Rail cars loaded with Canadian wheat travel through the Rocky Mountains on the Canadian Pacific railway line near Banff, Alberta, in an October 6, 2011 file photo. The Canadian government introduced legislation on Wednesday that will allow it to set minimum levels of grain that railways must ship each year to avoid the huge backlogs of grain that have hurt farmers this winter. The Conservative government earlier this month ordered the country's two dominant railroads, Canadian National Railway Co and Canadian Pacific Railway Ltd to double their weekly grain volumes to 1 million tonnes combined over a four-week period to clear the massive crop logjam.
