I watched the last half of a movie titled 49th Parallel
on Turner Classic Movies yesterday. Released in 1941, prior to the United States' involvement in World War II, the story is about a German U-boat that is sunk in Canada's Hudson Bay. A small band of survivors from the U-boat make their way to shore and most of the movie is about their attempts to remain undercover while trying to make their way back to Germany.
The suvivors keep being exposed and captured or killed until only the U-boat's captain remains. The final portion of the movie has the captain hiding in the baggage car of a Canadian National passenger train bound for Niagara Falls, Ontario. When the train arrives in Niagara Falls, the passenger cars are cut off from the train with the baggage car, pulled by a CN 4-6-2, destined to go across the Niagara River to Niagara Falls, NY where the captain hopes to get off the train in the then officially neutral US, where he plans to make his way to the German consulate and eventually back to Germany.
However his plans are thwarted when a Canadian Army deserter who joined the army to fight the Germans, not stand guard duty at a Canadian base, also makes his way into the baggage car.
Great black and white scenes of the train as it pulls into Niagara Falls, Ontario, where Canadian customs officials enter the baggage car, inspect the contents (With both the German and the Canadian in hiding.) and close and lock a gate preventing access to the contents. The stowaways have a confrontation while the locomotive and baggage car cross the international bridge and when the American customs officials enter the baggage car and discover the pair, they send the train back to the Canadian side, informing Canadian customs via telephone that there are two undeclared items in the car.
The movie closes with scenes of the train backing to Canada across the same international bridge with the implication that in the baggage car the Canadian Army deserter is finally getting his opportunity to fight the Germans.

Ah, good ol' Youtube! I found this clip, showing a Canadian Pacific passenger train in the Canadian Rockies and the final scenes I detailed above in this clip, approximately 15 minutes long:
