Function of Ballast in Railway Track Civil Lead
Ballast may be defined as a layer of broken stone, gravel, moorum or any other material placed under and around the sleepers to distribute the load from the sleepers to the formation and for providing drainage as well as providing lateral and longitudinal stability to the track.. Function of Ballast In Railway Track
Why Is Ballast Placed On Railway Track
17.10.2017· Track ballast should never be laid down less than 150 mm (5.9 inches) thick; and high-speed railway lines may require ballast up to 1⁄2 metre (19.7 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. Ballast less than 300 mm (11.8 inches) thick can lead to

Ballast for railway modellers comes in many sizes and colours. You will need to choose the size dependant on the scale of your model railway, and the colour because of what was used at the location of your railway. Size is really important as over or under size ballast just looks wrong. Colour is not as important as variations occurred around the country dependant on what local stone was
Why Is Ballast Placed On Railway Track

Why There Is No Ballast on High Speed Rail Track?
Ballast is one of the main components in the railway transportation system, used to support the railway sleeper and rail track. Before laying tracks, a layer of ballast is needed to pave on the railway subgrade. The use of ballast is very available for water drainage and the track position adjustment.
12. Railway track ballast Geological Society, London
Railway track formations generally consist essentially of a layer of coarse aggregate, or ballast, in which the sleepers are embedded (see Fig. 12.1). The ballast may rest directly on the subgrade or, depending on the bearing capacity, on a layer of blanketing sand.
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.
Materials for Railway Ballast on the Railway Track
Broken stone is one of the best materials for railway ballst to be used on the railway tracks. Almost all the important railway tracks are provided with broken stone. The stone to be used as railway ballast should be hard, tough nonporous and should not decompose when exposed to air and light.
