The History of Railway Sleepers

Railway sleepers, also called railroad ties, railway ties or crossties, are an important railway component. Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of gauge.

Having been developed for more than one hundred years, the railway ties need to meet the different requirements of the various railway tracks. In the past time, railroad ties were usually made of wood and had continued for about 50 years.

Then with the development of steel tracks, steel sleepers appeared. And later, the first concrete sleeper experiment was made in Germany in 1906 between the line Nuremberg and Bamberg.

In the recent time, concrete sleepers are widely used, especially in Europe and Asia. And in UK, steel ties are common. Besides, plastic composite ties are also employed in the rail track transportation.

Historically, wooden ties were made of a variety of softwood and some popular hardwoods such as oak, jarrah, and karri. They are only suitable for low-speed lines with a speed limit of 160 km/h. As to acceptable species of wood for sleepers, the types are European oak, beech, pine etc. But nowadays, wooden sleepers are mostly replaced by concrete sleepers in some countries.

What is a Railway Sleeper?

Railway sleepers are the components on which the rails are arranged with proper gauge. These sleepers generally rests on ballast and is also called as ties in some regions. The load from rails when train passes, is taken by these sleepers and is distributed it to the ballast.

Functions of Railway Sleepers

The basic functions of Railway sleepers are to:

hold the rails strongly and to maintain uniform gauge.

transfer the load from rails to the ballast or ground.

reduce the vibrations coming from rails.

offer longitudinal and lateral stability.

Classification of Railway Sleepers

1.Based on the materials used, railway sleepers are classified into following types.

2.Wooden sleepers

3.Concrete sleepers

4.Steel sleepers

5.Cast iron sleepers

6.Composite sleepers

A plastic sleeper is a kind of railway sleeper made from mixed plastics as the main material. Railway sleeper (railroad ties or crosstie in the US) is a component laying under the track to support railroad rails and transfer the pressure to the ballast. There are mainly four types of railway sleepers according to the materials. Wooden sleeper, concrete sleeper, steel sleeper, and plastic sleeper. They differ in many aspects and are suitable for different construction conditions. As a new material, the plastic sleeper is a good alternative to wooden and concrete sleepers.

Technical Specifications of BS-500 Series Steel Sleepers:

A railroad tie/railway tie/crosstie or railway sleeper is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge.
