Promotional photo showing the Canadian Pacific Railway's Atlantic Express passenger train climbing the Rocky Mountains in 1890. The image of three hard-working steam locomotives emphasized railroad technology's ability to overcome natural obstacles, inspiring confidence in potential passengers. The train was running on a very steep temporary route up Kicking Horse Canyon, completed in 1884 on a 4.5% grade. The compromising route was necessary in the timely construction of Canada's first transcontinental railroad, but was ultimately replaced in 1909 with the completion of CPR's famous Spiral Tunnels, which reduced the grade to 2.2%, which is still steep but far more manageable. Steeply graded temporary routes were common throughout the western mountains of North America.
