Detailed explanation-1: -Railway Sleepers are wooden planks laid across railway tracks; they hold the tracks in position . Between 1, 760 and 2, 000 sleepers are needed to lay 1 mile of railway track .
Detailed explanation-2: -Wooden or concrete sleepers are kept below the railway line to increase the area of contact of the train. As a result, there is less pressure of the train on the ground preventing it from sinking.
Detailed explanation-3: -CBSE, JEE, NEET, CUET. = 470 trees.
Detailed explanation-4: -So, we can say, Railway tracks are laid on large sized wooden sleepers so that the thrust due to the weight of the train is spread over a large area . This reduces the pressure on the ground which would prevent the yielding of the ground.
