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. 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

Railroad Ballast and Other Track Materials

Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or

Research on Railroad Ballast Specification and Evaluation

Quarried stone ballast should be obtained from com­ petent strata of reasonable thickness. The extent of the rock deposit should be sufficient for economic ballast production. A large variety of rock types are used as ballast. In general, the fine hard min­ eral-grained unweathered aggregates make the best ballast.

Railroad Ballast, Types And Purpose

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

How to ballast track World Of Railways

The ballast isn’t just a uniform colour, but has a subtle blend of dark and light stones because ballast often has crystalline or darker impurities. The traditional method of fixing ballast is to apply a 50:50 ratio of PVA and water, with a drop of washing up liquid.

Tamping machine Wikipedia

A tamping machine or ballast tamper is a machine used to pack (or tamp) the track ballast under railway tracks to make the tracks more durable. Prior to the introduction of mechanical tampers, this task was done by manual labour with the help of beaters. As well as being faster, more accurate, more efficient and less labour-intensive, tamping machines are essential for the use of concrete

Why build slab track? Britpave

Experience with use of ballast at high speed (350 kph) has shown that fine particles can be sucked out of the track by the passing train. These particles are deposited on the rail surface and cause damage when run over by the wheels. In some areas this has required use of glued ballast
