Railway tracks are laid on iron sleepers (also known as rail ties) because they provide strength, durability, and stability to the track structure. Iron sleepers can withstand heavy loads and resist deformation, which helps maintain the alignment of the tracks over time. Additionally, they offer better resistance to environmental factors, such as moisture and temperature changes, compared to wooden sleepers, making them a preferred choice for modern railway systems.
Wooden sleepers are placed below railway tracks to provide support and stability to the rails. They help distribute the weight of trains, maintaining proper alignment and preventing deformation of the track. Additionally, wooden sleepers absorb vibrations and reduce noise, contributing to a smoother ride and extending the lifespan of the railway infrastructure. Their durability and ability to resist environmental factors make them a common choice in railway construction.
