Railway Ballast Function Of Stones In Railway Track

2020-6-4  Ballast is a common trackbed structure in the railway transport system, which is used to support track sleepers. A layer of crushed stones will be laid on the roadbed before the tracks are laid, which will then be compacted. Then sleepers and tracks will be laid. Distribute the pressure of the sleepers to the roadbed.

Railroad Ballast (Rock): Specifications, Sizes, Background

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).

Ballast Size - Model Railways On-Line

What size is prototype ballast ? On Britain's railways, prototype ballast is a grade of different stone sizes, ranging from half an inch (12.7mm) to 2 inches (50.8mm), evenly graded. The reason a mixture of sizes is used is so that the stones lock against sleepers and each other to hold track in place without movement.
