History

In June 2016, JR Central announced plans to build a new prototype "N700S" 16-car trainset (with "S" standing for "Supreme") for evaluating new technology and features on the Tokaido and Sanyo Shinkansen lines from March 2018. [1] Developed from the earlier N700 series design, the new train will incorporate a number of new features. Refinements to the ATC and braking systems will enable shorter braking distances in emergencies such as earthquakes. [1] Optimized underfloor equipment layout will allow the same standard design to be used to easily produce 12, 8 and 6-car trainsets in addition to the Tokaido Shinkansen 16-car trainsets. [1] The optimization is intended to make the train more flexible for possible export. [2] [3] The optimization further allows Toshiba SCiB LTO batteries to be installed so that the train can operate at low speed in the event of a disruption to overhead power. [4] Green cars will use active suspension to further improve ride quality, and ordinary-class cars will have AC power outlets for each seat. [1]

A 16-car prototype set (J0), assembled at the Nippon Sharyo Toyokawa plant, was unveiled at Hamamatsu depot on 10 March 2018. [2] Beginning from 20 March, this set has been used for testing and evaluation. [2] The first full-production J set (J1) was delivered to JR Central in April 2020, with trains entering revenue service on 1 July 2020.

High-speed trials at the design speed of 360 km/h were conducted during 2019 on the Tokaido Shinkansen, reaching 362 km/h. [5] This is 28 km/h faster than the fastest speed ever achieved by the N700A, and may indicate plans to raise the maximum operating speed on the line. [6]

Operations

The first N700S sets replaced 700 series trains, and added more rolling stock needed to realize the increased amount of services on the Tokaido Shinkansen planned from 2020. [7] [8] The N700S series is expected to gradually replace N700 series sets on the Sanyo, Tokaido, and Kyushu Shinkansen lines.

The train is also planned to run on the proposed Texas Central Railway high-speed line connecting Dallas and Houston, as well as the Nagasaki Shinkansen. [9] [10]

Shinkansen Japanese high-speed rail system

The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies.

<i>Nozomi</i> (train)

Nozomi is the fastest train service running on the Tokaido & San'yō Shinkansen lines in Japan. The service stops at only the largest stations, and along the stretch between Shin-Ōsaka and Hakata, Nozomi services using N700 series equipment reach speeds of 300 km/h (186 mph). The trip between Tokyo and Osaka, a distance of 515 kilometres (320 mi), takes 2 hours 21 minutes on the fastest Nozomi service.

0 Series Shinkansen Japanese high-speed train type

The 0 series trains were the first generation Shinkansen trainsets built to run on Japan's new Tōkaidō Shinkansen high-speed line which opened in Japan in 1964. The last remaining trainsets were withdrawn in 2008.

300 Series Shinkansen Japanese high-speed train type

The 300 series was a Japanese high-speed Shinkansen train type, with a top operational speed of 270 km/h, which operated on the Tokaido and Sanyo Shinkansen lines in Japan between 1992 and 2012. When first introduced, they were used on the fastest Nozomi services, being capable of 270 km/h (170 mph). As more were delivered they replaced earlier units on Hikari service and allowed the thus displaced 100 series units to finally in turn displace 0 series units on almost all services.

500 Series Shinkansen Japanese high speed train type

The 500 series is a Shinkansen high-speed train type operated by West Japan Railway Company (JR-West) on the Tōkaidō Shinkansen and San'yō Shinkansen lines in Japan since 1997. They were designed to be capable of 320 km/h (200 mph) but operated at 300 km/h (185 mph), until they were finally retired from the primary Nozomi service in 2010. The trainsets were then refurbished and downgraded to the all-stations Kodama service between Shin-Ōsaka and Hakata.

700 Series Shinkansen Japanese high speed train type

The 700 series is a Japanese Shinkansen high-speed train type built between 1997 and 2006, and entering service in 1999. Originally designated as "N300" during the development phase, they formed the next generation of shinkansen vehicles jointly designed by JR Central and JR-West for use on the Tokaido Shinkansen, Hakata Minami Line and the San'yō Shinkansen. Though it has since been withdrawn from service on the Tōkaidō Shinkansen, it still operates on the San'yō Shinkansen and Hakata Minami Line.

Tokaido Shinkansen Shinkansen (high-speed railway) line between Tokyo and Osaka

The Tokaido Shinkansen is a Japanese high-speed rail line that is part of the nationwide Shinkansen network. Along with the Sanyo Shinkansen, it forms a continuous high-speed railway through the Taiheiyō Belt, also known as the Tokaido corridor. Upon its opening in 1964 between Tokyo and Shin-Ōsaka, it was heralded as the first high-speed rail line in the world. Since 1987 it has been operated by the Central Japan Railway Company, prior to that by Japanese National Railways (JNR). Along with being the oldest HSR line, it is also one of the most heavily used.

<i>Hikari</i> (train) Shinkansen service

Hikari is the name of a high-speed train service running on the Tokaido and San'yō Shinkansen "bullet train" lines in Japan. Slower than the premier Nozomi but faster than the all-stations Kodama, the Hikari is the fastest train service on the Tokaido and Sanyo Shinkansen that can be used with the Japan Rail Pass.

<i>Kodama</i> (train) One of the three train services running on the Tōkaidō/Sanyō Shinkansen

Kodama is one of the three train services running on the Tōkaidō and San'yō Shinkansen lines. Stopping at every station, the Kodama is the slowest Shinkansen service for trips between major cities such as Tokyo and Osaka. The Kodama trains are used primarily for travel to and from smaller cities such as Atami. Travelers between major cities generally take the Nozomi or Hikari services, which make fewer stops. The name of the train comes from the Japanese word kodama, which means "echo".

Kyushu Shinkansen

The Kyushu Shinkansen is a Japanese high-speed railway line between the cities of Fukuoka and Kagoshima in Kyushu, running parallel to the existing Kagoshima Main Line and operated by JR Kyushu. It is an extension of the San'yō Shinkansen from Honshu. The southern 127 km (79 mi) was constructed first because the equivalent section of the former Kagoshima Main Line is single track, and thus a significant improvement in transit time was gained when this dual track section opened on 13 March 2004, despite the need for passengers to change to a Relay Tsubame narrow gauge train at Shin-Yatsushiro for the remainder of the journey to Hakata. The northern 130 km (81 mi) section opened on 12 March 2011, enabling through-services to Shin-Osaka.

<i>Tsubame</i> (train)

The Tsubame (つばめ) is a train service operated by Kyushu Railway Company on the Kyushu Shinkansen in Japan since 2004.

Hokuriku Shinkansen High-speed railway line in Japan between Tokyo and Kanazawa

The Hokuriku Shinkansen (北陸新幹線) is a high-speed Shinkansen railway line jointly operated by East Japan Railway Company and West Japan Railway Company, connecting Tokyo with Kanazawa in the Hokuriku region of Japan. The first section, between Takasaki and Nagano in Nagano Prefecture, opened on 1 October 1997, originally called the Nagano Shinkansen (長野新幹線). The extension to Toyama in Toyama Prefecture and Kanazawa in Ishikawa Prefecture opened on 14 March 2015. Construction of a further section onward to Fukui and Tsuruga in Fukui Prefecture commenced in 2012, with scheduled opening in fiscal 2022. The route of the final section to Shin-Osaka was decided on 20 December 2016 as the Osaka–Kyoto route, with construction expected to begin in 2030 and take 15 years.

N700 Series Shinkansen Japanese high speed train type

The N700 series is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tokaido and San'yō Shinkansen lines since 2007, and also operated by JR Kyushu on the Kyushu Shinkansen line.

The Gauge Change Train(GCT) or Free Gauge Train is the name given to a Japanese project started in 1994 to develop a high-speed train with variable gauge axles to allow inter-running between the 1,435 mmstandard gauge Shinkansen network, and the 1,067 mm narrow gauge regional rail network.

Mizuho (train)

The Mizuho (みずほ) is a limited-stop shinkansen service operated between Shin-Osaka and Kagoshima-Chuo in Japan since 12 March 2011, following the completion of the Kyushu Shinkansen. The name was formerly used for a limited express sleeping car service operated by JNR from 1961, which ran from Tokyo to Kumamoto, and was discontinued in December 1994. The name "mizuho (瑞穂)" literally means "abundant rice" in Japanese and "harvest" in the figurative sense. It was also an ancient name of Japan.

L0 Series Japanese maglev train type

The L0 Series is a high-speed maglev train that the Central Japan Railway Company is developing and testing. JR Central plans to use the L0 series on the Chūō Shinkansen railway line between Tokyo and Osaka, which is under construction.

Sanyō Shinkansen Shinkansen (high-speed railway) line between Osaka and Fukuoka

The San'yō Shinkansen (山陽新幹線) is a line of the Japanese Shinkansen high-speed rail network, connecting Shin-Osaka in Osaka with Hakata Station in Fukuoka, the two largest cities in western Japan. Operated by the West Japan Railway Company, it is a westward continuation of the Tōkaidō Shinkansen and also serves other major cities in between on Honshu and Kyushu islands such as Kobe, Himeji, Okayama, Hiroshima, and Kitakyushu. The Kyushu Shinkansen continues south of Hakata to Kagoshima. The San'yō Shinkansen connects Hakata with Osaka in two and a half hours, with trains operating at a maximum operating speed of 300 km/h (186 mph) for most of the journey Some Nozomi trains operate continuously on San'yō and Tōkaidō Shinkansen lines, connecting Tokyo and Hakata in five hours.
