Track ballast usually crushed stone as it is known is another important part of railroad infrastructure Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails which is why the stone is always sloped downward and away from track Railroad Engineering 101 Track Crossties Materials Wood Concrete Functions Hold gage and line of rail Transmit train weight from rail to ballast Distributes train weight Provide a base to anchor rail Provide support to distribute load maintaining more uniform cross level of rails
