Ballast is the name for the ‘stones’ beneath the track. This aggregate forms the trackbed and supports the track. 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.
