  • 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) This approach has been adopted successfully by Australian railways.
