Formation of the Canadian National Railways subsidiary

On May 31, 1925, Canadian National Railways completed key reorganizations integrating former Grand Trunk Pacific assets into a unified transcontinental system. This followed the 1919 nationalization wave, with Sir Henry Thornton leading efforts to modernize motive power and standardize operations across vast distances. The move helped stabilize Canadian rail freight amid economic recovery and competition from emerging highways, fostering national unity through reliable passenger and goods transport.
