In England the cross ties that the track sits on are called "sleepers".
In the United States sleepers are cars that the passengers would spend the night on, also referred to as Pullman cars.

to reduce the pressure exerted by the train
To reduce the pressure exerted by train
this is because sleepers increase the area on which pressure of train is to be exerted.Thus pressure is not concentrated on a single point densely.therefore if there more area there would be less pressure and train will run smoothly
to reduce the pressure exerted by the train
The sleepers - provide a solid surface for the rails to be anchored to. If the tracks were just laid n the ground, they would move every time a train went over them.
To keep the rails at a certain spacing, and to spread the weight of the train over a wider area.
Typically around 0.6m (2 feet) for standard gauge track.
this is because wooden sleepers increase the area on which pressure of train is to be exerted.Thus pressure is not concentrated on a single point densely.therefore if there more area there would be less pressure and train will run smoothly.As we know P=1/A.
To keep the rails at a certain spacing, and to spread the weight of the train over a wider area.
The large surface spreads the weight of the train (and tracks) over a broader area. The shape of the sleepers also helps to keep them firmly in place while trains are running on the tracks.
