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

    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.

  • Railroad Ballast, Types And Purpose

    Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also allowing for flexibility when trains pass over. Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength.

    Down below the trains, below the rails, the tie plates, and the ties, is a lowly yet vital component of railroading track ballast. While ballast may not be at the top of anyone's list of rail topics, it's literally part of the foundation of railroads, and it can comprise more than 80% of the weight of the track structure.

  • Railway track ballast-a brief history RAILSCOT

    The recommendation to install a siding was first made in a letter to the Deeside Railway Co. Board of Directors by their Resident Engineer, John Willett C.E.:“Aberdeen 26th November 1862 We are in want of Ballast on some parts of the Extension, and before we can do anything it will be necessary to put a siding into the ballast pit at Crathes.” BR/DEE/1/3 By the time of the 1863-64 survey

  • Towards better understanding of railway ballast CNRS

    SNCF engineers have been using mathematical models for many years to simulate the dynamic behavior of railways. These models have not been able to take into account large portions of the track have been extremely limited at modelling ballast, the gravel layer located under railway tracks. This is why SNCF Innovation & Recherche asked for help from specialists in wave propagation for all types

  • Uses of Aggregates in Construction, Roads, Railway

    Railway ballast generally consists of a tough igneous rock (crushed), such as granite, with a larger diameter varying between 30mm to 50mm. Particles finer than this diameter in higher proportion will reduce its drainage properties. While a higher proportion of larger particles result in the load on the ties being distributed improperly. Other uses include fills, backfills, and drainage and
