Description
When British Columbia joined what is now Canada in 1871, there was a need for a railway to link the province to the rest of the country. The problem was the high Rocky Mountains! Even though it was still high and steep, Kicking Horse Pass was the best option. Initially, the grade was very steep and downhill derailments were a problem, as well as pushing the uphill loads. The solution for a more gradual grade came from one of the railway's Assistant Chief Engineers. He modeled the Spiral Tunnels after a system used in Switzerland whereby there were two large loops along the path up to the pass. This is a view of the Upper Spiral Tunnel located in Cathedral Mountain. It is 3255 feet long with a curvature of 288 degrees. The difference in elevation between upper and lower portal is 48 feet. It's difficult to see the large train against the much MUCH larger mountain, which only emphasizes the magnitude of the problem! Despite the great improvement, nature still reigns supreme and rockfalls, mudslides and avalanches are some of the challenges still faced today. The Canadian Rocky Mountain Parks of Banff, Jasper, Kootenay and Yoho along with three provincial parks comprise a UNESCO World Heritage site.
