So these crushed stones, called ballast, are used to hold the wooden cross ties that in turn keep the rails in place. You need to understand the entire process here.

To start things, a foundation is built to raise the railway track high enough to avoid flooding. Ballast is deposited atop this foundation. After this, row of 8.5-feet-long, 9-inches-wide, and 7-inches thick wooden beams is laid above the layer of crushed stones.

Almost 3250 wooden beams are laid per mile. The ballast is dumped all around the beams. The wooden beams are kept locked in place by the sharp-edged stones. The entire process of building a railway track isn't easy you see!

Next, the hot-rolled steel rail tracks are laid atop the cross ties, and their ends are welded together via fishplates. The modern railways may forgo the fishplates and weld the tracks continuously. Now we know the importance of those crushed stones.
