In a small midwestern town there lived a retired railroad engineer named William Johnson.The main line on which he had worked for so many years passed through the town.Mr.Johnson suffered from insomnia and would often wake up at any odd hour of the night and be unable to fall asleep again.He found it helpful,in such cases,to take a walk along the deserted streets of the town,and his way always led him to the railroad crossing.He would stand there thoughtfully watching the track until a train thundered by through the dead of the night.The sight always cheered the old railroad man,and he would walk back home with a good chance of falling asleep
