The Shinkansen (Japanese: 新幹線) is a network of high-speed railway lines in Japan operated by Japan Railways. Since the initial Tōkaidō Shinkansen opened in 1964, the network has expanded to link most major cities on the islands of Honshu and Kyushu with running speeds of up to 300 km/h (186 mph), in an earthquake and typhoon prone environment. Test run speeds have been 443km/h (275 mph) for conventional rail, and up to 580 km/h (360 mph) for maglev trainsets.

Shinkansen literally means "New Trunk Line" and hence strictly speaking refers only to the tracks, while the trains themselves are officially referred to as "Super Express" (超特急 chō-tokkyū); however, this distinction is rarely made even in Japan. In contrast to older lines, Shinkansen are standard gauge, and use tunnels and viaducts to go through and over obstacles, rather than around them.

History

Japan was the first country to build dedicated railway lines for high speed travel. Due to the largely mountainous nature of the country, the pre-existing network consisted of 3 ft 6 in gauge (1,067 mm) narrow gauge lines, which generally took indirect routes and could not be adapted to higher speeds. In consequence, 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.

Early proposals

The popular English name bullet train is a Western 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 "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 (twice the speed of the fastest Japanese train at the time). 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 formally abandoned in 1943, as Japan's position in World War II began to visibly erode. However, some construction did commence on the line; several tunnels on the present-day Shinkansen date to the war-era project.

Construction

Following Japan's defeat in 1945, high-speed rail was forgotten for several years. However, by the mid-1950's, the Tokaido Main Line was operating at full passenger 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. Much 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 Tokaido Shinkansen opened on October 11964, just in time for the Tokyo Olympics. It was an immediate success, reaching the 100 million passenger mark in less than three years on July 131967 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 200 km/h (125 mph), later increased to 220 km/h (135 mph); some of these trains, with their classic bullet-nosed appearance, are still in use. A driving car from one of the original trains is now in the British National Railway Museum in York.

Network expansion

This early success prompted an extension of the first line westward to Hiroshima and Fukuoka (the Sanyo Shinkansen), which was completed in 1975.

Prime Minister Kakuei Tanaka was an ardent supporter of the Shinkansen, and his government proposed an extensive network of lines paralleling most existing trunk lines in Japan. Two new lines, the Tohoku Shinkansen and Joetsu Shinkansen, were built following this plan. However, many other planned lines were either 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 1980's, Japan National Railway was practically insolvent, leading to its privatization in 1987.

Despite this situation, development of the Shinkansen continued. Many further models of train followed the first type, 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, German ICE, and South Korean KTX trains.

Since 1970, development has also been underway for the Chūō Shinkansen, a maglev train planned to eventually run from Tokyo to Osaka. On December 22003, the 3 car maglev trainset 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 0.1 minutes or 6 seconds of the scheduled time. This includes all natural and human accidents and errors and is calculated from all of about 160,000 trips Shinkansen made. The previous record was from 1997 and was 0.3 minutes or 18 seconds. Japan celebrated 40 years of high speed rail in 2004, with the Tōkaidō Shinkansen line alone having carried 4.16 billion passengers.

Safety record

There have been no passenger fatalities associated with operation of the Shinkansen. There have been many injuries and one fatality due to doors closing on passengers or their belongings, but attendants are on hand at each platform to ensure that these are resolved before operation begins.

There have been suicides by passengers jumping both from and in front of moving trains. This has resulted in some stations installing barriers preventing passengers from accessing the tracks, although an incident on January 9, 1999 at Sakudaira Station on the Nagano Shinkansen showed that even these would not stop determined suicides: a man climbed over a safety barrier to be hit by a non-stop service.

The first 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 長岡駅 in Nagaoka, Niigata. However, there were no injuries or deaths among the 154 passengers. * In the event of an earthquake, an earthquake detection system can bring the train to a stop very quickly; the next generation FASTECH 360 trains will have ear-like air resistance braking flaps to assist in an emergency stop at high speeds.

Future

Due to noise pollution concerns, increasing speed is becoming more difficult. Current research is primarily aimed at reducing operational noise, particularly the "tunnel boom" phenomenon caused when trains enter tunnels at high speed. Despite this, there are two planned speed increases, one to 350 km/h (217 mph) for new trains on the Sanyō line, and one to 360 km/h (223 mph) using the FASTECH 360 trains currently in testing on the Tōhoku Shinkansen.

The Kyushu 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. There are also long-term plans to extend the network, Hokkaidō Shinkansen from Aomori to Sapporo (through the Seikan Tunnel), Kyushu Shinkansen to Nagasaki, and as well as 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 it would not be feasible to convert it into a full Shinkansen line.

Operating lines

The main Shinkansen lines are:

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:

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.

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 EMUs based on the E2-1000 Series design built by a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric Corporation, and Hitachi, for deliveries starting in March 2006. For the Channel Tunnel Rail Link, Hitachi-built EMUs based on Shinkansen technology will be exported for use on high-speed commuter services in Britain.

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.

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 to allow maintenance to take place. The few overnight trains that still run in Japan run on the old narrow gauge network which the Shinkansen parallels.
