  • Track ballast Wikipedia

    A more recent, and probably better, technique is to lift the rails and ties, and to force stones, smaller than the track ballast particles and all of the same size, into the gap. This has the advantage of not disturbing the well-compacted ballast on the trackbed, as tamping is likely to do. [20]

    Rail profile Wikipedia

    The rail profile is the cross sectional shape of a railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section (profile) approximate to an I-beam,but asymmetric about a horizontal axis (however see grooved rail below).

    Because ballast is a large one-size, angular rock, it allows water to drain away from the track. The process of placing the ballast around and under the railroad ties and track is called tamping the track. The ballast supports and levels the track. Ballast also helps keep undesirable vegetation from growing in the tracks

    Silica dust in rail ballast One of the main functions of ballast is to retain track position from forces placed upon on the railway track both from the trains and tamping. When silica containing materials are crushed or abraded e.g. during tamping, or stone blowing, there is the risk that silica crystals can be released in a range of sizes. A proportion of them can be sufficiently small
