Ballast: what is it and why do we clean and replace it ...

It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway. The ballast is packed up to, between and around the sleepers, with a ‘shoulder’ of ballast piled up at either end to resist side-to-side movement of the track.

They then lock together less easily, reducing the ballast’s effectiveness. 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.

Railway Track Ballast - Cloburn - UK Wide Delivery!

Granite, such as Cloburn Red, is one of the best materials for the job as it will not degrade under load when wet. Few rock types meet the stringent criteria for modern high-speed railway lines and Cloburn sets the standard for all the rest. Conventional ballast has a tendency to erode/break down over time.

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.

Railroads are required to submit an environmental report to the Surface Transportation Board (STB) when they begin the process of abandoning a corridor. If the STB finds that salvaging the line will result in significant environmental impacts, they can impose conditions on the abandoning railroad requiring them to address the issues before abandonment can proceed.
