N700 series trains have a maximum speed of 300 km/h (186 mph), and tilting of up to one degree allows the trains to maintain 270 km/h (168 mph) even on 2,500 m (8,200 ft) radius curves that previously had a maximum speed of 255 km/h (158 mph). Another feature of the N700 is that it accelerates quicker 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 270 km/h (170 mph) in only three minutes. Further advancements led to the development of the N700A, an incremental evolution of the N700. N700A trains can reach 285 km/h on 3,000 m curves, allowing the maximum operating speed on the Tōkaidō Shinkansen to be raised to 285 km/h. 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).

Currently, a second revision to the N700 series, the N700S, is undergoing testing and evaluation, with plans to begin replacing all other models from 2020. The first four sets began operation on 1 July 2020.

Operations

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.[3] 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.[4]

Since 4 March 2017, the N700 is also used on regularly scheduled Hikari services during the day, as well as almost all Kodama trains on the Tokaido Shinkansen. Since March 2009, the N700 series trains have been equipped with wireless internet available for use between Tokyo and Shin-Osaka.[5]

N700 series trainsets are also planned to run on the proposed Texas Central Railway high-speed line connecting Dallas and Houston.[6]

16-car G sets (N700-1000 series "N700A")
Set G15, December 2015

The N700-1000 series, or "N700A" (with "A" standing for "Advanced"), is a new version of the N700 series design delivered from August 2012, and entering revenue service from 8 February 2013.[7]

The new version is externally identical to the existing N700 series sets, with the addition of new "N700A" logos on each odd-numbered car.[8] The new trains include modified brake discs, bogie vibration detection, and ATC improvements.[9]

Six "G" sets were scheduled to be introduced during fiscal 2012, replacing older 700 series sets, with seven more sets introduced during fiscal 2013.[10] A further 18 sets are on order by JR Central, to be delivered six sets per year between fiscal 2014 and 2016 at a cost of 88 billion yen.[11] 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.[12]

The first set, G1, was delivered to Hamamatsu in August 2012, with test running commencing on the Tokaido Shinkansen the following month.[13]

16-car X sets (N700-2000 series "N700A")
JR Central N700-2000 series set X50, September 2014
  • 81 x 16-car sets, X0–X80 (converted from N700-0 series)

These are former N700 series Z sets modified between 2013 and August 2015 to incorporate some of the design improvements featured in the later N700A series sets. Cars are renumbered in the -2000 subseries, with the exception of set X0, which is still numbered in the -9000 subseries. The sets are also identified by the addition of a small "A" added to the right of the bodyside "N700" logos.[15] The prototype 16-car train (Z0) was delivered in March 2005 for extensive testing and endurance running. Cars 1 to 4 were built by Hitachi, cars 5 to 14 were built by Nippon Sharyo, and cars 15 and 16 were built by Kawasaki Heavy Industries.[16] It was initially fitted with two auxiliary headlights located below the nose.[17]

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.[18]

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.[15] 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.[14]

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.[7] The set was officially withdrawn from service in February 2019.

Withdrawals of N700 series X sets commenced in July 2020, beginning with set X12.

16-car K sets (N700-5000 series "N700A")
  • 16 x 16-car sets, K1–K16 (Converted from N700-3000 series)
JR-West N700-5000 series set K6, January 2016

These are JR-West trainsets modified from October 2013 from former N700 series N sets to incorporate some of the design improvements featured in the later N700A series sets.[22]

Former N sets

The 16-car N sets were operated by JR-West on Tokaido and Sanyo Shinkansen services. The first set, N1, was delivered in June 2007, entering service on 1 July 2007.[7] 16 sets were in service by April 2014.[7]

The fleet of 16 "N" sets subsequently underwent modifications at Hakata Depot between fiscal 2013 and fiscal 2015 to add improved braking systems and other features incorporated in the later N700A series sets.[22] Modified sets were re-designated "K" sets, with cars renumbered in the -5000 subseries.[22]

16-car J sets "N700S"

In June 2016, JR Central announced plans to build a new prototype "N700S" 16-car trainset for evaluating new technology and features on the Tokaido and Sanyo Shinkansen lines from March 2018.[29] 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.[29] Optimized underfloor equipment layout will allow the same standard design to be used to produce 12-car and 8-car trainsets in the future in addition to the Tokaido Shinkansen 16-car trainsets.[29] The optimization is intended to make the train more flexible for possible export.[30][31] 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.[32] Green cars will use active suspension to further improve ride quality, and ordinary-class cars will have AC power outlets for each seat.[29]

A 16-car prototype set (J0), assembled at the Nippon Sharyo Toyokawa plant, was unveiled at Hamamatsu depot on 10 March 2018.[30] Beginning from 20 March, this set has been used for testing and evaluation.[30] The first full-production J set (J1) was delivered to JR Central in April 2020, with trains entering revenue service on 1 July 2020. Currently, there are just four full-production sets operating on the Tokaido and Sanyo Shinkansen lines since 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.[33] 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.[34][35]

The 16-car J sets are formed as follows.

N700-I Bullet

This was a proposed export version of the N700 series design announced by JR Central Chairman Yoshiyuki Kasai at an international high-speed railway symposium held in Nagoya on 16 November 2009.[36] 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.[37][38]

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.[39]

High-speed trials

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 Maibara and Kyōto. The high-speed run was conducted as a demonstration for approximately 160 international guests attending a high-speed railway symposium in Nagoya.[34][35]

Incidents

Fire damage and replacement

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.[40]

Discovery of cracked bogie

On 11 December 2017, Car 785-5505 (carriage 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.[41] 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".[42][43] An on-site inspection revealed that the outer frame of the carriage had cracked and its underfloor carriage was leaking oil.[43] It was the first "serious incident" involving any Shinkansen, and Ministry of Land, Infrastructure, Transport and Tourism reported that the train could have derailed had it continued on service and the carriage frame broke.[41] An investigation by JR West implicated companies involved in the construction of the trainset, which included Kawasaki Heavy Industries, Nippon Steel and Mitsubishi Electric.[42] The investigation revealed that at least 100 out of the 303 Kawasaki-made bogies were substandard due to improper welding preparations, which caused the base material of the bogies to become 4.7mm in thickness, instead of the required 7mm or more. Following the events JR West is planning to gradually replace all the bogies that were provided by Kawasaki.[44]

gollark: Apparently SSDs are roughly as reliable as HDDs, if not more so because of no moving parts.
gollark: They are VERY suitable for servers because servers often need high performance I/O, and are still pretty reliable.
gollark: This is because they are bees.
gollark: SolarFlame5 does not like SSDs.
gollark: Unrelatedly, I'm going to rework the potatOS logging mechanism.
