the commonly used railway ballast types. Track ballast should never be laid down less than 150 mm (6 inches) thick; and high-speed railway lines may require ballast up to 1 ⁄ 2 metre (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions overloading the get price
