Radio comes to the CN Railway

Sandy Stewart, From Coast to Coast,  a Personal Account of Radio in Canada, CBC Enterprises, 1985

 After the formation of the Canadian National Railway as a crown corporation in 1919, the president, Sir Henry Thornton saw the possibilities of radio in promoting travel on the railway. The company set up a chain of radio broadcasting stations across the country and then produced content to fill the airwaves so passengers on the train would be kept entertained all across the country. 

This radio project ended in 1932 for two reasons, the government instituted cost cutting for the railway during the depression and had also decided there should be a national radio system. The stage was set for the formation of the Canadian Broadcasting Corporation, still with us today.
