Why Are There Stones Along Railway Tracks?

Track ballast, the crushed stones lining railway tracks, serves multiple purposes. It holds sleepers in place, distributes load, dampens vibrations, aids drainage, prevents vegetation, absorbs noise, and minimizes heat expansion. These stones are jagged to interlock and maintain stability. Regular maintenance is crucial to ensure effectiveness, as dirt can impair drainage. Track ballast is vital for the safety and comfort of railway systems worldwide.
