Steel sleepers are not preferred much because of their high costs and not resistant to climatic conditions. However, steel sleepers are used by countries where conditions are suitable. Their mass of only 68 kg allows them to be placed easily. However, they cannot fully interact with the ballast layer.
Steel Traverse Positive Aspects;
- Their lifespan is 45-50 years, approximately twice the creosote wooden sleepers.
- It is easier and better stacked in shape and size.
- Frames are lighter and easier to carry.
- It is much easier and perfect to connect and disassemble rails to iron sleepers, it does not slack like in wooden sleepers.
- Also, it does not require anti-fireplace material.
- It is resistant to burning.
- It is resistant to dressing because its ends are with nails.
- It protects well.
Negative Aspects of Steel Crossmember;
- Its light weight is not good in terms of superstructure stability.
- Iron sleeper lines deteriorate faster than wooden sleepers.
- It is not suitable for high speed and heavy load carrying.
- Wooden sleepers are more elastic, stable and comfortable.
- Iron sleepers make noise in the passage of trains, especially if the connections are not tightened well.
- Since iron sleepers pass electrical current, it is difficult to isolate one rail array from another. Therefore, line circuits using rails are not used in electrical signs and automatic blocks.
- Iron sleepers rutubethey do not rust.
- Maintenance is difficult and costly.
- It gives a noisy journey.
