Sleepers
- Wooden planks laid across railway tracks to hold these tracks in a position are called sleepers.
- Sleepers are an essential component of railway infrastructure as they provide support and stability to the tracks.
- They are typically made of wood, although other materials such as concrete or steel can also be used.
- Sleepers are placed perpendicular to the tracks and are laid on a bed of ballast, which helps distribute the weight of the train evenly and provides a stable foundation.
- The sleepers are spaced at regular intervals along the track, with the distance between them known as the sleeper spacing. This spacing depends on various factors such as the weight and speed of the trains that will run on the track.
- Sleepers play a crucial role in ensuring the safety and smooth operation of trains. They help maintain the alignment and gauge of the tracks, preventing them from spreading apart or deviating from the intended path.
- The wooden sleepers absorb vibrations and shocks caused by the movement of trains, reducing the impact on the tracks and providing a more comfortable ride for passengers.
- Over time, sleepers may deteriorate due to wear and tear or exposure to weather conditions. Regular maintenance and replacement of sleepers are necessary to ensure the safety and efficiency of the railway network.
- In recent years, there has been a shift towards using concrete sleepers instead of wooden ones. Concrete sleepers offer greater durability and longevity, reducing the need for frequent replacements.
- However, wooden sleepers are still widely used, especially in regions where timber is abundant and cost-effective.
- In conclusion, sleepers are essential components of railway tracks that provide support, stability, and safety. They are typically made of wood but can also be made of concrete or steel. Regular maintenance and replacement of sleepers are necessary to ensure the smooth operation of the railway network.
