Ballast: what is it and why do we clean and ... - Network Rail

As the ballast pieces grind together over time through normal wear and tear, it creates fine pieces of granite, like sand. When these ‘fines’ combine with water in the ballast, they stick together: this makes drainage more difficult and the ballast less flexible, therefore less able to restrain the track as trains move over it.

Undercutting | Loram

Undercutting Maintenance of the ballast layer directly below the ties is an essential part of a healthy track structure.

Track ballast - Wikipedia

Track ballast should never be laid down less than 150 mm (6 inches) thick, and high-speed railway lines may require ballast up to 0.5 metres (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions, overloading the soil causes the track to sink, usually unevenly.
