Influences of ballast degradation on railway track ...

2021-4-1  Presently, railway track buckling, caused by extreme heat, is a serious issue that causes a huge loss of assets in railway systems. The increase in rail temperature can induce a compression force in the continuous welded rail (CWR) and this may cause track buckling when the compression force reaches the buckling strength.

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).

The track formation is the part of the railway installations that carries the rolling traffic. It forms the carriageway. Technically, the track formation is divided into the subgrade (e.g. an area prepared to compensate for unevenness, if necessary, and the solidified foundation soil) and the superstructure (e.g. ballast and track). The track ...
