Question

why wide wooden sleepers are kept below railway lines

Answer 1

To increase the area at which the whole pressure of the train will fall...
This will prevent the train from sanking into the ground..

Answer 2

Hi

Here devil1407

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.

To avoid this wooden and concerte sleepers had been laid in the railway tracks.

Hope it helps u

Thanx..Bye
