2015/12/30 In addition to these two types of sub-ballast, a full-scale box was utilised with the aim of analysing the effect of these layers on the mechanical performance of railway track sections. This box, shown in Fig. 1, had a length of approximately 750 mm, a width of 440 mm, and a height of 500 mm in order to reproduce the railway structure from the bottom of the sub-ballast layer to the ...

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

What is ballast? 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. 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 ...

Ballast – Functions and Types

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.
