Shinkansen
From Wikipedia, the free encyclopedia
The Shinkansen (新幹線?) is a network of high-speed railway lines in Japan operated by four Japan Railways Group companies. Since the initial Tōkaidō Shinkansen opened in 1964 running at 210 km/h (130 mph), the network (2,459 km or 1,528 miles) has expanded to link most major cities on the islands of Honshū and Kyūshū with running speeds of up to 300 km/h (188 mph), in an earthquake and typhoon prone environment. Test run speeds have been 443 km/h (275 mph) for conventional rail in 1996, and up to a world record of 581 km/h (361 mph) for maglev trainsets, in 2003.
Shinkansen literally means "New Trunk Line", referring to the tracks, but the name is widely used in and outside Japan to refer to the trains running on the lines as well as the system as a whole. The name "Superexpress" (超特急 chō-tokkyū?), initially used for Hikari trains, was officially retired in 1972 but is still used in English-language announcements and signage.
In contrast to older lines, Shinkansen are standard gauge, and use tunnels and viaducts to go through and over obstacles, rather than around them. It is separated from conventional rail and constructed in completely renewed railway system, using ATC (Automatic train control system without signal), minimum 4,000 meters (2,500 meters in the oldest Tokaido Shinkansen) radius curve, elevated track without crossing, and so forth.
Namely Tokaido Shinkansen is the world busiest high-speed rail and carries 375,000 passengers a day. Though largely a long-distance transport system, the Shinkansen also serves a few regular commuters who travel to work into metropolitan areas from cities beyond the metropolitan areas.

[edit] History
Japan was the first country to build dedicated railway lines for high speed travel. Because of the mountainous terrain, the existing network consisted of 3 ft 6 in (1,067 mm) narrow gauge lines, which generally took indirect routes and could not be adapted to higher speeds. Consequently, Japan had a greater need for new high speed lines than countries where the existing standard gauge or broad gauge rail system had more upgrade potential.
[edit] Early proposals
The popular English name bullet train is a literal translation of the Japanese term dangan ressha (弾丸列車), a nickname given to the project while it was initially being discussed in the 1930s. The name stuck due to the Shinkansen locomotive's resemblance to a bullet and its high speed.
The "Shinkansen" name was first formally used in 1940 for a proposed standard gauge passenger/freight line between Tokyo and Shimonoseki, using steam and electric locomotives with a top speed of 200 km/h (124 mph). Over the next three years, the Ministry of Railways drew up more ambitious plans to extend the line to Beijing (through a tunnel to Korea) and even Singapore, and build connections to the Trans-Siberian Railway and other trunk lines in Asia. These plans were abandoned in 1943, as Japan's position in World War II worsened. However, some construction did commence on the line; several tunnels on the present-day Shinkansen date to the war-era project.
In 1957, Odakyu Electric Railway introduced its Romancecar 3000 SE service, setting a world speed record of (145 km/h or 90 mph) for a narrow gauge train. This train gave designers the confidence they could build an even faster standard gauge train, as the first Shinkansen, the 0 Series, and built on the success of the Romancecar.
[edit] Construction
Following the end of World War II, high speed rail was forgotten for several years. Passengers of conventional Tokaido Line increased and by the mid-1950s, the Tōkaidō Main Line was operating at full capacity, and the Ministry of Railways decided to revisit the Shinkansen project. Government approval came in 1958, and construction of the first segment of the Tōkaidō Shinkansen between Tokyo and Osaka started in 1959. Some of the construction was financed by a US$80 million loan from the World Bank. A testing facility for rolling stock, now part of the line, opened in Odawara in 1962.
The Tōkaidō Shinkansen opened on October 1, 1964, in time for the Tokyo Olympics. Conventional Limited express ran from Tokyo to Osaka in 6h40, but Shinkansen ran in only 4h00, and in 1965 shortened to 3h10. It was an immediate success, reaching the 100 million passenger mark in less than three years on July 13, 1967 and one billion passengers in 1976. Sixteen-car trains were introduced for Expo '70 in Osaka.
The first Shinkansen trains ran at speeds of up to 210 km/h (130 mph)[1], later increased to 220 km/h (135 mph). Some of these trains, with their classic bullet-nosed appearance, are still in use, and a driving car from one of them is now in the British National Railway Museum in York.
[edit] Network expansion
This early success prompted an extension of the first line westward to Hiroshima and Fukuoka (the Sanyo Shinkansen), and was completed in 1975.
Prime Minister Kakuei Tanaka was an ardent supporter, and his government proposed an extensive network paralleling most existing trunk lines. Two new lines, the Tohoku Shinkansen and Joetsu Shinkansen, were built following this plan. Many other planned lines were delayed or scrapped entirely as the national railway went further into debt, largely due to the high costs of building the Shinkansen network. By the early 1980s, Japan National Railways was practically insolvent, leading to privatization in 1987.
Despite this, development of the Shinkansen continued. Several new models of train followed the first, generally each with its own distinctive appearance. Shinkansen trains now run regularly at speeds of up to 300 km/h (186 mph), putting them among the fastest trains running in the world, along with the French TGV, Italian TAV, Spanish AVE, and German ICE trains.
Since 1970, development has also been underway for the Chūō Shinkansen, a maglev train planned to run from Tokyo to Osaka. On December 2, 2003, the 3-car maglev trainset JR-Maglev MLX01 reached a world speed record of 581 km/h (361 mph).
In 2003, JR Central reported that the Shinkansen's average arrival time was within six seconds of the scheduled time. This includes all natural and human accidents and errors and is calculated from all of about 160,000 Shinkansen trips made. The previous record was from 1997 and was 18 seconds. Japan celebrated 40 years of high speed rail in 2004, with the Tōkaidō Shinkansen line alone having carried 4.16 billion passengers. According to Japanrail.com, the website for companies that operate Shinkansen, the network has carried over 6 billion passengers.
[edit] Safety record
During the Shinkansen's 40-year, 6 billion passenger history, there have been no passenger fatalities due to derailments or collisions (including earthquakes and typhoons). Injuries and a single fatality have been caused by doors closing on passengers or their belongings; attendants are employed at platforms to prevent this. There have, however, been suicides by passengers jumping both from and in front of moving trains.
The only derailment of a Shinkansen train in passenger service occurred during the Chūetsu Earthquake on October 23, 2004. Eight of ten cars of the Toki No. 325 train on the Jōetsu Shinkansen derailed near Nagaoka Station in Nagaoka, Niigata. There were no casualties among the 154 passengers. [2]PDF (43.8 KiB) In the event of an earthquake, an earthquake detection system can bring the train to a stop very quickly. Experimental Fastech 360 trains have ear-like air resistance braking flaps to assist emergency stops at high speeds.
[edit] Future
Noise pollution concerns mean that increasing speed is becoming more difficult. Current research is primarily aimed at reducing operational noise, particularly the "tunnel boom" phenomenon caused when trains exit tunnels at high speed.
JR East has announced that new trains capable of up to 320 km/h (199 mph) are to be introduced coinciding with the opening of the Tohoku Shinkansen extension from Hachinohe to Shin-Aomori in early 2011. Extensive trials using the Fastech 360 test trains has shown that operation at 360 km/h is not currently feasible due to problems of noise pollution, overhead wire wear, and braking distances. This may indicate the limits to railed Shinkansen technology, and eventually maglev or another technology will need to replace it. Operation at speeds of up to 320 km/h between Utsunomiya and Shin-Aomori is expected to allow journey times of around 3 hours for trains from Tokyo to Shin-Aomori (a distance of approximately 675 km or 419 miles).
The Kyūshū Shinkansen from Kagoshima to Yatsushiro opened in March 2004. Three more extensions are planned for opening by 2010: Hakata-Yatsushiro, Hachinohe-Aomori, and by 2014: Nagano-Kanazawa, and 2015: Aomori-Hakodate (through the Seikan Tunnel). There are also long-term plans to extend the network, Hokkaidō Shinkansen from Hakodate to Sapporo, Kyūshū Shinkansen to Nagasaki, as well as to complete a link from Kanazawa back to Osaka, although none of these are likely to be completed by 2020. Also, the CEO of JR Central announced plans to have the maglev Chuo Shinkansen operating Tokyo-Nagoya in 1 hr (366 km/227 miles) by 2025.
The Narita Shinkansen project to connect Tokyo to Narita International Airport, initiated in the 1970s but halted in 1983 after landowner protests, has been officially cancelled and removed from the Basic Plan governing Shinkansen construction. Parts of its planned right-of-way will be utilized by the Narita Rapid Railway link when it opens in 2010. Although the NRR will use standard-gauge track, it will not be built to Shinkansen specifications and it would not be feasible to convert it into a full Shinkansen line.
[edit] List of Shinkansen lines
The main Shinkansen lines are:
- Tōkaidō Shinkansen (Tokyo – Shin-Osaka)
- Sanyō Shinkansen (Shin-Osaka – Hakata)
- Tōhoku Shinkansen (Tokyo – Hachinohe)
- Jōetsu Shinkansen (Ōmiya – Niigata)
- Hokuriku Shinkansen or Nagano Shinkansen (Takasaki – Nagano)
- Kyūshū Shinkansen (Shin-Yatsushiro – Kagoshima-Chūō)
Two further lines, known as Mini-Shinkansen (ミニ新幹線), have also been constructed by upgrading existing sections of line:
There are two standard gauge not technically classified as Shinkansen lines but with Shinkansen services:
- Hakata Minami Line (Hakata – Hakata-Minami)
- Gala-Yuzawa Line – technically a branch of the Jōetsu Line – (Echigo-Yuzawa – Gala-Yuzawa)
[edit] Future lines
Many Shinkansen lines were proposed during the boom of the early 1970s but have yet to be constructed. These are called Seibi Shinkansen (整備新幹線) or "planned Shinkansen." One of these lines, the Narita Shinkansen to Narita Airport, has been officially cancelled, but a few remain under development.
- Tōhoku Shinkansen extension from Hachinohe Station to Shin-Aomori is under construction and will open by 2010.
- Hokuriku Shinkansen extension to Kanazawa is under construction and will open by 2014. The complete extension of the line to Osaka is under development, and only Fukui Station is under construction.
- Kyūshū Shinkansen extension to Hakata is under construction and will open by 2010.
- The second Kyūshū Shinkansen route from Shin-Tosu to Nagasaki section is under development.
- The Hokkaidō Shinkansen from Shin-Aomori to Shin-Hakodate is under construction and will open by 2015. A further extension of the line from Shin-Hakodate to Sapporo is under development.
[edit] Shinkansen technology outside Japan
Railways using Shinkansen technology are not limited to those in Japan.
- Taiwan High Speed Rail operates 700T Series sets built by Kawasaki Heavy Industries.
- China has ordered 60 eight-car 200 km/h (124 mph)EMUs based on the E2-1000 Series design named CRH-2 built by a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric Corporation, and Hitachi, for deliveries starting in March 2006.
- Class 395 EMUs were built by Hitachi based on Shinkansen technology for use on high-speed commuter services in Britain on the High Speed 1 line.
- Japan is currently promoting its shinkansen technology to the Brazilian Government for use on the planned high speed rail link system set to crisscross Brazil.[citation needed]
[edit] List of Shinkansen train models
Trains can be up to sixteen cars long. With each car measuring 25 m (82 ft) in length, the longest trains are 400 m (1/4 mile) from front to back. Stations are similarly long to accommodate these trains. Japan's maglev trains are considered Shinkansen.

[edit] List of types of Shinkansen services
Originally intended to carry passenger and freight trains by day and night, the Shinkansen lines carry only passenger trains. The system shuts down between midnight and 06:00 every day for maintenance. The few overnight trains that still run in Japan run on the old narrow gauge network that the Shinkansen parallels.
