Question

Explain why, wooden (or concrete) sleepers are kept below the railway line.

Solution

Wooden or concrete sleepers are kept below the railway line because the weight of the train is spread over a large area of the sleepers. Therefore, the pressure acting on the ground under the sleepers is reduced. This prevents the shrinking of the ground under the weight of the train.

  Is there an error in this question or solution?
