Question

Why railway tracks are laid on large size wooden sleepers

Answer 1

Trains have huge masses and rails are narrow. Therefore if they are directly put on earth, they will sink down due to the extreme pressure it would exert on earth when run over by the train.

Answer 2

Answer:

Railway tracks are laid on large sized wooden sleepers so that the thrust due to the weight of train is spread over large area . This reduces the pressure on the ground which would prevent the yielding of the ground.
