Caption: CN 131 (full ID: Q13132-22) is nearly finished its run as it enters the Port of Montreal with CN 3019, CN 3182 & BCOL 4642 for power. Due to a blockade on CN's Kingston Sub, this train has taken a very lengthy detour, going north out of Toronto on CN and the Ontario Northland, getting back to CN rails at Noranda and then heading back south via the CN Val D'Or, St-Maurice, Lac St-Jean, La Tuque, Joliette and St-Laurent Subs.
