Railway basics
The track is the roadway of track-bound vehicles laid in a ballast bed, consisting of rails, rail supports (usually sleepers) and rail fastening devices. Track branching Track branching is the name given to the branching of a track from one (or more) main line track(s), made by means of points , crossings or crossing points .

EVALUATION OF THE ENGINEERING BEHAVIOUR OF RAILWAY BALLAST
The ballast layer is the most important component of the railway track infrastructure. It is subjected to both the traffic load and the exposure to environment changes. In consequence, the ballast bed deforms and degrades highly affecting the performance of the railway track. Therefore, it is imperative to investigate in detail the deformation

QUARRYING FOR RAIL BALLAST
quarrying for rail ballast The porphyry quarry at Quenast in Belgium was recently redeveloped and enhanced to be able to produce about 2Mt per year. Its new quaternary crushing and final screening section now ensures that about a third of the quarry''s output meets TGV and Belgian and Dutch rail specifications.

Permeability, Resistivity and Strength of Fouled Railroad Ballast
However, ballast deterioration and fouling are major issues in the railroad industry, and can be caused by repeated loadings, which lead to crushing ballast that is in contact with ties. Upward migration of subgrade particles into the ballast layer can increase fouling in the ballast and decrease drainage through the ballast layer.

Track ballast
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

Railway Ballast | Function Of Stones In Railway Track
railway ballast The function of ballast in railway track. 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.

Why There Is No Ballast on High Speed Rail Track?
Ballast refers to the gravel or crushed rock paved on the road or railway subgrade, it is mainly used in railway subgrade. 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.
