Wooden sleepers in Railway Tracks plays a major role. It is the best. And it satisfies all the needs of a sleeper.  In the Railway bridges, the railway rail tracks are of timber sleepers. It is because of its less weight, high load carrying capacity and its ability to absorb shocks and vibrations. The lifetime of wooden sleepers depends upon the ability to resist all chemical, physical and mechanical deformations.

Wooden sleepers

The chemical deformations are damages because of the chemical attacks in woods, like efflorescences.

Wooden sleepers

The physical deformations are because of the insect attacks like termites, white ants, decay, etc.

wooden Sleepers are the old traditional material used in the construction of railway track sleepers. It satisfies all needs of a good sleeper. The life of wooden sleepers depends on many facts like wear and tear, decay, and attack by termites, etc. And because of a high scarcity of wooden sleepers, it is replacing with the metal and concrete sleepers.
