"Silver Streak" was filmed in the 1970s, and no US railroads wanted to be involved with the production, so filming was moved to Canada using CP Rail F units and a streamlined consist--similar to wthat the "Canadian" was using at that time. As you watch the film, you will see many highlights of scenes along CP's right of way through the Rockies, plains, and other points of interest. I have taken to watching the movie more for the train than for the plot.
