`` Young Edison read all he could find about electricity . That always fascinated him . But the father seemed to have a hard time making a living and Al , as they called the boy , went to work . He began selling newspapers in Port Huron , but there was not much in that , so he got a chance to sell on the seven o'clock train for Detroit .

The train was a local with only three cars -- baggage , smoking and passenger .
