High Quality Concrete Railway Sleepers 

A railroad tie/railway tie/cross-tie (North America), or railway sleeper (UK and Australasia) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and sub-grade, hold the rails upright and keep them spaced to the correct gauge.


 

 

 

 

 

 

Task of sleepers:

Supporting of rail
Distributing of loads
Keeping the gauge


Track structures according to the type of support:
1.Cross-ties
2.Combination of cross-ties and mono-blocks
3.Mono-blocks
4.Longitudinal beam
5.Slab track

Railway sleeper were traditionally made of wood,but pre-stressed concrete, steel are now widely used.

Material

Advantages

Disadvantages

Wooden Sleepers

Good electric isolation

Easy work ability

Flexibility

Less sensitivity to derailments

Special treatment is necessary to 

       obtain maximum life span

Max. Life span is 35 years

Concrete Sleepers

The track is more stable

Increased lateral resistance

Excellent gauge keeping

Long life span appr. 60 years

Surface is canted

Derailment can cause irreparable 

      damages

Steel Sleepers

Long life

Very good longitudinal and lateral resistance 

       in the ballast 

Special “Y” shape with extra lateral resistance

Less weight and that’s why less 

       stability to track

Preforming of the ballast bed because 

       of the hollow shape
