Mount Macdonald Tunnel
The Mount Macdonald Tunnel is in southeastern British Columbia, on the Revelstoke–Donald segment. This single-track tunnel, which carries the Canadian Pacific Railway (CP) main line under Mount Macdonald in the Selkirk Mountains, handles most westbound traffic, whereas the Connaught Tunnel handles mostly eastbound. Shortcomings of the Connaught Track By the 1970s, it was evident that the Connaught Tunnel alone could not meet the increasing traffic demands. The major growth opportunities were primarily in the bulk commodities of coal, sulfur, and potash. In 1980, the estimated construction cost of $300 million was almost 20 per cent of CP's gross income for 1979. Furthermore, westbound grain transportation had been an ongoing liability for the railways. Consequently, CP was unwilling to proceed with a new tunnel unless the Crow Rate, which did not cover the variable cost of grain movement, was addressed. In response, the federal government gradually increased this rate from 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Pacific Railway
The Canadian Pacific Railway (french: Chemin de fer Canadien Pacifique) , also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), is a Canadian Class I railway incorporated in 1881. The railway is owned by Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001. Headquartered in Calgary, Alberta, the railway owns approximately of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also serves Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States. The railway was first built between eastern Canada and British Columbia between 1881 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a commitment extended to British Columbia when it entered Confederation in 1871; the CPR was Canada's first transcontinental railw ...

Crowsnest Pass
Crowsnest Pass (sometimes referred to as Crow's Nest Pass, french: link=no, col du Nid-de-Corbeau) is a low mountain pass across the Continental Divide of the Canadian Rockies on the Alberta–British Columbia border. Geography The pass is located in southeast British Columbia and southwest Alberta, and is the southernmost rail and highway route through the Canadian Rockies. It is the lowest-elevation mountain pass in Canada south of the Yellowhead Pass (); the other major passes, which are higher, being Kicking Horse Pass (), Howse Pass () and Vermilion Pass (). Crowsnest Pass comprises a valley running east–west through Crowsnest Ridge. On the Alberta side, the Crowsnest River flows east from Crowsnest Lake, eventually draining into the Oldman River and ultimately reaching Hudson Bay via the Nelson River. Summit Lake on the British Columbia side drains via three intermediary creeks into the Elk River, which feeds into the Kootenay River, and finally into the Columbia ...

Simplon Tunnel
The Simplon Tunnel (''Simplontunnel'', ''Traforo del Sempione'' or ''Galleria del Sempione'') is a railway tunnel on the Simplon railway that connects Brig, Switzerland and Domodossola, Italy, through the Alps, providing a shortcut under the Simplon Pass route. It is straight except for short curves at either end. It consists of two single-track tunnels built nearly 15 years apart. The first to be opened is long; the second is long, making it the List of longest tunnels, longest railway tunnel in the world for most of the twentieth century, from 1906 until 1982, when the Daishimizu Tunnel opened. Culminating at a height of only above sea level, the Simplon Tunnel was also the lowest direct Alpine crossing for 110 years, until the opening of the Gotthard Base Tunnel in 2016. The tunnel has a maximum rock overlay of approximately , also a world record at the time. Temperatures up to have been measured inside the tunnel.

Daishimizu Tunnel
The is a railway tunnel on the Jōetsu Shinkansen on the border of Gunma Prefecture and Niigata Prefecture, Japan. In 1978, the Dai-Shimizu tunnel was completed. This tunnel was dug for the Jōetsu Shinkansen that was to be completed in 1982. This tunnel was the world's longest railway tunnel at until the Seikan Tunnel was built. During the construction, a fire created a large amount of smoke in the tunnel, and 16 workers died from carbon monoxide poisoning. When this tunnel was completed, the travel time between Niigata and Tokyo went down to approximately one hour and forty minutes, three hours faster than using the Jōetsu Line The is a major railway line in Japan, owned by the East Japan Railway Company (JR East). It connects Takasaki Station in Gunma Prefecture with Miyauchi Station in Niigata Prefecture, linking the northwestern Kanto region and the Sea of Japan c ....

Seikan Tunnel
The Seikan Tunnel ( ja, 青函トンネル, or , ), is a dual-gauge railway tunnel in Japan, with a portion under the seabed of the Tsugaru Strait, which separates Aomori Prefecture on the main Japanese island of Honshu from the northern island of Hokkaido. The track level is about below the seabed and below sea level. The tunnel is part of the standard-gauge Hokkaido Shinkansen and the narrow-gauge Kaikyō Line of the Hokkaido Railway Company (JR Hokkaido)'s Tsugaru-Kaikyō Line. The name ''Seikan'' comes from combining the ''on'yomi'' readings of the first characters of , the nearest major city on the Honshu side of the strait, and , the nearest major city on the Hokkaido side. The Seikan Tunnel is the world's longest undersea tunnel by overall length (the Channel Tunnel, while shorter, has a longer undersea segment). It is also the second-deepest transport tunnel below the sea level after the Ryfylke Tunnel, a road tunnel in Norway which opened in 2019, and the second ...

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drilling And Blasting
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite. Before the advent of tunnel boring machines (TBMs), drilling and ...
