Everyone loves crossing railway track but walking on those crushed stones is not a cakewalk. While it is clearly said that crossing tracks is highly dangerous, 1 out of 200 people trying to do that loses its life while crossing tracks in India. I’m sure you might have also crossed railway tracks at least once in your life.
Coming back to the point, have you ever questioned the reason behind those pebbles?
These wooden sleepers help to keep a firm hold of the tracks.
But these stones are not smooth, they have sharp edges so that the wooden beams don’t slide over each other.
