The Spiral Tunnel is a famous railway tunnel in the Canadian Western Pacific Railway that passes through the Rocky Mountains. Because this section of the mountain height leads to too much drop, the tunnel is rotated around the mountain to reduce the slope, (similar to China’s Juyongguan Zhan Tianyou" "The role of the road), you can see that the locomotive is in the upper cave and the rear of the car is in the lower cave. The 8-shaped Spiral Tunnel is one of the most critical sections of the Canadian Pacific Railway's vast project construction. It is also saturated with the blood and sweat of countless Chinese railway workers. Nowadays, trains still pass through the tunnel regularly every day, and many tourists stop and watch.
Canadian Pacific Railway's eight-shaped spiral tunnel/8-shaped spiral tunnel (Spiral Tunnel) is the easternmost part of Yoho National Park, close to a small scenic spot in Banff National Park that is easily overlooked. The viewing point is right here On the left hand side of Highway 1, if you are a train enthusiast, this attraction must not be missed! The beautiful and prosperous province of British Columbia (British Columbia) until the mid to late 19th century was still nothing more than a newly developed territory of the Hudson’s Bay Company (similar to the colonial company of the East India Company). The United States, which is rapidly expanding westward, has no advantage. The extension of the Canadian railway system to this place has become a major national security project. Railway construction in the steam engine age was dangerous and slow, especially through the steep and unstable Rocky Mountains (Banff, Yoho and Glacier National Parks today). The spiral tunnel is one of the most dangerous sections of the Canadian Pacific Railway's vast project construction. Countless Chinese workers are used as consumables to fight for their lives here, and finally pass through the uninhabited Kicking Horse Pass, which will be the easternmost part of BC The town of Golden/Golden/Golden (Golden, in many translations) on the front side is connected with Lake Louise in the Bow River Valley in the westernmost part of Alberta. Since then, BC has been technically incorporated into the Canadian Federation. With reference to the "herringbone track" of China's Beijing-Zhangjiakou Railway, we can know that once a railway in the steam engine era passes a certain degree, a locomotive cannot be towed. The slope of this section was once too large and four steam locomotives were needed to tow it, which was extremely dangerous. In August 1909, the railway company finally opened a figure-eight winding railway tunnel in Mount Ogden and Cathedral Mountain, increasing the railway track by 6.4 kilometers, reducing the slope of the spiraling mountain to 2.2%. This relieved the nightmare of Dashangang. The running speed of the train has been greatly increased from the previous speed of 8 kilometers per hour to 40 kilometers, and the tractor head has also been reduced from 4 to 2. If tourists come and go in a hurry, they can only see an empty tunnel entrance which is meaningless, but if they are willing to spend some time waiting, when the train passes through the observation point of the 8-shaped Panshan Tunnel, they will see that the train has three sections at the same time. The scene is quite magnificent as it winds its way through the staggered tunnels and belt-like railroad tracks.
