You can get a ballpark idea with a little calculation: 5 million tons per year works out to an average of 13,500 tons a day. A typical freight train is a little over one ton per foot. Therefore, you would need about 13,000 feet of train per day to trip the threshold. The through routes on the northern prairies would qualify, but not the Campbellton line, nor the line north of Thompson to Churchill.
