Rail sleepers with steel rails commonly use timber and concrete as materials. Timber sleepers, also known as wooden sleepers, have been extensively used in railway construction for many years. They are typically crafted from hardwood, such as oak or jarrah, which ensures durability and resistance against decay. Timber sleepers possess the advantages of being lightweight, easy to handle, and possessing good elasticity, which aids in absorbing the vibrations and shocks generated by passing trains. Moreover, they are relatively cost-effective in comparison to alternative materials.
On the contrary, concrete sleepers have gained popularity in recent times due to their heightened durability and longevity. They are manufactured by pouring concrete into a reinforced mold containing steel bars. Concrete sleepers provide exceptional stability, strength, and resistance against wear and tear. They are capable of withstanding heavy loads and are less prone to rot or decay when compared to timber sleepers. However, the manufacturing and installation of concrete sleepers are more laborious and expensive, primarily due to their weight.
The selection of either timber or concrete sleepers depends on various factors, including specific railway requirements, budgetary constraints, and environmental considerations. Both materials possess their own set of advantages and disadvantages.
The common materials used for rail sleepers with steel rails are timber and concrete.
