For the record label, see Shinkansen Records. The Shinkansen (新幹線) also known as "the bullet train" is a network of high-speed railway lines in Japan operated by four Japan Railways Group companies. Starting with the 210 km/h (130 mph) Tōkaidō Shinkansen in 1964, the now 2,459 km (1,528 mi) long network has expanded to link most major cities on the islands of Honshū and Kyūshū at speeds up to 300 km/h (186 mph). Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to a world-record 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 inside and outside Japan to refer to the trains as well as the system as a whole. The name "Superexpress" (超特急 chō-tokkyū), initially used for Hikari trains, was retired in 1972 but is still used in English-language announcements and signage. The Tōkaidō Shinkansen is the world's busiest high-speed rail line. Carrying 151 million passengers a year (March, 2008),[1] it has transported more passengers (over 6 billion)[2] than any other high speed line in the world.[3] Between Tokyo and Osaka, the two largest metropolises in Japan, ten trains per hour with 16 cars each (1,300 seats capacity) run in each direction with minimum 3 minutes frequency. Though largely a long-distance transport system, the Shinkansen also serves commuters who travel to work in metropolitan areas from outlying cities.
[edit] TechnologyTo enable high-speed operation, Shinkansen uses advanced technologies compared with conventional rail, and it achieved not only high speed but also high standard of safety and comfort. Its success has influenced other railways in the world and importance and advantage of high-speed rail has been revalued consequently. [edit] Routing

[edit] PunctualityThe Shinkansen is very reliable, and 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 over roughly 160,000 Shinkansen trips completed.[5] The previous record, from 1997, was 18 seconds. [edit] History Shinkansen track is standard gauge, extremely level, with welded rails to reduce vibration. 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 proposalsThe 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 because of 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 and freight line between Tokyo and Shimonoseki that would have used steam and electric locomotives with a top speed of 200 km/h (120 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. [edit] ConstructionFollowing the end of World War II, high speed rail was forgotten for several years while traffic of passengers and freight steadily increased on the conventional Tōkaidō Main Line along with the reconstruction of Japanese industry and economy. By the mid-1950s the Tōkaidō Line was operating at full capacity, and the Ministry of Railways decided to revisit the Shinkansen project. In 1957, Odakyu Electric Railway introduced its Romancecar 3000 SE service, setting a world speed record of 145 km/h (90 mph) for a narrow gauge train. This train gave designers the confidence that they could safely build an even faster standard gauge train. Thus the first Shinkansen, the 0 Series, was built on the success of the Romancecar. In 1950s, it was widely believed that railways would soon be outdated and replaced by air travel and highways in America and many countries in Europe. However, Sogō Shinji, President of Japan National Railways, insisted strongly on the possibility of high-speed rail, and the Shinkansen project was implemented. Government approval came in December 1958, and construction of the first segment of the Tōkaidō Shinkansen between Tokyo and Osaka started in April 1959. Some of the construction was financed by an US$80 million loan from the World Bank. A test facility for rolling stock, now part of the line, opened in Odawara in 1962. [edit] Initial successThe Tōkaidō Shinkansen began service on October 1, 1964, in time for the Tokyo Olympics. The conventional Limited Express service took six hours and 40 minutes from Tokyo to Osaka, but the Shinkansen made the trip in just four hours, shortened to three hours and ten minutes by 1965. It enabled day trips between Tokyo and Osaka, the two largest metropolises in Japan, changed the style of business and life of Japanese people significantly, and increased new traffic demand. The service was an immediate success, reaching the 100 million passenger mark in less than three years on 13 July 1967, and one billion passengers in 1976. Sixteen-car trains were introduced for Expo '70 in Osaka. With an average of 23,000 passengers per hour per direction in 1992, the Tōkaidō Shinkansen is the world's busiest high-speed rail line.[6] The first Shinkansen trains, the 0 series, ran at speeds of up to 210 km/h (130 mph), later increased to 220 km/h (137 mph). The last of these trains, with their classic bullet-nosed appearance, were retired on 30 November 2008. A driving car from one of the 0 series trains is now in the British National Railway Museum in York, England. [edit] Network expansionThe Tōkaidō Line's rapid success prompted an extension westward to Hiroshima and Fukuoka (the Sanyō Shinkansen), which was completed in 1975. Prime Minister Kakuei Tanaka was an ardent supporter of the Shinkansen, and his government proposed an extensive network paralleling most existing trunk lines. Two new lines, the Tōhoku Shinkansen and Jōetsu Shinkansen, were built following this plan. Many other planned lines were delayed or scrapped entirely as Japan National Railways slid into debt throughout the late '70s, largely because of the high cost of building the Shinkansen network. By the early 1980s, the company was practically insolvent, leading to its privatization in 1987. Development of the Shinkansen continued despite this setback, however. Several new train models followed the first, each generally with its own distinctive appearance. Shinkansen trains now run regularly at speeds up to 300 km/h (186 mph), placing them alongside the French TGV, Italian TAV, Spanish AVE, and German ICE among the fastest trains in the world. Since 1970, development has also been underway for the Chūō Shinkansen, a planned maglev line 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). 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 recordDuring the Shinkansen's 44-year, nearly 7 billion-passenger history, there have been no passenger fatalities due to derailments or collisions, despite frequent 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 such mishaps. 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.[7] 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. A new anti-derailment device was installed after detailed analysis of the derailment. [edit] Economic and environmental impactThe Shinkansen has had a great effect on Japan's business, economy, society, environment and culture.[6] The time savings alone from switching from a conventional to a high-speed network have been estimated at 400 million hours, an economic impact of ¥ 500 billion per year.[6] Shinkansen connectivity has regenerated rural towns such as Kakegawa that would otherwise be too distant from major cities.[6] Travelling Tokyo-Osaka by Shinkansen produces only around 16% of the carbon dioxide of the equivalent journey by car, a savings of 15,000 tons of CO2 per year.[6] However, the vast construction costs of the Shinkansen network, particularly the later, less profitable lines often driven more by political interference than actual demand, imposed vast debt servicing costs on JNR that, by 1971, made JNR unprofitable even before depreciation.[8] JNR's Shinkansen-fueled debt eventually ballooned to ¥28 trillion and was an instrumental factor in the company's eventual privatization and breakup.[8] The privatized JRs eventually paid a total of only ¥9.2 trillion to acquire JNR's Shinkansen network.[6] [edit] Challenges encountered[edit] Noise pollutionNoise pollution concerns mean that increasing speed is becoming more difficult. In Japan, the population density is high and there have been severe protests against noise pollution of Shinkansen, and now the Shinkansen noise is regulated less than 70 dB in residential area[9]. Hence, improvement and reduction of pantograph, weight saving of cars, and construction of noise barrier and other measures have been implemented. Current research is primarily aimed at reducing operational noise, particularly the "tunnel boom" phenomenon caused when trains exit tunnels at high speed. [edit] EarthquakeBecause of the risk of large earthquake disaster, Urgent Earthquake Detection and Alarm System (UrEDAS) (earthquake warning system) has been introduced since 1992. It enables automatic braking of bullet trains in the case of large earthquakes. [edit] Heavy snowTōkaidō Shinkansen frequently encounters snow around Sekigahara, Gifu and Maibara Station in winter. Trains have to reduce speed during that time, and cars initially got disordered frequently. Later, sprinkler systems were equipped and the situation has become better, but delays of 10 to 20 minutes still occur during snowy weather. Along the route of the Jōetsu Shinkansen, winter snows can be very heavy, with snow depths of two to three metres, so the line is equipped with stronger sprinklers and slab track, to mitigate the effects of deep snow. [edit] Future[edit] Speed-upJR East has announced that the E5 Series of trains, capable of up to 320 km/h (199 mph), is to be introduced coinciding with the opening of the Tōhoku 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 (224 mph) is not currently feasible because of 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 (419 mi)). [edit] Line extensionThe 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. 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 there is no plan to convert it into a full Shinkansen line. [edit] MaglevThe CEO of JR Central announced plans to have the maglev Chūō Shinkansen operating from Tokyo to Nagoya (366 km/227 mi) by 2025. Following the shortest route (through the Japanese Alps), JR Central estimates that it will take 40 minutes to run from Tokyo to Nagoya. However, Nagano Prefecture prefers a routing that swings north to serve the city of Chino and either Ina or Kiso-Fukushima. However, this will increase both the travel time (from Tokyo to Nagoya) and the cost of construction. Maglev trains have been doing test runs on the Yamanashi test tracks since 1997, running at speeds of over 500 km/h. Because of this extensive testing, maglev technology is almost ready for public usage. [edit] Gauge Change TrainExperiments are taking place with a Gauge Change Train to enable direct operation between standard-gauge Shinkansen and narrow-gauge conventional lines; this could be useful for the Kyūshū Shinkansen branch to Nagasaki and other conventional lines. Future implementation awaits practical operational tests. [edit] List of Shinkansen linesThe main Shinkansen lines are:

Green: JR East Yellow: JR Central Blue: JR West Red: JR Kyūshū Gray: Planned Two further lines, known as "Mini-shinkansen", have also been constructed by upgrading existing sections of line: There are two standard-gauge lines not technically classified as Shinkansen lines but with Shinkansen services:
[edit] Future linesMany 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.
The following lines were also proposed in the 1973 plan, but have subsequently been shelved indefinitely.
In addition, the Basic Plan specified that the Jōetsu Shinkansen should start from Shinjuku, not Tokyo Station, which would require building an additional 30 km of track between Shinjuku and Ōmiya. While no construction work was ever started, land along the proposed track, including an underground section leading to Shinjuku Station, remains reserved. If capacity on the current Tokyo - Ōmiya section proves insufficient once the Hokkaidō and Hokuriku Shinkansen are operational, construction of the Shinjuku - Ōmiya link may be restarted. [edit] Shinkansen technology outside Japan British Rail Class 395 train in the United Kingdom, 2009 Railways using Shinkansen technology are not limited to those in Japan.
[edit] List of Shinkansen train modelsTrains 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) end to end. Stations are similarly long to accommodate these trains. Some of Japan's high-speed maglev trains are considered Shinkansen[20], while other slower maglev trains (such as Linimo maglev train line serving local community near the city of Nagoya in Aichi, Japan) are intended as alternatives to conventional urban Rapid transit systems.

[edit] List of types of Shinkansen services Tōkaidō Shinkansen Tokyo Station The Shinkansen fare system is integrated with Japan's low-speed intercity railway lines, but a surcharge is required to ride the Shinkansen. Here, an ordinary ticket from Tokyo to Takamatsu is coupled with a Shinkansen surcharge ticket from Tokyo to Okayama, allowing use of the Shinkansen from Tokyo to Okayama and use of local lines from Okayama to Takamatsu. For trips exclusively on one Shinkansen, the ordinary fare and Shinkansen surcharge may be combined on one ticket. 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 older narrow gauge network that the Shinkansen parallels.

[edit] Competition with airCompared with air transport, the Shinkansen has several advantages, including scheduling frequency and flexibility, punctual operation, comfortable seats, and convenient city-center terminals. The Shinkansen system and airlines often compete with each other for the business of city-to-city domestic travelers. If the Shinkansen connects two cities in less than three hours, most passengers choose the Shinkansen, but if it takes more than four hours by Shinkansen, the majority choose air. Some examples are as follows.
