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).

Jōetsu Shinkansen
The is a high-speed shinkansen railway line connecting Tokyo and Niigata, Japan, via the Tōhoku Shinkansen, operated by the East Japan Railway Company (JR East). Despite its name, the line does not pass through the city of Jōetsu or the historical Jōetsu region, which instead are served by the Hokuriku Shinkansen. The name instead originates from the parallel Jōetsu Line, which in turn is named after the two provinces that it connects: Jōshū (an alternate name for Kōzuke Province which comprises today's Gunma Prefecture), and Echigo Province (modern day Niigata Prefecture). Train services * '' Toki'', Tokyo – Niigata (limited-stop/ mostly all-stations since 30 December 2002) (Although it was first introduced as an all-stations service from 1982 to 1997) * '' Tanigawa'', Tokyo – Echigo-Yuzawa/ Gala-Yuzawa (Seasonal) (all-stations / mostly all-stations since 1 October 1997) Discontinued services * '' Asahi'', Tokyo – Niigata (discontinued 30 November 2002) ...

Carbon Monoxide Poisoning
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as " flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. The classically described "cherry red skin" rarely occurs. Long-term complications may include chronic fatigue, trouble with memory, and movement problems. CO is a colorless and odorless gas which is initially non-irritating. It is produced during incomplete burning of organic matter. This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (symbol COHb or HbCO) preventing the blood from carrying oxygen and expelling carbon dioxide as carbaminohemoglobin. Additionally, many other hemoproteins such as myoglob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spring Water
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. A spring produced by the emergence of geothermally heated groundwater is known as a hot spring. The yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depresses sharply. Springs may also be formed as a result of karst topography, aquifers or volcanic activity. Springs have also been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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.

Railway Tunnels In Japan
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th c ...

Tunnels Completed In 1982
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two Portal (architecture), portals common at each end, though there may be access and ventilation openings at various points along the length. A Pipeline transport, pipeline differs significantly from 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 transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), 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 passa ...
