Concrete Sleepers in Railway Tracks
Concrete sleepers are an essential component of railway tracks, and they offer several benefits. The given statements about concrete sleepers are as follows:
1. They improve the track modulus.
2. They have good scrap value.
3. They render transportation easy.
4. They maintain the gauge quite satisfactorily.
Let's discuss each statement in detail:
1. Improving Track Modulus: The track modulus refers to the resistance offered by the track to the loads exerted by the trains. Concrete sleepers are heavy and rigid, which means they can support the tracks better and improve the track modulus. Therefore, statement 1 is correct.
2. Good Scrap Value: Concrete sleepers have a high scrap value, and they are often recycled after their useful life. This is because they are made of reinforced concrete, which is a valuable material in the construction industry. Therefore, statement 2 is correct.
3. Easy Transportation: Concrete sleepers are relatively easy to transport because they are uniform in size and shape. This means that they can be stacked and loaded onto trucks or trains without much difficulty. Therefore, statement 3 is incorrect.
4. Maintaining Gauge: The gauge refers to the distance between the two rails of a railway track. Concrete sleepers can maintain the gauge quite satisfactorily because they are heavy and rigid. This means that they can resist the lateral forces exerted by the trains and prevent the tracks from spreading apart. Therefore, statement 4 is correct.
Conclusion: Therefore, the correct statements about concrete sleepers are 1 and 4.
