In accordance with the load transfer model in railways; The footings laid at regular intervals perpendicular to the rails, which transfer the forces transferred by the rail to itself over a wider surface to the ballast layer, determine and protect the road clearance and keep the road on the axis of the road against side effects, are called sleepers. The first sleeper type used in railways are wooden sleepers. This type of traverse found in nature is especially used in railway switches. The positive and negative features of the preferred wooden sleeper due to its flexibility and insulation are as follows:
Features of Wooden Traverse
- Due to the flexibility in the natural structure of the wood, it prevents the impact effect as it flexes the forces coming from the rail and it does not damage the ballast since its friction is also low.
- Maintenance costs are low.
- It is flexible.
- It is heavy enough not to disturb road stabilization and light enough to be transported.
- It provides a noiseless journey.
- It is insulating.
- It is highly affected by humidity.
- It is likely to burn.
- It is resistant to dressing, the road usually slides out on the curves.
- It is difficult to maintain blister.
- Their lifespan is short.
