Why the railway tracks are laid on large sleepers?

As we all know that,    P = F/A    so, P  1/A

We also know that rails are heavy vehicles with tons of loads. So, it exerts high pressure on its tracks while traveling and has chances to sink. Hence, to prevent sinking by reducing the pressure exerted by rail, the railway tracks are laid on large sleepers increasing its area.
