They also help the ties from slowly moving and shifting out of place and getting skewed over the years. If you are talking about ON TOP of tracks, that is sand dropped from locomotives to help the wheels from sliding. It actually gets crushed into a kind of glass.

Lowers vibration and noise. Also used so the tracks do not sink into the ground when raining or if wet ground. Keeps tracks more in line and on even ground. Costs less to plow a strip and flatten gravel then it does to level ground flat and then pour concrete. Plus the maintenance costs.
The rocks are called 'ballast' and they support the track and keep it from sliding around as the heavy trains roll over the rails. The ballast also keeps the wooden ties (called sleepers in the UK) up off the wet dirt so they don't rot away.
