Gravel, Crushed Rock, Cinder: The Importance of Ballast in Railroad Beds
What are gravel, crushed rock, and cinder used for in railroad beds?
a) To provide stability to the tracks
b) To serve as a decorative element
c) To enhance the speed of the trains
Answer: a) To provide stability to the tracks
Gravel, crushed rock, and cinder are essential components used as ballast on railroad beds to provide stability to the tracks. Without this ballast, the tracks could shift, leading to potential accidents and damage to the infrastructure.
Ballast serves as a foundation for the railroad ties, keeping them in place and preventing them from moving. It also helps with drainage by allowing water to flow away from the tracks, reducing the risk of erosion and other water-related issues.
Furthermore, ballast helps distribute the weight of the trains evenly, reducing the pressure on the tracks and allowing for smoother and safer travel. It plays a crucial role in maintaining the overall integrity and functionality of the railroad system.
