Track ballast - Wikipedia

07/03/2005  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

Ballasted and non-ballasted track - Rail

09/12/2015  CONS: But, as on most tracks, differential settlement in the ballast layer means that regular tamping may be required to maintain track quality. This is exacerbated as train speeds increase, pushing wheel-rail contact forces higher, and therefore a means of reducing the dynamic forces transmitted into the sleepers and the substrate becomes more important and attractive.

Other possible ‘soft’ ballast improvement techniques include gluing, and containment of ballast in fabric wraps or bags (‘ballast bags’). However, there is a complete lack of scientific investigation or understanding of how any of these techniques may influence the behaviour of the track, and how external parameters including train loading and sub-base condition would control their ...

To give a train a good ride, the track alignment must be set to within a millimeter of the design. Track design and construction is part of a complex and multi-disciplinary engineering science involving earthworks, steelwork, timber and suspension systems - the infrastructure of the railway. Many different systems exist throughout the world and there are many variations in their performance ...

Ballasted Track - an overview ScienceDirect Topics

A heavy track structure consisting of heavy rails and ties of great weight (concrete ties) yields less sharply pronounced resonance peaks. Lighter rails are less favorable, the same applies to short ties. Thus, the cross-tie track of the Tokaido system, with concrete ties 2.40 m long and 54.6 kg/m rails, is inadequate for a permanent operation with 80 train pairs daily. Continuous track ...
