Question
Why are railway tracks laid on large-sized concrete sleepers? Explain.
✓

Answer

When the train passes over a railway track, the whole weight of the train acts on the railway line beneath it. Due to large sized concrete sleepers, the force of this weight spreads out over a large area, thereby reducing the pressure on the ground. As a result, the railway track can bear it.
