Жапондық жоғары жылдамдықты поезд – N700 сериясы

Japanese high speed train type

The N700 series (N700系) is a Japanese Shinkansen high speed train with tilting capability developed jointly by JR Central and JR West for use on the Tōkaidō and San'yō Shinkansen lines since 2007, and is operated by JR Kyushu on the Kyushu Shinkansen line. N700 series trains have a maximum speed of , and tilting of up to one degree allows the trains to maintain , even on radius curves that previously had a maximum speed of Another feature of the N700 is that it accelerates more quickly than the older 700 series Shinkansen trains, with a maximum acceleration rate of 2.6 km/h/s (0.72 m/s2). This enables it to reach in only three minutes. Further advancements led to the development of the N700A, an incremental evolution of the N700. N700A trains can reach on curves, allowing the maximum operating speed on the Tōkaidō Shinkansen to be raised to All N700 series sets have been retrofitted with most of the improvements added to the N700A series, and are now classified as "N700A". Because of these improvements, trains can travel between Tokyo and Osaka on a Nozomi run in as little as 2 hours and 22 minutes on the fastest service (8 minutes faster than before). A new train, the N700S, entered service in 2020 with plans to eventually replace all N700 series trains. The first four sets began operation on 1 July 2020.

N700 series trains gradually replaced 300, 500 and 700 series sets on Nozomi services, and by the end of February 2009, the N700 series were responsible for 74 Nozomi services per day. All Nozomi through runs (over the full route between Tokyo and Hakata) were scheduled to use the N700 series exclusively by 2009. From the start of the revised timetable on 17 March 2012, all regularly scheduled Nozomi services, including runs limited only to the Tokaido Shinkansen, were operated by N700 series sets. Since 4 March 2017, the N700 is also used on regularly scheduled Hikari services during the day, as well as all Kodama trains on the Tokaido Shinkansen, since March 2020. Since March 2009, the N700 series trains have been equipped with wireless internet available for use between Tokyo and Shin Osaka.

In an announcement by JR Central, JR West, and JR Kyushu made on 17 October 2023, the companies stated that all onboard smoking rooms on the Tokaido, San'yo, and Kyushu Shinkansen trains would be abolished by Q2 2024. In another announcement made on 14 February 2024, JR West revealed plans to convert four existing 16 car N700 series sets into 8 car formations. This move is to be made in a bid to retire four of the remaining 500 series sets on the San'yo Shinkansen. The new trains include modified brake discs, bogie vibration detection, and ATC improvements. Six "G" sets were scheduled to be introduced during fiscal 2012, replacing older 700 series sets, with seven more sets introduced during fiscal 2013. In October 2015, JR Central announced that it had ordered a further 20 N700A series sets to be delivered between fiscal 2016 and 2019, replacing all of the remaining 700 series trains sets on Tokaido Shinkansen services. The first set, G1, was delivered to Hamamatsu in August 2012, with test running commencing on the Tokaido Shinkansen the following month.

The 16 car G sets are formed as follows, with car 1 at the Shin Osaka (western) end and car 16 at the Tokyo (eastern) end.

as of 2020, the N700A series G set fleet is as follows. It was initially fitted with two auxiliary headlights located below the nose. The first full production Z set (Z1) was delivered to JR Central in April 2007, and trains entered revenue service on 1 July 2007, with eight daily Nozomi service runs. The final Z set, Z80, was delivered from Kawasaki Heavy Industries in February 2012. From fiscal 2013, the fleet of Z sets underwent modifications to incorporate some of the improvements featured in the later N700A series sets. Modified sets were re designated "X" sets, with cars renumbered in the 2000 subseries. The modified sets are also identified by the addition of a small "A" added to the right of the bodyside "N700" logos. The first original "Z" set, set Z65, was modified to become set X65 in May 2013, with the last original "Z" set, set Z4, modified to become set X4 in August 2015. The prototype set Z0 was used as a JR Central test train with cars numbered in the 9000 series, and was not used in revenue service. It was renumbered set X0 in 2014, but the car numbers remained in the 9000 subseries. The set was officially withdrawn from service in February 2019. Withdrawals of N700 series X sets commenced in July 2020, beginning with set X12.

The 8 car R sets are formed as follows.

as of 2016, the fleet consists of 11 sets, all based at Kumamoto Shinkansen Depot. Nominally specified as an 8 car set with a maximum operating speed of 330 km/h (205 mph), the train can be configured in lengths from 6 to 16 cars to suit customer requirements. The same model was being considered in the developing Houston–Dallas Texas Central Railway, before focus shifted to the N700S due to its inherently modular construction, and higher top speed.

On 16 November 2009, JR Central conducted a late night high speed demonstration run using N700 series trainset Z0, recording a maximum speed of 332 km/h (206 mph) on the Tokaido Shinkansen between and The high speed run was conducted as a demonstration for approximately 160 international guests attending a high speed railway symposium in Nagoya.

Car 783 2059 (car 1) of JR Central set X59 was scrapped due to fire damage sustained in an arson attack occurring on 30 June 2015. A replacement car with the same running number was built by Nippon Sharyo in 2016.

On 11 December 2017, Car 785 5505 (car 13) of JR West set K5 (a 16 car N700A built by Kawasaki Heavy Industries) was taken out of service at Nagoya Station after engineers confirmed an unusual burning smell. The smell was detected at Kokura Station, but was ordered by the operational centre to continue service until Nagoya which JR West later admitted was a "big danger". An on site inspection revealed that the outer frame of the carriage had cracked and its underfloor carriage was leaking oil.
