It was designed for carrying bundled building supplies such as dimensional lumber, wallboard and fence posts. Both sides must be loaded symmetrically to avoid tipping over. Canadian National is the largest railway in Canada, in terms of both revenue and the physical size of its rail network; It’s currently Canada’s only transcontinental railway company, spanning Canada from the Atlantic Coast in Nova Scotia to the Pacific Coast in British Columbia.
