76-573: The Hokkaido Shinkansen ( 北海道新幹線 , Hokkaidō Shinkansen ) is a Japanese high-speed Shinkansen rail line that links up with the Tōhoku Shinkansen in northern Aomori Prefecture in Honshu and continues on into the interior of Hokkaido through the undersea Seikan Tunnel . Construction started in May 2005; the initial Shin-Aomori to Shin-Hakodate-Hokuto section opened on 26 March 2016. The section of

152-550: A 25 kV AC overhead power supply (20 kV AC on Mini-shinkansen lines), to overcome the limitations of the 1,500 V direct current used on the existing electrified narrow-gauge system. Power is distributed along the train's axles to reduce the heavy axle loads under single power cars. The AC frequency of the power supply for the Tokaido Shinkansen is 60 Hz. Shinkansen trains are electric multiple units (EMUs), offering fast acceleration, deceleration and reduced damage to

228-416: A temperature rating ensuring that the components of the firestop systems, including the penetrants are not permitted to rise in temperature above 140°C (284°F) on average or 180°C (356°F) at any single point, to lower the likelihood of auto-ignition on the unexposed side. In this manner, occupancy separations are treated similarly to fire walls which are structurally stable in case of a fire, thus limiting

304-459: A 387.5 km (241 mi) section of the Tōhoku Shinkansen ). Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to a world record 603 km/h (375 mph) for SCMaglev trains in April 2015. The original Tokaido Shinkansen, connecting Tokyo , Nagoya , and Osaka , three of Japan's largest cities, is one of the world's busiest high-speed rail lines. In

380-514: 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

456-733: A ceremony was held at Kikonai Station to mark the completion of track-laying for the line between Shin-Aomori and Shin-Hakodate-Hokuto. Test-running on the Hokkaido Shinkansen tracks within Hokkaido commenced from 1 December 2014, initially at low speeds, with the speed raised to the maximum of 260 km/h (160 mph) later that month. Test-running was extended through the Seikan Tunnel to Oku-Tsugaru-Imabetsu in December 2014. Test-running south of Oku-Tsugaru-Imabetsu commenced on 21 April 2015, with

532-437: A concern for residents living close to tunnel portals. The slab track consists of rails, fasteners and track slabs with a cement asphalt mortar. On the roadbed and in tunnels, circular upstands, measuring 400–520 mm (16–20 inches) in diameter and 200 mm (7.9 inches) high, are located at 5-metre intervals. The prefabricated upstands are made of either reinforced concrete or pre-stressed reinforced concrete; they prevent

608-585: A covered piggyback flatcar train) built to withstand the shock wave of oncoming Shinkansen trains traveling at full speed. This would enable a travel time from Tokyo to Shin-Hakodate-Hokuto of 3 hours and 45 minutes, a saving of 12 minutes on the current timetable. In May 2019, JR Hokkaido announced that it had requested permission from the MLIT to increase the speed limit on the 212 km (132 mi) of new track to be constructed between Shin-Hakodate-Hokuto and Sapporo to 320 km/h (200 mph). This would involve

684-535: A dispute between JR East and JR Central about the use of the two platforms which were added to the Tokaido line's half of Tokyo station. Before JNR's privatization, they were conceived as being shared with the Tohoku line, and their construction used funds allocated to the Tohoku line's extension to Tokyo; however, the extension was finished after privatization, by which time the platforms were owned by JR Central. Therefore, there

760-499: A high ride quality and less electrical equipment. ) In Japan, significant engineering desirability exists for the electric multiple unit configuration. A greater proportion of motored axles permits higher acceleration, so the Shinkansen does not lose as much time if stopping frequently. Shinkansen lines have more stops in proportion to their lengths than high-speed lines elsewhere in the world. The main Shinkansen lines are: In practice,

836-514: A high-rise building can have retail stores occupying the lower levels, while the upper levels are residential. Different occupancies within a building are separated by a fire barrier with a defined fire-resistance rating . It is common for a penetration (such as a fire door) to have a fire protection rating lower than the wall fire–resistance rating in which it is installed. For example, a two-hour fire separation normally requires fire doors rated at 90 minutes. For some high challenge occupancies,

912-579: A low-interest loan of US$ 80 million from the World Bank . Initial estimates, however, were understated and the actual cost was about 380 billion yen. As the budget shortfall became clear in 1963, Sogo resigned to take responsibility. A test facility for rolling stock, called the Kamonomiya Model Section, opened in Odawara in 1962. The Tōkaidō Shinkansen began service on 1 October 1964, in time for

988-459: A maximum speed of 130 km/h (80 mph), and 10.3 km (6.4 mi) of spur lines with Shinkansen services. The network links most major cities on the islands of Honshu and Kyushu , and connects to Hakodate on the northern island of Hokkaido . An extension to Sapporo is under construction and scheduled to open in March 2031. The maximum operating speed is 320 km/h (200 mph) (on

1064-662: A minimum curve radius of 4,000 m (13,123 ft) (2,500 m (8,202 ft) on the oldest Tōkaidō Shinkansen). The Shinkansen uses 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge in contrast to the 1,067 mm ( 3 ft 6 in ) narrow gauge of most other lines in Japan. Continuous welded rail and swingnose crossing points are employed, eliminating gaps at turnouts and crossings. Long rails are used, joined by expansion joints to minimize gauge fluctuation due to thermal elongation and shrinkage. A combination of ballasted and slab track

1140-401: A moving train to miss a switch. In particular, accretion of snow in the bogies of the train has been shown to be significant, causing damage or causing schedule delays. Methods have been used to estimate snow accumulation on trains running up to 130 km/h (81 mph), and newer estimates based on weather data can predict accumulation of up to 3 cm (1.2 in) in bogies upon arrival at

1216-672: A passenger committed suicide on board a Shinkansen train by setting himself on fire, killing another passenger and seriously injuring seven other people. There have been two derailments of Shinkansen trains in passenger service. The first one occurred during the Chūetsu earthquake on 23 October 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

1292-405: A purple stripe in the middle. The color purple was chosen to represent the purple flowers of Hokkaido: lilacs , lupine and lavender . Inside, the ordinary-class cars feature wood paneling and carpet with a snowflake motif. Green class features cream-colored walls representing the local dairy industry and carpet with a drift-ice motif. Gran class features dark blue carpets, said to be modeled after

1368-422: A range of advanced technology compared with conventional rail, achieving not only high speed but also a high standard of safety and comfort. Its success has influenced other railways in the world, demonstrating the importance and advantages of high-speed rail . Shinkansen routes never intersect with slower, narrow-gauge conventional lines (except mini-shinkansen , which runs along these older lines). Consequently,

1444-400: A standard-gauge rail has a curve with a maximum speed of 145 km/h (90 mph), the same curve on narrow-gauge rail will have a maximum allowable speed of 130 km/h (81 mph). 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. Among the key people credited with

1520-440: A station. The winter season also adversely impacts the occupancy rates of the rail line, with recorded occupancy reaching a low of 19% in the months of January and February. Legend: All services are formed of 10-car JR East E5 or JR Hokkaido H5 series trainsets. In February 2014, JR Hokkaido placed an order for four 10-car H5 Series Shinkansen trainsets for use on Hokkaido Shinkansen services from March 2016. Based on

1596-659: A trainset in order to perform high-speed tests. 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 the 1950s, the Japanese national attitude was that as was happening in the United States, railways would soon be outdated and replaced by air travel and highways. However, Shinji Sogō , President of Japanese National Railways , insisted strongly on

These are typically more advanced than motion sensors , which can only detect motion . In transport engineering , occupancy can refer to: In football , occupancy can refer to: In combat sports such as boxing and Mixed martial arts , as well as in Pro Wrestling , the term vacant

1824-714: Is no through service between those lines. All northbound services from Tokyo travel along the Tohoku Shinkansen until at least Ōmiya before splitting off towards Sendai or Takasaki. Two further lines, known as Mini-shinkansen , have also been constructed by re-gauging and upgrading existing sections of line: There are two standard-gauge lines not technically classified as Shinkansen lines but run Shinkansen trains as they use tracks leading to Shinkansen storage/maintenance yards: The following lines are under construction. These lines except Chūō Shinkansen , called Seibi Shinkansen  [ ja ] or planned Shinkansen , are

1900-408: Is scheduled to be completed by March 2021. The 211.3 km (131.3 mi) extension will be approximately 76% in tunnels, including major tunnels such as Oshima (26.5 km or 16.5 mi), Teine (18.8 km or 11.7 mi) and Shiribeshi (18 km or 11 mi). When the section to Sapporo opens, the estimated journey time from Tokyo to Sapporo will be at most 5 hours and 1 minute, but

1976-490: Is used today in English-language announcements and signage. Japan was the first country to build dedicated railway lines for high-speed travel. Because of the mountainous terrain, the existing network consisted of 1,067 mm ( 3 ft 6 in ) narrow-gauge lines, which generally took indirect routes and could not be adapted to higher speeds due to technical limitations of narrow-gauge rail. For example, if

2052-414: Is used when a championship does not currently not have a champion, this often occurs if a current champion is unable to defend a title. This is often due to reasons such as the champion suffering an injury or illness, leaving a promotion for another, being fired from a promotion, failing to make weight for a fight, having a contract dispute, failing a post-fight drug test, being arrested, inactivity, moving up

2128-431: Is used, with slab track exclusively employed on concrete bed sections such as viaducts and tunnels. Slab track is significantly more cost-effective in tunnel sections, since the lower track height reduces the cross-sectional area of the tunnel, reducing construction costs up to 30%. However, the smaller diameter of Shinkansen tunnels, compared to some other high-speed lines, has resulted in the issue of tunnel boom becoming

2204-662: 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 was donated by JR West to the National Railway Museum in York , United Kingdom in 2001. The Tōkaidō Shinkansen's rapid success prompted an extension westward to Okayama , Hiroshima and Fukuoka (the San'yō Shinkansen ), which

2280-539: The E5 series trainsets operated by JR East since 2011, the order for 40 vehicles cost approximately 18 billion yen. The first two sets of the order are scheduled to be delivered to Hakodate Depot by road from Hakodate Port in October 2014, with test running commencing before the end of the year. The remaining two sets on order were scheduled to be delivered in 2015. The vehicles feature the usual upper green and lower white livery, with

2356-730: The Narita Sky Access Line which opened in 2010, and the Keiyo Line reused space originally set aside for the Narita Shinkansen terminus at Tokyo Station . Although the Sky Access Line uses standard-gauge track, it was not built to Shinkansen specifications and there are no plans to convert it into a full Shinkansen line. Many Shinkansen lines were proposed during the boom of the early 1970s but have yet to be constructed and have subsequently been shelved indefinitely. In addition,

2432-582: 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. Following the end of World War II, high-speed rail was forgotten for several years while traffic of passengers and freight steadily increased on

2508-677: The Tōhoku Shinkansen ; only the Shanghai maglev train , China Railway High-speed networks, and the Indonesian Jakarta-Bandung High-speed railway have commercial services that operate faster. Since 1970, development has also been underway for the Chūō Shinkansen , a planned maglev line from Tokyo to Osaka. On 21 April 2015, a seven-car L0 series maglev trainset set a world speed record of 603 km/h (375 mph). To enable high-speed operation, Shinkansen uses

2584-431: The first 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, significantly changed the style of business and life of the Japanese people, and increased new traffic demand. The service

2660-622: The largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies. Starting with the Tokaido Shinkansen (515.4 km; 320.3 mi) in 1964, the network has expanded to consist of 2,951.3 km (1,833.9 mi) of lines with maximum speeds of 260–320 km/h (160–200 mph), 283.5 km (176.2 mi) of Mini-shinkansen lines with

2812-636: The 154 passengers. Another derailment happened on 2 March 2013 on the Akita Shinkansen when the Komachi No. 25 train derailed in blizzard conditions in Daisen, Akita . No passengers were injured. In the event of an earthquake, an earthquake detection system can bring the train to a stop very quickly; newer trainsets are lighter and have stronger braking systems, allowing for quicker stopping. New anti-derailment devices were installed on tracks after analysis of

2888-565: The Basic Plan specified that the Jōetsu Shinkansen should start from Shinjuku , not Tokyo Station , which would have required building an additional 30 km (19 mi) 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 Tokyo–Ōmiya section proves insufficient at some point, construction of

2964-504: The Jōetsu derailment. Several months after the exposure of the Kobe Steel falsification scandal , which is among the suppliers of high-strength steel for Shinkansen trainsets, cracks were found upon inspection of a single bogie , and removed from service on 11 December 2017. Occupancy It is possible to have multiple occupancies (or building uses) within one building. For example,

3040-520: The L0 series could be a passenger train. The Shinkansen is very reliable thanks to several factors, including its near-total separation from slower traffic. There are separate laws governing interfering with or otherwise obstructing Shinkansen trains, tracks, or its operation. In 2016, JR Central reported that the Shinkansen's average delay from schedule per train was 24 seconds. This includes delays due to uncontrollable causes, such as natural disasters. Over

3116-609: The Shinjuku–Ōmiya link may be reconsidered. In December 2009, then transport minister Seiji Maehara proposed a bullet train link to Haneda Airport , using an existing spur that connects the Tōkaidō Shinkansen to a train depot. JR Central called the plan "unrealistic" due to tight train schedules on the existing line, but reports said that Maehara wished to continue discussions on the idea. The succeeding minister has not indicated whether this proposal remains supported. While

3192-540: The Shinkansen projects designated in the Basic Plan of the Shinkansen Railway  [ ja ] decided by the government. 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 were used by

3268-500: The Shinkansen's 60-plus year history, carrying over 10 billion passengers, there have been no passenger fatalities due to train accidents such as 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 accidents. There have, however, been suicides by passengers jumping both from and in front of moving trains. On 30 June 2015,

3344-526: The Tokaido, San'yō, and Kyushu lines form a contiguous west/southbound line from Tokyo, as train services run between the Tokaido and San'yō lines and between the San'yō and Kyushu lines, though the lines are operated by different companies. The Tokaido Shinkansen tracks are not physically connected to the lines of the Tohoku Shinkansen at Tokyo Station, as they use different electrification standards, signaling systems, and earthquake mitigation devices. There also exists

3420-534: The approximately 82 km (51 mi) dual gauge section of the Hokkaido Shinkansen (including through the Seikan Tunnel ) was 140 km/h (85 mph), increased to 160 km/h (99 mph) in March 2019. There are approximately 50 freight trains using the dual gauge section each day, so limiting the travel of such trains to times outside of Shinkansen services is not an option. Because of this and other weather-related factors cited by JR East and JR Hokkaido,

3496-559: The code requirements for an occupancy separation are more stringent than for other fire barriers, even with an identical fire resistance rating. In this case, an occupancy separation with a two-hour fire-resistance rating may not be able to "de-rate" its closures, such fire doors and firestops . For example, a two-hour rated "high challenge fire wall" requires two-hour rated fire doors. Firestops in occupancy separations are also more likely to require an equal fire protection rating (a fire resistance rating for closures). They also must provide

3572-578: The construction of the first Shinkansen are Hideo Shima , the Chief Engineer, and Shinji Sogō , the first President of Japanese National Railways (JNR) who managed to persuade politicians to back the plan. Other significant people responsible for its technical development were Tadanao Miki, Tadashi Matsudaira, and Hajime Kawanabe based at the Railway Technical Research Institute (RTRI), part of JNR. They were responsible for much of

3648-528: 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 3000 series SE Romancecar train, setting a world speed record of 145 km/h (90 mph) for a narrow gauge train when JNR leased

3724-525: The conventional loading gauge for 1,067mm lines still applies on mini-Shinkansen lines. The Shinkansen has used EMUs from the outset, with the 0 Series Shinkansen having all axles powered. Other railway manufacturers were traditionally reluctant or unable to use distributed traction configurations ( Talgo , the German ICE 2 and the French (and subsequently South Korean) TGV (and KTX-I and KTX-Sancheon ) use

3800-558: The danger of fire-induced building collapse. In this sense, there are two occupancies in many single-family homes : the garage and the living space of the home . Because automobile gasoline is flammable , an occupancy separation is often required between the two should there be a vehicle fire . Water heaters and central heating are often placed in this space as well for their use of natural gas , propane , or other fossil fuels in combustion . This also helps to prevent carbon monoxide poisoning . Occupancy can also refer to

3876-709: The effects of the COVID-19 pandemic ), rail projects in the vicinity of Haneda Airport, including the Haneda Airport Access Line and the Tokyo Rinkai Subway Line , continue to undergo planning. Originally intended to carry passenger trains by day and freight trains by night, the Shinkansen lines carried exclusively passengers for the first five and a half decades of their operation. Lght freight has been carried on some passenger services since 2019, and there are plans to expand this with freight-only trains in

Operating in areas that see significant snowfall during the winter months, accumulation of snow has effects on various train operations. It can cause damage to equipment or can cause

4028-571: The fastest journey time between Tokyo and Shin-Hakodate-Hokuto is currently 3 hours, 57 minutes. During the 2020-21 New Year Holiday period when fewer freight trains were operating, certain Shinkansen services were operated at 210 km/h (130 mph) on the dual gauge section and this is proposed again for the Golden Week Holiday period from 3–6 May 2021 This raising of the maximum speed during major travel periods has been repeated every year since. In January 2024, JR Hokkaido announced that

JR Hokkaido is extending the Hokkaido Shinkansen from Shin-Hakodate-Hokuto to Sapporo , planned to open by 2030. However, in May 2024, the JRTT reported to the MLIT that it would be 'extremely difficult' to extend the line to Sapporo by 2030. Tunneling work on the 5,265 m (3.272 mi) Murayama Tunnel, situated about 1 kilometer (0.6 mi) north of Shin-Hakodate-Hokuto station commenced in March 2015; it

4180-896: The future. The system shuts down between midnight and 06:00 every day for maintenance. Japan's few remaining overnight passenger trains run on the older, narrow-gauge network that the Shinkansen parallels. There are three principal service types on the Shinkansen: Trains are 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, while other slower maglev trains (such as Linimo , serving local communities in and nearby Nagoya , Aichi Prefecture ) are intended as alternatives to conventional urban rapid transit systems. These trains were and are used only for experimental runs, though

Shinkansen The Shinkansen ( Japanese : 新幹線 , [ɕiŋkaꜜɰ̃seɴ] , lit.   ' new trunk line ' ) , colloquially known in English as the bullet train , is a network of high-speed railway lines in Japan . It was initially built to connect distant Japanese regions with Tokyo , the capital, to aid economic growth and development. Beyond long-distance travel, some sections around

4332-461: 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 by the privatised regional JR companies has continued, with new train models developed, each generally with its own distinctive appearance (such as the 500 series introduced by JR West ). Since 2014, Shinkansen trains run regularly at speeds up to 320 km/h (200 mph) on

4408-453: The highest annual passenger ridership (a maximum of 386 million in 2007) of any high-speed rail network until 2011, when the Chinese high-speed railway network surpassed it at 370 million passengers annually, reaching over 2.9 billion annual passengers in 2023. Shinkansen ( 新幹線 ) in Japanese means 'new trunk line' or 'new main line', but this word is used to describe both the railway lines

4484-415: The initial timetable, ten return Hayabusa services operate daily between Tokyo and Shin-Hakodate-Hokuto and one return service operates daily between Sendai and Shin-Hakodate-Hokuto. One return Hayate service operates daily between Morioka and Shin-Hakodate-Hokuto, and one return service daily operates between Shin-Aomori and Shin-Hakodate-Hokuto. Upon commencement of services in 2016 the maximum speed on

4560-584: The line to Sapporo is scheduled to open by fiscal year 2030. The line is operated by the Hokkaido Railway Company (JR Hokkaido). In preparation for the opening of the Hokkaido Shinkansen, the Seikan Tunnel ( Kaikyō Line ) and associated approaches (approximately 82 km or 51 mi in total) were converted to dual gauge , with both the Shinkansen 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard and 1,067 mm ( 3 ft 6 in ) narrow gauge tracks. Upon

On occasions, this wider loading gauge was also used to allow 6-abreast seating (3+3) on certain trains, such as the E1 and E4 series sets. This, combined with a lack of power cars, allows for a higher passenger capacity within a shorter train length. However, since mini-Shinkansen lines are effectively track-regauged conventional lines,

4712-432: The number of persons using an undivided space, such as a meeting room , ballroom , auditorium , or stadium . As with building codes, fire protection authorities often set a limit on the number of people that can occupy a space at one time. These limits are established primarily to allow all occupants safe passage through exits , but can also be employed to preserve the integrity of a structure . An occupancy sensor

4788-425: The number of units in use, such as hotel rooms , apartment flats , or offices . When a motel is at full occupancy, it is common practice to turn on a NO VACANCY neon sign . Completely vacant buildings can also attract crime . A 2017 study found that demolishing vacant buildings "reduce crime by about 8 percent on the block group in question and 5 percent on nearby block groups". Occupancy can also refer to

5016-591: The plan may become more feasible after the opening the Chūō Shinkansen (sometimes referred to as a bypass to the Tokaido Shinkansen) frees up capacity, construction is already underway for other rail improvements between Haneda and Tokyo station expected to be completed prior to the opening of the 2020 Tokyo Olympics , so any potential Shinkansen service would likely offer only marginal benefit. Despite these plans ultimately not being realized (owing in part due to

5092-402: 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. The cost of constructing the Shinkansen was at first estimated at nearly 200 billion yen, which was raised in the form of a government loan, railway bonds and

5168-419: The shimmering lakes and bodies of water along the route. In the early 1970s, two other Shinkansen routes were proposed for Hokkaido: Sapporo – Asahikawa (Hokkaido Shinkansen extension) and Oshamambe – Muroran – Sapporo (Hokkaido South Route). There were also further unofficial plans to connect to Abashiri , Kushiro and Nayoro / Wakkanai . These plans have been indefinitely shelved. On 1 November 2014,

5244-573: The shinkansen is not affected by slower local or freight trains (except for Hokkaido Shinkansen while traveling through the Seikan Tunnel ), and has the capacity to operate many high-speed trains punctually. In addition, shinkansen routes (excluding mini-shinkansen) are completely grade separated from roads and highways, meaning railway crossings are almost eliminated. Tracks are strictly off-limits with penalties against trespassing strictly regulated by law. The routes use tunnels and viaducts to go through and over obstacles rather than around them, with

5320-515: The speed would be raised to 260 km/h (160 mph)) during major holidays going forward. To achieve the full benefit of Shinkansen trains travelling on the dual gauge section at 260 km/h (160 mph) (the maximum speed proposed through the tunnel), alternatives are being considered, such as a system to automatically slow Shinkansen trains to 200 km/h (125 mph) when passing narrow-gauge trains, and/or loading freight trains onto special " Train on Train " standard-gauge trains (akin to

5396-407: The technical development of the first line, the Tōkaidō Shinkansen . All three had worked on aircraft design during World War II . 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 discussed in the 1930s. The name stuck because of the original 0 Series Shinkansen 's resemblance to

5472-501: The track because of the use of lighter vehicles compared to locomotives or power cars. The coaches are air-sealed to ensure stable air pressure when entering tunnels at high speed. Shinkansen trains (excluding mini-Shinkansen) are also built to a larger loading gauge compared to conventional-speed rolling stock. This larger loading gauge permits wider coaches, allowing for 5-abreast seating (2+3) in Standard Class coaches, compared to

5548-697: The track slab from moving latitudinally or longitudinally. One track slab weighs approximately 5 tons and is 2,220–2,340 mm (87–92 inches) wide, 4,900–4,950 mm (193–195 inches) long and 160–200 mm (6.3–7.9 inches) thick. The Shinkansen employs an ATC (Automatic Train Control) system, eliminating the need for trackside signals. It uses a comprehensive system of Automatic Train Protection . Centralized traffic control manages all train operations, and all tasks relating to train movement, track, station and schedule are networked and computerized. Shinkansen uses

5624-420: The trains run on and the trains themselves. In English, the trains are also known as the bullet train. The term bullet train ( 弾丸列車 , dangan ressha ) originates from 1939, and was the initial name given to the Shinkansen project in its earliest planning stages. Furthermore, the name super express ( 超特急 , chō-tokkyū ) , used exclusively until 1972 for Hikari trains on the Tōkaidō Shinkansen ,

5700-680: 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 in each direction in 1992, the Tōkaidō Shinkansen was the world's busiest high-speed rail line. As of 2014, the train's 50th anniversary, daily passenger traffic rose to 391,000 which, spread over its 18-hour schedule, represented an average of just under 22,000 passengers per hour. The first Shinkansen trains,

5776-410: 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 JNR slid into debt throughout the late 1970s, largely because of
