The enterprising young Edison.

In 1859, when he was 12, Al gets a job as a trainboy, on the morning train from Port Huron to Detroit, selling newspapers and sweets.

During this period young Edison set up a chemistry lab and a printing press on the train.

The company lent him a carriage where he installed a typewriter and a handmade press.

He was able to write and print four hundred copies a week of "The Grand Trunk Herald", for entertaining the train passengers. 

The money earned with the newspapers was invested on his lab, that was settled in the same train carriage.
