Railway Ballast | Function Of Stones In Railway Track

Railway ballast or track ballast refers to crushed stones placed under the railway track. It forms the trackbed for sleepers to lay on. Although some tracks are ballastless, the ballasted track remains a dominant infrastructure of the most railroad tracks. Why is that? Ballast in railway may seem inconspicuous, but its function plays a key role.

Ballasted railway track: reducing maintenance needs

On a modern railway the sources of such fines are much reduced, meaning that the ballast specification could be altered to include a wider range of grain sizes without dramatically affecting its long-term permeability (after allowing for a degree of fouling).
