Concrete railway sleepers
Railway sleepers are used as a base for rail road tracks and to hold the rails to the correct gauge. Their design and weight, with a large soffit area ensures maximum contact with ballast, and reduces pressure on the ballast thereby ensuring excellent rail track stability. Concrete sleepers maintain their integrity in all weather conditions, ensuring rail seat inclinations and rail gauge. The sleepers have become more commonly used because they offer better economy and support to the rails under high speed and heavy traffic than wooden sleepers.
Concrete railway sleeper design and manufacture
Kwena’s concrete railway sleepers are manufactured to a minimum strength and weight of 215kg. The sleepers are designed to attain minimum cube compression strength of 60MPA after 28 days. This enables the sleeper to stand up to different loads.
The on-site laboratory ensures that all materials are tested before use, and that the sleeper dimensions and requirements are met. One sleeper out of every total sleeper production per shift is selected at random and then tested as per laid down specifications. KCP is currently expanding its sleeper production capacity to meet the anticipated increased demand.
The benefits of concrete sleepers:
- Easy to install
- Extra weight makes track more stable, particularly with changes in temperature
- Do not expand under hot conditions unlike wooden sleepers
- Withstand fire hazards better than wooden sleepers
- Less maintenance means lower ongoing costs and less track closures
- Replaces timber sleepers which are very scarce and expensive
- More durable than timber sleepers
- Made from sustainable materials / environmentally friendly
