The 700 series (700系, Nanahyaku-kei) 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 Though it has since been withdrawn from service on the Tōkaidō Shinkansen, it still operates on the San'yō Shinkansen and Hakata Minami Line.

Contents

Design

The 700 series is characterized by its flat 'duck-bill' nose designed to reduce the piston effect as the trains enter tunnels. 16-car units are painted white with blue stripes beneath the windows, and are used for Nozomi , Hikari , and Kodama services on the Tokaido and San'yō Shinkansen lines, while 8-car units used for the San'yō Shinkansen Hikari Rail Star services have a darker livery (grey with black window areas and a yellow stripe beneath the windows) which also acts to visually deemphasize the units' nose area, resulting in a more streamlined impression.

As with the 500 series trains, yaw dampers are fitted between vehicles, and all cars feature semi-active suspension to ensure smooth ride characteristics at high speed. Compared with the small fleet of high-performance, high-cost 500 series trains built for JR-West, these trains were designed to give improved ride comfort and interior ambience over the earlier 300 series trains at a lower cost than the 500 series trains. The cost of a 16-car 700 series unit is approximately 4 billion yen compared with around 5 billion yen for a 16-car 500 series train.

Operations

700 series trainsets were scheduled to be withdrawn from Tokaido Shinkansen services by the end of fiscal 2019. [2] The last 700 series Tokaido Shinkansen run took place on 1 March 2020. [3] However, the 700 series still operates on the San'yō Shinkansen.

Variants

Pre-series unit (700-9000 series)

The pre-series set, C0, was delivered in October 1997, and underwent endurance running mainly between Tokyo and Shin-Osaka until early 1999, including a short period of testing as an 8-car formation on the Sanyo Shinkansen. New single-arm current collectors were fitted from the start, and these initially featured the distinctive "wine-glass" pantograph shrouds of the 300X train. These were later changed to a design resembling the 500 series arrangement with additional side fences, which was used on the subsequent production trains. Unit C0 was modified to full production standard in September 1999 and renumbered as C1, and was officially withdrawn in January 2013.

These units were ordered by JR Central for use on Tokyo to Hakata Nozomi services, displacing the 300 series trains previously used on these services. Interior layout and accommodation is similar to that of the 300 series trains, with three Green class (first class) vehicles, and the same 1,040 mm seat pitch in standard class, and 1,160 mm in Green class. The central gangways were widened by 30 mm to 600 mm, and ceilings were raised by 65 mm to 2,200 mm. The refreshment counters of the 300 and 500 series trains were discontinued and replaced by vending machines selling drinks, located in cars 3, 7, 11, and 15.

Specifications permit 285 km/h running on the Sanyo Shinkansen with speed restricted to 270 km/h on the Tokaido Shinkansen between Tokyo and Shin-Osaka. The initial batch ordered by JR Central consisted of 17 units, with the first 4 units delivered in time for introduction on three daily return Nozomi services from March 1999. Services featuring 700 series stock were increased to five daily from July 1999, and further increased from October 1999. With continuing deliveries, 700 series trains were also introduced on Tōkaidō Shinkansen Hikari services from late 2000.

Set numbers C25 onwards introduced from May 2001 incorporate minor interior design improvements, including power outlets at the ends of cars for PC users, and hand-grabs on the edge of aisle seats. An order for an additional batch of six units was placed by JR Central in December 2003, with delivery scheduled for the end of 2004. These sets (C55 to C60) provided additional capacity for services connected with the Aichi Expo in 2005.

Before entering passenger service, JR Central set C46 was used on a series of test runs from late January 2003 fitted with streamlined bogie covers on all cars and flush diaphragm covers between cars 16/15 and 15/14. These modifications were removed before the unit entered revenue service. Flush diaphragm covers were used on future trains, such as the N700 series.

Between October 2008 and June 2009, JR Central's fleet of 60 700 series sets underwent modifications to increase the acceleration from the original 1.6 km/h/s to 2.0 km/h/s (0.44 m·s−2 to 0.56 m·s−2) on the Tokaido Shinkansen to improve timetable planning flexibility. [4]

During fiscal 2011, eight JR Central "C" sets (C11 to C18) were transferred to JR-West to replace its fleet of nine 300 series sets scheduled to be withdrawn by spring 2012. [5]

Withdrawals of 700 series sets began in July 2011 with the withdrawal of set C4. It continued in 2013 (sets C1, C2, C3, C5 - C8) and in 2014 (C9, C10, C20 - C24).

The remaining 700 series sets were removed from regularly scheduled Tokaido Shinkansen services from 1 December 2019. The last Tokaido Shinkansen 700 series run from Tokyo to Shin-Osaka had been scheduled to take place on 8 March 2020, [6] but was cancelled due to the outbreak of COVID-19 in Japan. [7] This cancellation resulted in the last 700 series Tokaido Shinkansen run taking place a week earlier on 1 March 2020. [3]

These are the units owned by JR-West for use on through Hikari services from Tokyo, displacing the 100 series stock previously used on these services. A total of 15 units were delivered from June 2001 to January 2006. These trains use the same bogies as the JR-West 500 series sets. Other differences include LED destination indicator panels, white pantograph side fences, "JR 700" logos on the cab sides, and also different seat designs.

8-car E units were introduced by JR-West for use on new limited-stop Sanyo Shinkansen Hikari Rail Star services between Shin-Osaka and Hakata from 11 March 2000, replacing the former 0 series West Hikari services. The first units were delivered at the beginning of December 1999, with a total of 16 units built. Externally, these units differ noticeably from their JR Central sisters in having a variation of the 500 series livery with the blue waistline band replaced by a band of "sunny yellow". "Rail Star" logos are applied to the sides of alternate cars as well as on the cab sides. Each 8-car train has two single-arm pantographs of a similar design to the JR Central 16-car sets. It was originally planned that sets would be able to operate coupled together, enabling 16-car formations to be run in busy periods, but this feature has never been utilized. With the discontinuation of Hikari services running solely on the San'yo Shinkansen, replaced by Sakura services from 2011, these sets are primarily used on Kodama services between Shin-Osaka and Hakata.

Cars 2 and 7 each have one single-arm pantograph.

Interior

The trains feature four 4-seat compartments in car 8, and the seats at the ends of each car have power supply outlets for mobile PC users. Unlike the 0 series SK sets which they replaced, these sets are completely monoclass without Green class accommodation. However, the five reserved standard class cars, cars 4 to 8, have club class style 2+2 abreast seating compared to the normal 2+3 seating arrangement in the non-reserved cars. Seat pitch is 1,040 mm (41 in) throughout. Car 4 was also designated as a "Silence car", in which onboard announcements were omitted, but this was discontinued from March 2011. [9]

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.

100 Series Shinkansen Japanese high-speed train type

The 100 series was a Japanese Shinkansen high-speed train type which operated between 1985 and 2012 on the Tokaido Shinkansen and Sanyo Shinkansen high-speed lines. They were introduced after the 200 series trains, but their numbering is such because in the days of Japanese National Railways (JNR), Shinkansen types running east of Tokyo were given even numbers and those west of Tokyo odd numbers, hence they were given the next odd number in line after 0, 100. The last remaining examples of the type were withdrawn from service following the last runs on 16 March 2012.

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.

E3 Series Shinkansen Japanese high speed train type

The E3 series (E3系) is a Japanese Shinkansen high-speed train type built for Komachi services which commenced on 3 June 1997, coinciding with the opening of the new Akita Shinkansen "mini-shinkansen" line, a regular 1,067 mm narrow-gauge line between Morioka and Akita re-gauged to 1,435 mmstandard gauge. Later versions of the E3 series were also introduced for use on Yamagata Shinkansen Tsubasa services. Both "mini-shinkansen" lines join the Tohoku Shinkansen, providing services to and from Tokyo.

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".

800 Series Shinkansen Japanese high speed train type

The 800 series (800系) is a Japanese Shinkansen high-speed train type operated by Kyushu Railway Company on the Kyushu Shinkansen high-speed rail line. Built by Hitachi, the trains were introduced on the Tsubame services from March 2004.

<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.

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.

Sakura (train)

The Sakura is a high-speed shinkansen service operated between Shin-Osaka and Kagoshima-Chūō in Japan since 12 March 2011.

885 series Japanese train type

The E6 series (E6系) is a Japanese Shinkansen high-speed train type operated by East Japan Railway Company on Komachi "mini-shinkansen" services on the Tōhoku Shinkansen and Akita Shinkansen from Tokyo to Akita since 16 March 2013. A pre-series set was delivered in June 2010 for extensive testing, with 23 full-production sets delivered between November 2012 and spring 2014.

Class 951 Shinkansen Experimental Japanese shinkansen train

The Class 951 (951形) was an experimental Japanese Shinkansen train built to test the technology for future high-speed trains operating at speeds of up to 250 km/h (155 mph) following the opening of the Tokaido Shinkansen in 1964.

WIN350 Japanese experimental high-speed train type

"WIN350" was the name given to the 500-900 series (500系900番代) 6-car experimental high-speed Shinkansen train developed in 1992 by the West Japan Railway Company in Japan to test technology to be incorporated in next-generation shinkansen trains expected to operate at speeds of 350 km/h (217 mph) from 1994. Initially given the designation "500X", the name "WIN350" stood for "West Japan's Innovation for operation at 350 km/h".

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.

E7 and W7 Series Shinkansen Japanese high-speed train type

The E7 series (E7系) and W7 series Shinkansen are Japanese high-speed train types operated by East Japan Railway Company and West Japan Railway Company (JR-West), respectively. They were jointly developed.
