- Ballast is a layer of crushed stone or gravel that is used to support and level railway tracks. It is a vital component of the rail transportation system and serves several purposes, including:
Stability: Ballast provides stability to the tracks, which allows trains to run safely and smoothly.
Drainage: Ballast provides drainage facilities for the track.
Weight distribution: Ballast distributes the weight of the train and track on the subgrade, which reduces vibration and noise.
Heat dispersion: Ballast disperses the high heat generated when a train passes by.
Weed prevention: Ballast has strong permeability and prevents the growth of weeds on the track.
