A track bed is the foundation or base structure on which railway tracks are laid. It consists of layers of materials, such as gravel, sand, or crushed stone, designed to provide stability and support to the tracks. The track bed helps distribute the weight of trains evenly, preventing the tracks from shifting or sinking over time. It also allows for proper drainage, ensuring the tracks remain safe and functional, even in wet conditions. The track bed is an essential part of the railway system, maintaining the strength of the track and supporting smooth train movement.
